The HP-112 headphone amplifier is designed with powerful, built-in internal power amps that produce a peak voltage equivalent to well over 100 watts per channel. This robust amplification ensures that the unit can drive up to four headsets simultaneously at any volume without distortion or signal degradation. Unlike many consumer-grade headphone outputs, the HP-112 provides a clean and detailed sound even at extreme levels, allowing musicians to hear their performance with clarity and impact.

The "SIM" (Stereo Image Manipulation) mode on the HP-112's stereo channels is a clever feature designed to enhance the listening experience for musicians. When engaged, this setting monos the bass frequencies of the stereo feed. This is particularly useful for reducing headphone fatigue and making the low end sound more focused and powerful, akin to listening to a full-range speaker system rather than a separated stereo headphone mix.

The multi-mode MUTE button on the HP-112 acts as a versatile "panic button" for seamless communication and control. It cycles through several modes: ON, MUTE (mutes the stereo signal), LEFT MUTE, and RIGHT MUTE. The left and right mute functions are particularly important for tracking, as they allow a musician to take one earphone off to listen to the room without sound from that channel leaking into other microphones.

Each HP-112 station is designed to drive up to four sets of headphones simultaneously. It features a robust built-in power amplifier and four parallel 1/4" stereo headphone jacks, allowing multiple musicians to monitor a single, custom-tailored mix with confidence and clarity.

The HP-112's multi-mode Talkback system, complete with a built-in microphone and talk button, is a powerful tool for streamlining communication between the control room and the musicians. It allows the engineer or producer to speak to the musicians without interrupting the recording process. The "TALK" mode lets them speak over the music, while the "INTERRUPT" mode momentarily kills the music to deliver a clear instruction or comment, making for a much smoother and more efficient recording session.

Yes, the HP-112 is designed for expandability. Multiple units can be daisy-chained together using ELCO multi-connectors, which are wired to ADAT standard. This allows for the creation of a comprehensive and scalable headphone monitoring system, providing every musician in a larger recording setup with their own personalized "more me" mix.
