The PreSonus HP4 4 Channel Distribution Amplifier is a compact headphone amp that is perfect for monitoring with bands and artists in both live and studio settings. It is designed to be the ideal companion for studio engineers or bands using other PreSonus interfaces such as TubePre Comp16 and EQ3B.
The HP4 features four channels, each with its own dedicated volume potentiometer. The headphone outputs for each channel provide 130mW per channel, ensuring plenty of volume for even the most demanding players. It also includes a mono summing switch and a monitor mute switch for each channel. Additionally, the HP4 allows for daisy-chaining multiple units via the monitor outputs, providing added flexibility.
Whether used in a studio or during live rehearsals, the HP4 is perfect for bands and ensembles. It offers four high-powered stereo 1/4-inch headphone outputs, each with its own volume control. It also provides two balanced 1/4-inch line outputs (monitor outputs) and two balanced 1/4-inch line inputs.
Each channel on the HP4 features a mono summing switch and a monitor mute switch, allowing for easy control of sound output. This is particularly useful when communicating with band members or artists. Additionally, multiple units can be daisy-chained via the monitor outputs for even greater flexibility.
With 130mW per channel, the HP4’s headphone outputs deliver extremely high volume levels, perfect for demanding artists. The premium-grade circuitry ensures a wide dynamic range and pristine sound reproduction. Every nuance of the source audio is captured with exceptional clarity.
The HP4’s design is simple yet sleek, providing an effective way to process headphone channels. The controls are concise and allow for muting of the rear-panel Monitor outputs while keeping the headphone outputs active. The compact and robust construction makes it ideal for desktop use, and it can also be screw-mounted to a standard rack tray, taking up only 1/3 of a rack space.
The HP4 is built to withstand extensive daily use, with sealed and detented metal rotary controls. The unit comes with an external 16 VAC power supply.
