## Long description

Mentor Mackie HM-800 Black is a rack-mount headphone amplifier engineered for monitoring and playback in studios, live sound booths and broadcast environments. The unit provides low distortion monitoring with a THD of 0.005% and a clean noise floor with a signal-to-noise ratio of −67 dB. Housed in a compact 19" chassis, the HM-800 features a 6.3 mm headphone output and high input impedance to preserve source signal integrity. It is mains powered (220–240 V, 50–60 Hz) and includes the AC cable for immediate installation.
Advantages

Its 6.3 mm output and high input impedance make it compatible with a wide range of headphone models and professional line-level sources. The 19" rackable form factor and compact depth allow straightforward integration into studio racks and live setups while conserving space.
Suitable for
 Multitrack and project studios requiring reliable headphone distribution
 Live sound booths and FOH setups for cue mixes and monitoring

How to use
Install the HM-800 into a standard 19" rack space and secure it using the front mounting ears. Connect line-level sources to the amplifier's inputs and plug headphones into the 6.3 mm output jack. Apply mains power using the supplied AC cable and set the unit's output level to a conservative starting position before adjusting to the desired listening level. For multi-user setups, verify individual levels and balances to avoid excessive volumes and ensure consistent monitoring across users.
Usage recommendations
For consistent and noise-free monitoring, use low-noise balanced line sources when available and avoid running audio and power cables in parallel over long distances. When integrating into an existing rack, leave adequate ventilation space and position the HM-800 near other monitoring equipment for convenient access to headphone outputs.
