Overview

The Romicta BT-398 Stereo Amplifier is a compact, budget-conscious unit that punches above its weight in terms of input variety. Before anything else, understand the wattage story: the 60W+60W rated power is what you will actually hear day-to-day — the 450W peak figure is a momentary ceiling, not a sustained output. For the price, the input lineup is genuinely surprising, covering Bluetooth 5.0, optical, coaxial, RCA, USB, SD card, FM radio, and even a microphone jack. It also supports both passive speakers and active subwoofers simultaneously, which most rivals at this price simply do not offer. The chassis is small enough to sit on a shelf or beside a monitor without dominating the space.

Features & Benefits

The BT-398's Bluetooth 5.0 connection is notably quiet — no audible pop when pairing, which matters if you have dealt with cheaper amps that crackle on connect. Keep your source within 30 feet in an open room; if you are streaming from a TV or PC, halve that distance to stay safe. The optical and coaxial inputs are a genuine highlight, letting you plug directly into a modern TV's digital output without hunting for a separate converter box. Bass and treble knobs give you tactile control, and the included remote handles adjustments from across the room. On the specs side, 0.04% THD and a 95dB signal-to-noise ratio suggest cleaner audio than most amps in this category typically deliver.

Best For

This compact stereo amp is a natural fit for anyone building audio around a small living space — a bedroom, a studio apartment, or a desk setup where a full-size receiver would feel excessive. It handles the less common scenario of running passive bookshelf speakers and a powered subwoofer from the same unit, which simplifies wiring considerably. If you want to connect your TV via optical without buying a separate A/V receiver, this home audio amplifier covers that without fuss. It also works well for casual karaoke nights or garage sessions, where the mic input and FM radio feel practical rather than gimmicky. This is not an audiophile tool — it is a versatile everyday solution for modest, space-conscious setups.

User Feedback

With over 550 ratings and a 4.2-star average, buyer sentiment leans clearly positive. The most common praise centers on value for money — getting optical, Bluetooth, and subwoofer support in one small box at this price point is the theme that keeps surfacing. On the critical side, some buyers feel the real-world power output is modest compared to the marketed peak figures, which is expected once you separate rated from peak wattage. A handful of reviewers flag the lightweight plastic chassis as feeling less premium in hand. Occasional Bluetooth dropout also surfaces when walls sit between the amp and the source device, and the remote control range draws mixed comments — functional, but not built for distance.

Ratings

The Romicta BT-398 Stereo Amplifier has been scored by our AI system after analyzing hundreds of verified global purchases, with spam, incentivized, and bot-flagged reviews actively filtered out before any scoring took place. The ratings below reflect what real buyers experienced across diverse setups — from bedroom desks to garage speaker rigs — and both the strengths and the frustrations are represented without sugar-coating.

Value for Money
91%
Buyers consistently express surprise at how much functionality this compact stereo amp delivers at its price point. Getting optical input, subwoofer output, Bluetooth 5.0, FM radio, and a remote in a single unit — without spending significantly more — is what drives most of the positive sentiment in reviews.
A minority of buyers feel slightly misled by the headline wattage figures before understanding the peak-versus-rated distinction, which can make the initial purchase feel less impressive than expected until the unit is actually heard in a real room.
Input Versatility
88%
The breadth of connections on the BT-398 is genuinely unusual at this tier. Buyers setting up mixed-source systems — a TV via optical, a phone via Bluetooth, and a turntable via RCA — appreciate not having to swap cables or buy a separate switcher box to manage different devices.
Switching between input modes requires either pressing the front panel button repeatedly or using the remote, and a few users find the input cycling logic slightly unintuitive at first, particularly when the unit defaults back to a previous source after being powered off and on again.
Bluetooth Performance
74%
26%
The Bluetooth 5.0 chip handles pairing quickly and, in open rooms, holds a stable connection with noticeably less background hiss than older-generation budget amps. Users streaming music from a phone or tablet within a typical bedroom distance report clean, uninterrupted playback.
Range drops meaningfully in real home environments with walls involved — the 15-foot guidance for TV and PC connections is a real constraint. Several buyers using this home audio amplifier in living rooms report dropouts when the TV sits across the room, especially in apartments with denser construction.
Optical & Coaxial Input Quality
83%
For TV users specifically, the digital inputs are a standout feature. Connecting a modern TV's optical output directly to the BT-398 delivers noticeably cleaner audio than an analog RCA run, and buyers replacing entry-level soundbars praise the improvement in dialogue clarity through bookshelf speakers.
The optical input does not support Dolby Digital decoding — it handles PCM stereo only, which means 5.1 audio from streaming apps gets downmixed. This is standard behavior for a stereo amp but catches some buyers off guard if they were expecting surround passthrough.
Power Output & Volume Headroom
67%
33%
For compact bookshelf speakers in rooms up to roughly 200 square feet, the 60W per channel rating delivers enough volume to fill the space comfortably. Users running efficient passive speakers in bedrooms and offices rarely need to push the volume knob past the halfway point during normal listening.
Buyers with larger rooms or less efficient speakers regularly report hitting the volume ceiling before reaching satisfying loudness levels. The 450W peak marketing sets expectations that the sustained output cannot always meet, and this gap frustrates users who were hoping to drive floor-standing speakers at higher volumes.
Build Quality & Materials
62%
38%
The chassis is compact and tidy, with a clean front panel layout that does not look out of place in a home A/V setup. The control knobs have a reasonable amount of resistance and feel stable during adjustment, which is not always the case with competitors at similar prices.
At 1.5 kg, the unit feels noticeably light — something buyers notice immediately when unboxing. The outer casing is plastic rather than brushed metal, and several reviewers mention that the housing flexes slightly under pressure, raising mild concerns about long-term durability in a high-use environment.
Remote Control
61%
39%
Having a remote included at this price is a genuine convenience, and buyers using this in bedroom or couch setups appreciate being able to adjust bass, treble, and volume without getting up. It covers the core functions most users need for hands-free daily operation.
The remote's effective range draws criticism — several users report needing to point it precisely and stay within a fairly short distance for reliable response. Build quality of the remote itself is also described as basic, with a lightweight plastic feel that does not inspire long-term confidence.
FM Radio Functionality
78%
22%
Including an FM tuner with a physical antenna is a small but appreciated touch, especially for buyers in garages or workshops who want background radio without a separate device. Reception quality with the included antenna is reported as solid in urban and suburban environments.
In rural areas or locations with weaker FM signal coverage, reception becomes noticeably patchy without an upgraded antenna. The tuner interface is basic — there is no digital display showing station frequencies on some units, making precise tuning feel more trial-and-error than it should.
Subwoofer Output
76%
24%
Buyers running a powered subwoofer alongside passive bookshelf speakers specifically call out the dedicated subwoofer output as the reason they chose the BT-398 over alternatives. The low-frequency channel blends acceptably with the main speakers in most casual listening setups without obvious phasing issues.
There is no dedicated subwoofer level control on the unit itself — output level depends on the subwoofer's own gain knob. A handful of users with more demanding active subs mention the output signal feels slightly weak, requiring the sub's internal gain to be turned up higher than ideal.
Sound Clarity & Audio Quality
73%
27%
For a budget amp, the measured specs — 0.04% THD and a 95dB signal-to-noise ratio — translate to a cleaner listening experience than the price suggests. At moderate volumes through decent bookshelf speakers, buyers describe the sound as balanced and free from the background hiss common in cheaper class-D amplifiers.
At higher volume levels, some compression and mild distortion become audible, particularly in the upper midrange. Listeners with more trained ears or better-quality speakers will notice the ceiling sooner; this amp is not positioned for critical or high-resolution listening sessions.
Bass & Treble Controls
79%
21%
Having physical knobs for both bass and treble — rather than a single tone control or none at all — gives users meaningful ability to tune the sound to their speakers and room. Buyers in rooms with reflective surfaces appreciate being able to roll off excess treble without diving into any settings menu.
The tonal adjustment range is moderate rather than wide. Users trying to significantly compensate for bass-heavy rooms or bright-sounding speakers may find the knobs reach their limits before the sound is fully corrected, and there is no mid-range control for more nuanced shaping.
Setup & Ease of Use
86%
Most buyers describe getting the BT-398 up and running in under ten minutes. The front panel labeling is clear, Bluetooth pairing is straightforward, and the included accessories — antenna, power cable, remote — mean there is very little else to source before the unit is functional out of the box.
The instruction manual is thin and could explain input mode switching more clearly for less experienced buyers. A few users also missed the note about removing the plastic insulation tab from the remote battery compartment, causing confusion about why the remote was not working initially.
Compact Design & Form Factor
84%
The small footprint is a genuine selling point for space-constrained setups. Buyers in studio apartments and on cluttered desks consistently mention that the BT-398 slots into tight spots where a conventional receiver simply would not fit, without sacrificing the core functions they need.
Ventilation is limited by the compact housing, and a few buyers in warmer climates or enclosed cabinets report that the unit gets noticeably warm during extended use. Running it inside a fully enclosed A/V cabinet without airflow is not recommended based on user experience.
Power Supply Flexibility
81%
19%
Supporting both DC 12V–24V and AC 110V–220V in the same unit is a practical advantage that most comparable amps do not offer. Buyers who travel internationally or want to use this in a vehicle context appreciate not needing a voltage converter or separate power brick.
The DC power cable for vehicle or battery use is not included in the box — only the standard AC cable ships with the unit. Buyers expecting plug-and-play car audio use need to source the appropriate DC connector separately, which is a minor but frustrating discovery after purchase.

Suitable for:

The Romicta BT-398 Stereo Amplifier is a strong match for anyone building a capable audio setup in a limited space without spending heavily on a full-size receiver. Apartment dwellers, bedroom listeners, and desktop audio builders will find it covers most practical needs in a footprint smaller than a hardcover book. It particularly shines for users who want to connect a TV via optical cable and run passive bookshelf speakers alongside a powered subwoofer — a combination that typically requires a more expensive unit. Casual home theater setups, garage workshops, and karaoke nights all benefit from the mic input and FM radio, which feel like genuine extras rather than afterthoughts. If you are currently using a soundbar and feel like your speakers deserve more, this compact stereo amp is a logical and affordable next step that does not require rewiring your entire living room.

Not suitable for:

The Romicta BT-398 Stereo Amplifier is not the right tool for anyone who takes critical listening seriously or owns demanding, inefficient speakers that need sustained high-power delivery. The 60W per channel rated output is honest and functional for smaller rooms, but buyers expecting to fill a large open-plan space or drive floor-standing speakers at concert levels will hit the ceiling quickly and come away frustrated. Audiophiles who value component-grade build quality and want a metal chassis that feels reassuringly solid will find the lightweight plastic housing underwhelming. The Bluetooth connection, while clean in open rooms, is not reliable through walls — anyone planning to stream from a TV mounted across a large room may experience dropout that a wired connection would solve. Buyers expecting Dolby Digital surround decoding through the optical input should also look elsewhere, as this home audio amplifier handles PCM stereo only.

FAQ

Yes, the Romicta BT-398 Stereo Amplifier has a TosLink optical input that works directly with the digital audio output found on most modern TVs. Keep in mind it handles PCM stereo only — if your TV is outputting Dolby Digital 5.1, it will automatically downmix to two channels before the amp processes it, which is normal behavior for a stereo unit.

The 450W figure refers to peak power, which is a momentary ceiling the amp can briefly hit under ideal conditions. The continuous rated output is 60W per channel, and that is the number that matters for everyday listening. For small to medium rooms with standard bookshelf speakers, 60W per channel is more than adequate.

Yes, and this is one of the more useful features on the BT-398. The amp has separate outputs for passive speakers and an active subwoofer, so both can run simultaneously. The subwoofer's own gain knob controls its level since there is no dedicated sub-level control built into the amp itself.

In an open room, the connection holds well up to around 30 feet. Through walls or with obstructions, the range drops significantly — Romicta recommends staying within 15 feet when connecting to a TV or PC. If your source device and this compact stereo amp are in the same room with a clear line of sight, most users report stable, dropout-free playback.

Absolutely — the amp is rated for speakers between 4 and 16 ohms, so standard 8-ohm bookshelf speakers are right in the sweet spot. Most commonly available passive speakers in this category fall within that range.

There is a plastic insulation tab inside the remote's battery compartment that needs to be removed before the remote will function. It is easy to miss if you do not look closely. Pull the tab out, and the remote should work immediately.

It does run warm, particularly during longer listening sessions at higher volumes. This is normal for a compact class-D design. If you are placing it inside an enclosed cabinet or shelf with limited airflow, leave some space around the unit — at least a couple of inches on the sides and top — to avoid heat buildup over time.

Yes, the home audio amplifier has both a USB port and an SD card slot for direct file playback. It supports common audio formats like MP3. This makes it handy in settings where you want background music without needing a phone or streaming device connected.

For a typical one-car garage or a mid-sized basement, the 60W per channel output should be workable, especially with reasonably efficient speakers. Larger or more open spaces may expose the volume ceiling, particularly at higher impedance loads. If your garage is large and you want room-filling volume at high levels, you may eventually want something with more headroom.

The FM tuner performs well in urban and suburban areas with decent signal coverage — a physical antenna is included in the box, which helps considerably. In rural locations or areas with weak FM signal, you may get some static on certain stations and might benefit from an upgraded aftermarket antenna. The tuner itself is simple to use and does the job for casual background listening.
