AKG WMS 4000 HEADPHONE AMPLIFIER

MONITORING WITHOUT A MIXER

Integrating an HPA headphone amplifier into the WMS 4000 system makes life a lot easier for the FOH engineer. During the performance, the audio output signals of each receiver can be monitored directly, without having to

bother with an extra mixer. This feature proves an invaluable advantage, particularly if the WMS 4000 system and the mixer are located in different rooms, with the audio connection as a potential error source.

The HPA 4000 comes with eight jack inputs and one jack output for headphones. Channels can be routed to the headphone output using a rotary control. A clearly visible display indicates the currently active channel.
