About Mackie HM-400

Because professional audio quality and versatility are paramount in studio and live performance settings, the HM-400 Rack-Mountable 4-Channel Headphone Amplifier stands out as an essential tool for audio engineers, musicians, and producers. Designed to meet the demands of both intimate home studios and larger practice spaces, this headphone amplifier is engineered to provide superior sound quality and flexible distribution options.

The HM-400 features a sleek 19" rackmount design, allowing for seamless integration into your existing audio setup. Its robust construction, characterized by a heavy-gauge steel chassis, ensures durability and reliability for continuous use. The long-wear potentiometers and switches further attest to the unit's ruggedness, promising longevity in the most demanding environments.

Equipped with premium analog circuitry, the HM-400 delivers an ultra-low noise floor and high headroom, ensuring that your audio remains pristine and clear at all times. This exceptional sound quality is maintained across all 12 headphone outputs, making it ideal for multi-listener environments where clarity is crucial.

Each of the four channels on the HM-400 boasts a dedicated main input with level control, as well as stereo outputs, auxiliary inputs, and customizable EQ settings. This allows for precise tailoring of the audio mix for each listener. The three headphone outputs per channel facilitate multiple connections, ensuring that each musician or listener has access to a personalized audio feed.

The auxiliary input on each channel comes with a balance control, enabling users to blend the main signal with an auxiliary source for a customized cue mix. This feature is particularly useful for performers who need to hear backing tracks or click tracks alongside the main mix.

For ease of monitoring, the HM-400 is equipped with 7-segment LED metering for each channel and the main input, providing visual feedback on signal levels at a glance. Users can also switch between mute and stereo/2-channel modes for each channel, offering additional control over the listening experience.

The inclusion of two 20' Heavy Duty 7mm Rubber XLR Microphone Cables with the HM-400 ensures that you have the necessary accessories to connect your gear right out of the box. These durable cables are designed to withstand the rigors of studio and stage use, providing reliable, noise-free signal transmission.

In summary, the HM-400 Rack-Mountable 4-Channel Headphone Amplifier is a versatile, high-quality solution for audio distribution. Its robust build, exceptional sound fidelity, and comprehensive feature set make it an indispensable component for any audio professional seeking to expand their headphone monitoring capabilities.
