PreSonus HP60 6 channel Headphone Mixing System

“Turn my headphones up!” “More me, I can’t hear myself!” “Turn down that click!” It gets old. Change that tune with the HP60 headphone distribution system. The HP60 is more than just a half-dozen headphone amps, it’s a field-tested solution to a host of common headphone-monitoring problems.

Let’s start with “turn my headphones up.” Each of the HP60’s six headphone amps has its own level control and puts out 150 mW, which is loud enough to drive the alligators out of the Louisiana swamps. If they can’t hear this headphone system, they’re stone deaf.

The loudness of your headphones will vary depending on their design and their input impedance. The output impedance of the HP60 is 51 (ohms), and it will work fine with professional and consumer headphones but the volume will differ depending on which type of headphone you use.

Headphones with lower input impedances will generally be louder than higher-impedance headphones. (In this case, louder does not mean better!) Most professional headphones have impedances between 150 and 600. Consumer headphones for CD players and the like often have impedances between 8 and 32.

Broadcast headphones are specialized, and you are unlikely to use them with an HP60; their impedances are typically between 1.5 k (kilohms) and 2 k.
