This compact 2 input mixer which accepts either a line level signal or balanced microphone signal for each input. The output signal is suitable for feeding an amplifier with
either a line level input or balanced microphone input. Input one will vox mute input
2. Line level inputs and outputs are via stereo RCA sockets. Balanced microphone inputs and outputs are via 3 pin euro blocks. Any signal applied to input 1 will vox mute
any signal applied to input 2. This is regardless of the type of signal, ie line input signal feeding input 1 will vox mute a mic input signal feeding input 2. Volume controls
are provided for inputs 1 & 2 plus vox sensitivity. When vox is active a switched 24V
DC is provided via a 2 way euro block for controlling external devices ie: volume control override relays. Requires 24V DC power supply.
Features • 2 inputs to 1 output • Suitable for mic or line signals • Input 1 vox mutes
input 2 • Separate controls for volume and vox sensitivity • Vox operated 24V DC output
for control of external devices • Compact design • 24V DC operation via 2.1mm DC jack
(plugpack sold separately) • Dimensions: 25H x 105W x 81D mm
