Overview

The Langevin HP-112 12-Channel Headphone Mixer has many of the same features as the HP-101 8-channel model except there are 4 more mono inputs. Yes, the HP-101 8-channel units and the HP-112 12-channel units can be mixed in the same installation as far as the ELCO cabling is concerned however, the 8-channel headphone mixers won't receive signal channels 9-12 from the 12 channel units. (Duh.) All the rest of the functions (talkback, logic, Interrupt, Mic etc.) are 100% compatible between both models. See HP-112 ELCO pinout here.

The Langevin Headphone Mixer's Mute controls the Power Amps directly and steps through ON, MUTE, LEFT MUTE and RIGHT MUTE then back to ON. Each station also has bass and treble EQ controls carefully optimized for headphones. The master stereo volume control feeds the built-in power amps which produce peak voltage (equivalent to) well over a hundred watts per channel to drive up to 4 headsets at any volume the musician may choose. No weeny little beetles like you'd find in your Walkman here!

The two features that impress the musicians the most are the easy communication with one button and the fabulous sonic quality even at extreme levels. Ever clever, the ELCO connectors also provide pins used for several other communication and monitoring functions, including TALK and INTERRUPT. There are also hidden features on the ELCO's such as the ability for the control room to monitor each station's headphone mix or to hear the unswitched "always-on" individual station microphone.
