Compact 4-Channel Headphone Amplifier

The On-Stage FocusProAudio unit provides four independent stereo headphone channels from a single audio source. Each channel has its own volume control for personalised monitoring levels. A 12 V DC power adapter is included for immediate operation. The steel chassis and non-skid foam feet keep the device stable on a desk or stage.

Studios, podcasters and live ensembles

This amplifier suits recording sessions, podcast round-tables, rehearsal rooms and stage monitoring where several listeners share one mix. It is not intended for buyers who need individual channel EQ, built-in effects or wireless connectivity. Users requiring more than four simultaneous headphone feeds should look at larger distribution systems.

Plug into any line-level source

Connect laptops, phones, mixers or media players to the single ¼-inch stereo input on the front panel. Four front-facing ¼-inch headphone jacks feed the independent outputs. The external 12 V supply removes the need for internal mains circuitry, keeping the enclosure compact for portable rigs.

Questions about this item

What source device and cables are needed to feed audio into the ¼ inch input jack?

Any device with a stereo ¼ inch output — mixer, interface, phone via adapter — plugged into the single front input jack.

Can the four headphone outputs drive different impedance headphones at the same time without interaction?

Each channel has its own volume knob so listeners can set levels independently; the amp feeds all four jacks from one stereo signal.

How do I confirm the unit is powered and passing signal to all four channels?

The front power indicator lights when the 12V adapter is connected; turn each channel knob up to hear audio at that jack.
