Hexacon

Professional 6-channel headphone amplifier

Introducing Nowsonic Hexacon

The Nowsonic Hexacon is a headphone amplifier with six separate amplifier channels. Each channel derives its signal from the stereo input on the rear panel.

If you need to temporarily feed a different signal to the connected headphones, you can replace the input signal via a direct input on the front. In addition, each headphone channel has its own stereo input for monitoring an alternative signal. Each output channel offers dedicated control over panning of the signal. Alternatively, the mixing ratio between the primary input and the AUX input can be controlled in the channel.

Each output channel features a dual-channel equalizer for optimizing the sound of the output signal as needed. For flexible wiring, the headphone outputs are in parallel as 1/4″ stereo TRS jacks on the rear and the front panel. Each channel can also be individually toggled between the four operating modes Stereo, Mono Left, Mono Right and Mono Left & Right for providing various monitoring options.

On the rear panel you will find balanced XLR and 1/4″ TRS jacks for the main bus. The input signal can be looped through to further Hexacon units via normalized THRU sockets (XLR – and 1/4″ TRS jack) for cascading. The output level is visualized clearly at all times via an eight-step level display for each channel as well as in the MAIN bus.

Reviews

“If you are looking for a Swiss army knife for headphone amplifiers, you should definitely test the Hexacon. Whether in the recording studio, for silent in-ear rehearsals or at trade fairs and presentations: The 19-inch dwarf feels at home wherever many headphones are to be used.”

“The Hexacon scores in all respects – for this price it is remarkably well equipped, flexible in the signal line, well adaptable in the sound, sound at the height as well as haptic and processing technically flawless.”

“The Nowsonic Hexacon is a good sounding headphone amplifier equipped with all kinds of special functions. For simple tasks like recording solo vocals, the Hexacon is almost unchallenged, but can already play out its possibilities well here. However, it only really gets going when it is fully occupied with up to 12 headphones, individual aux path recordings and the use of the equalizer. It is simply a good workhorse, which is especially suitable for those who regularly master larger recording situations with several participants.”
