Dnm Amplifier A-302U Bt

DNM A-302U BT Stereo Integrated Amplifier

The DNM A-302U BT is a stereo integrated amplifier from Indian brand DNM Audio, designed as a straightforward hi-fi hub for passive speakers. It delivers 45 W RMS per channel into 8 ohms and 75 W RMS per channel into 4 ohms, with a 20 Hz to 20 kHz frequency response. Around that amplifier core sits an unusually complete input set for its class: phono, two line inputs, USB, coaxial and optical digital inputs, Bluetooth and a front-panel MP3 input, plus outputs for two pairs of speakers, a line out and a record out. A remote control is included.

Key features

• 45 W RMS per channel at 8 ohms, 75 W RMS per channel at 4 ohms
• Bluetooth streaming for phones and tablets
• Phono input for a turntable, plus Line 1 and Line 2 inputs
• USB input and digital inputs on coaxial and optical
• Front-panel MP3 input and headphone socket
• Speaker A and B outputs for two pairs of speakers
• Bass and treble controls with a Direct switch to bypass them
• Line out and record out sockets, remote control included

Power for real speakers

With 45 W RMS per channel into 8 ohms and 75 W RMS per channel into 4 ohms, the A-302U BT drives typical bookshelf and floor-standing speakers to comfortable levels in living rooms, bedrooms and small commercial spaces. Total harmonic distortion is rated at 0.5 percent and the signal-to-noise ratio at 80 dB, with an input impedance of 47 k ohms and input sensitivity of 300 mV. Two pairs of speakers can be connected to the A and B outputs: play either pair on its own, or both pairs together when each pair is rated at 8 ohms impedance. That makes the amplifier practical for a main room plus a second zone, or for comparing two sets of speakers.

Analogue, digital and wireless sources

Source flexibility is the strength of this design. A dedicated phono input accepts a turntable directly, Line 1 and Line 2 take CD players, tuners and streamers, and a front-panel MP3 input gives a phone or portable player a quick wired connection. The USB input and the coaxial and optical digital inputs cover digital sources, while Bluetooth removes the cable altogether for everyday streaming from a phone or tablet. Input selection buttons on the front panel need a long press of three to four seconds to change source, a small quirk that prevents accidental switching. A headphone socket handles private listening without disturbing the room.

Tone control and signal routing

Bass and treble controls each offer 10 dB of boost or cut, and a loudness function adds +8 dB at 50 Hz and +4 dB at 10 kHz for fuller sound at low listening levels. When you want the signal left alone, the Direct switch bypasses the tone controls entirely. Beyond the speaker outputs, line out sockets can feed another amplifier or an active subwoofer, and record out sockets send the selected signal to a recording device. The slim 430 x 350 x 70 mm chassis with its simple, clean faceplate sits easily on a shelf or in a low rack space, and the amplifier runs on AC 230 V, 50 Hz mains.

Building a system around it

The A-302U BT suits a first serious stereo system or an upgrade for an older setup: add a pair of passive speakers and you can play records, stream over Bluetooth, connect a television through the optical input and listen on headphones at night, all through one box. The two speaker outputs also make it a sensible choice for small cafes, studios and waiting areas that need music in more than one space from a single amplifier.

If your sources are a mix of old and new — a turntable, a TV, a phone and a USB drive — the A-302U BT brings them together with adequate power, honest controls and no unnecessary complexity. It is a traditional integrated amplifier, specified and built for Indian homes and mains supply.
