POWER
2
On/off switch. Upon switching on, the SIG and FX CLIP indicator LEDs light up briefly.
MIC CH
3
Microphone input with combined XLR and jack socket for connecting dynamic or condenser microphones. 48 V phantom power is always present at
the XLR socket. The microphone channel's jack socket is of a higher impedance than the XLR socket and is also suitable for microphones with a high
output level. Use the MUTE ALL button to mute the device before connecting or disconnecting a microphone.
4 INSTR CH INPUT
High-impedance instrument input with 6.3 mm jack socket. Use the MUTE ALL button to mute the device before connecting or disconnecting an
instrument.
INSTR CH INSERT
5
Series insert for the instrument channel. The insert socket facilitates the insertion of an external effects unit (e.g. phaser, flanger or chorus) to the
instrument channel. To do so, you require an insert cable with a 6.3 mm stereo jack plug on one end (Ring = Send, Tip = Return) and two 6.3 mm
mono jack plugs on the other end.
MIX OUT UNBAL
6
Unbalanced line output for connection to an instrument amplifier (6.3 mm jack socket). The signal is a mix of the instrument and microphone
channels.
7 MIX OUT BAL
Balanced line output with male 3-pin XLR socket. The signal is a mix of the instrument and microphone channels. This output is used with an XLR
microphone cable to connect the mixer to an active speaker, for example.
INSTR CH
8
Operating and display elements for the instrument channel.
GAIN – Controls amplification of the instrument signal. The corresponding SIG LED indicator lights up white when a signal is present. If the signal is 1
dB below the distortion threshold, the LED lights up violet. If the instrument input is driven beyond the distortion threshold, the SIG LED lights up red
and signal distortion may occur. Set the Gain control so that the SIG LED does not light up red when there are volume peaks.
TONE – 10 kHz high-shelf equalizer. In the centre position, the signal is unaffected. Turn to the left to reduce highs by up to 8 dB. Turn to the right to
increase highs by up to 7 dB.
FX SEND – Level control for mixing the instrument signal with the internal digital effects processor. Ensure that the red FX CLIP LED does not light up.
