Front Panel controls
The Input Level Controls let the engineer set precisely, the operating level and balance
that will go through the equipment selected by the Insert buttons. The range is 10 dB in
0.5 dB steps.
The top row of buttons under ‘Functions’ select the following:
1.
‘IN 1-2’ selects which input is processed.
2.
‘S&M’ selects whether or not Insert 2 is in Stereo or Middle Sides mode.
3.
‘OUT MON’ selects whether the Monitor Output jacks have the Input or Output
signal sent to the monitor section.
The Input Monitor Offset level control adjusts the level of the Input Monitor. This is very
handy to match the input and output levels to listen to the effect of processing without the
level difference clouding one’s judgment. The engineer can also match input and output
level, look down at the scale, and determine the relative gain obtained from the mastering
process. This control has a scale of -2 to +8dB in 0.5 dB steps.
The S&M width control adjusts the stereo image width when the S&M button is pressed.
Please note that activating S&M without ‘Insert 2’ selected still passes audio through the
matrix.
The Output level control let’s one set the final level presented to the A/D converter. The
range is 10dB in 0.5 dB steps.
The level controls are all stepped attenuators for accuracy, repeatability, and highest
sound quality. The attenuators are built with what we feel are the highest quality switches
and resistors available at any cost. It is useful to
gently
‘run the switches through’ their
travel every so often to spread the lubricants around inside and wipe the contacts clean.
This helps keep the switches quiet. The use of contact cleaners is not necessary and will
damage the switches by washing the grease out.
