676
Quick Start
Follow these steps to get up and running fast:
1� Turn the GAIN and POST TUBE ATTENUATION controls all the way down and disable the EQ and Compressor/Limiter by
disengaging the EQ ENABLE and COMP/LIM ENABLE buttons.
2� 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.
3� Engage the +48V button if a condenser microphone which requires it is connected to the 676, otherwise, disengage the
button.
WARNING! If connecting a ribbon or dynamic microphone, ensure the +48V button is disengaged before
connecting the microphone to the 676.
4� Engage the INPUT METER SELECTION button to monitor input signal level on the VU meter.
5� With source signal present, raise the GAIN control until the input PEAK LED lights then back it off 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.
6� Raise the POST TUBE ATTENUATION control until the desired amount of output gain is achieved, 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.
7� Engage the POLARITY INVERT button if multi-miking a source and polarity inversion is required for matching polarity with
the other mic(s). Engage the 80Hz button if the source signal does not contain useful content below 80 Hz. See ‘The
Preamp Section’ on page 8 for additional information on these buttons.
8� Once microphone selection and position have been decided, enable the EQ with the EQ ENABLE button then adjust
the EQ settings to taste if any further tone shaping is required. If no EQ is required, leave the EQ ENABLE button
disengaged. See ‘The EQ Section’ on page 10 for further information on using the EQ.
9� Compression and limiting can be used to smooth out overly-dynamic source signals. If you wish to use compression
and/or limiting, you must be connected to the COMPRESSOR / LIMITER output. Enable the compressor/limiter with
the COMP/LIM ENABLE button and adjust the compressor/limiter settings to taste. For more information on using the
compressor/limiter, see ‘The Compressor & Limiter Section’ on page 12.
