“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.
More likely they’ll scream, “turn it down, you’re killing me!” Problem solved.
Now let’s solve “turn down that click.” The HP60 features two sets of line-level, stereo inputs that are routed to all six headphones; a Mix control that sets their relative levels for each headphone output. So you can feed the main control-room mix to channel A and the click to channel B and use the Mix controls to individually raise or lower the click relative to the main mix for each musician. Problem solved.
As for “more me,” in addition to the two pairs of main stereo inputs, you get an external stereo input pair with level control for each headphone channel. A Mono switch lets you sum the left and right inputs. Additionally, a mute switch is provided for each headphone output.
So you can send each person a feed of just their instrument or voice and can control the level separately for each. Problem solved.
Take Command
With the HP60, when you talk, everyone listens. Hit the Talk button and use the talkback-mic input and your favorite dynamic mic to tell ‘em what to do. You can even use a footswitch to control the talkback hands-free.
Each channel also has stereo line outputs that can send a copy of the line-level headphone-channel mix to additional headphone amplifiers or monitor systems. So if you have a large band and need more than six headphones, you can chain two or more HP60s.
