Output Meters

The ART Pro Channel II provides both analog VU and LED level meters.
The analog VU meter displays the signal level various points of the processor depending on the
setting of the VU Meter Switches. "0" VU on the analog VU meter corresponds to +4dBu on the
balanced output.
The upper LED bargraph displays how hard the tube section is being driven (Warmth). The last two
LEDs in the meter are marked "Clip" indicating that the preamp section's gain is set too high.

VU Meter Switches

These switches allow you to monitor the level at the Preamp output, Compressor output, EQ section
or the Main output.
When both switches are out (POST/MAIN) the meter displays the output level at the Output jack of
the unit.
When the Pre switch only is depressed (PRE/MAIN) the meter monitors the EQ section output (Pre
output level control). The actual point that is monitored is After the EQ Bypass switch.
Depressing the Second switch allows you to see the levels before or after the Compressor. If Post is
selected the signal after the Compressor Bypass switch is displayed (the same signal present on the
Comp Out jack on the rear panel). Depressing the PRE and COMP switches select the output of the
Preamp section (the same signal present on the Preamp Out jack on the rear panel).
