Insertion Points
A balanced master insert point is provided on the back panel. This would be ideal to
use with a stereo compressor / EQ or dedicated mastering processor to give a complete
back end and mix down / mastering solution. An insert bypass button is also provided
on the front panel of the unit to quickly and easily A/B anything you do on the
additional outboard equipment inserted.
Output Gain.
This controls the level of the Ebony A4 output and the level of the summed signal.
The A4 Summer provides up to an additional 6dB of gain at the fully clockwise
position (10).
Metering
Two analogue VU meters are provided to monitor the output for the left and right
channels. Red peak LEDs are also present at the top of the unit above the VU meters,
these will illuminate at +22dBu on outputs at +4dBu nominal level, or +8dBu at
-10dBu nominal level, level can be switched using the buttons on the right hand side
of the front panel as mentioned above. The meter is also provided with a “+10dB”
switch, which keeps the reading on the scale when driving a high level out (to a DAW,
for example). In the +10 mode, 0VU is calibrated as +14dBu out.
