676 Quick Start Guide
1
Power down interconnecting equipment and make connections to the 676 (see
reverse side for connection diagrams).
2
Turn down the GAIN and POST TUBE ATTENUATION controls, connect the
included IEC power cable, then switch on the front-panel power switch. Now power on all
interconnected equipment.
3
Disable the EQ and Compressor/Limiter by disengaging the EQ ENABLE and
COMP/LIM ENABLE buttons.
4
If connecting a bass or guitar to the INSTRUMENT INPUT jack on the front panel,
engage the INSTRUMENT INPUT ENABLE button. If connecting to the MIC INPUT jack
on the rear panel, disengage the INSTRUMENT INPUT ENABLE button.
5
Engage the +48V button only if a condenser microphone which requires it is
connected to the 676. If connecting a ribbon or dynamic microphone, ensure the +48V
button is disengaged before connecting the microphone.
6
With source signal present, raise the GAIN control until the input PEAK LED lights
then lower it slightly so the LED goes out. If the PEAK LED lights when the GAIN control
is set very low, engage the 20dB PAD button then try again.
7
Raise the POST TUBE ATTENUATION control for the desired output level,
making sure not to clip the input on the next device. For cleaner tones, lower the GAIN
control and raise the POST TUBE ATTENUATION control. For warmer tones, raise the
GAIN control and lower the POST TUBE ATTENUATION control.
8
Engage the POLARITY INVERT button if required for the application. Engage the
80Hz button if the source signal does not contain useful content below 80 Hz.
9
To use the EQ, engage the EQ ENABLE button then adjust the EQ controls to
taste. If no EQ is required, leave the EQ ENABLE button disengaged.
10
To use compression and/or limiting, ensure you’re connected to the
COMPRESSOR / LIMITER output then enable the compressor/limiter with the COMP/
LIM ENABLE button and adjust the compressor/limiter settings to taste.
