It also includes 2two balanced ¼-inch line outputs (monitor outputs and two balanced ¼-inch line inputs.

A mono summing switch is available for each channel, as well as including a monitor mute switch. This gives you the ability to easily kill the sound should you need to talk to your band/artists. You can even daisy-chain multiple units via the monitor outputs for added flexibility.

High-Volume Headphone Outputs

Each of the four headphone outputs provides 130 mW per channel, for intensely high volume levels for even the most demanding artist. The premium-grade circuitry delivers an extremely wide dynamic range. This results in pristine sound, that captures every nuance of your source audio.

Compact, Portable and Robust

The simple yet sleek design delivers a simple and effective way to process your headphone channels. The concise controls give you the ability to mute the rear-panel Monitor outputs, whilst leaving the headphones outputs active.

The compact yet robust construction is ideal for use on a desktop. It can also be screw-mounted to a standard rack tray, utilising only 1/3 of a rackspace. The high-grade components are sealed and detented with metal rotary controls that will withstand the rigors of extensive day to day use. The unit comes complete with an external 16 VAC power supply.
