. GATE/THRESHOLD
This control adjusts the threshold level for the expander/gate section in the range of off to 10dBu. Signals below
the set level are attenuated.
. CHAN. ON SWITCH
This switch activates the corresponding channel. The switch is used to make direct A/B comparisons between
original material and processed signal.
. THRESHOLD CONTROL
This control sets the threshold point for the compressor section. It has a range of -40dBu to 20dBu.
. RATIO CONTROL
The RATIO control determines the ratio between the input and output level for all signals exceeding the thresh-
old point. The ratio range can be adjusted from 1:1 to 11:1 (Limiter).
. ATTACK CONTROL
The ATTACK control determines the rate by which the compressor responds to the signal which exceeds the
threshold. This control can be adjusted from 0.1ms to 200ms
6. AUTO SWITCH
By activating the AUTO switch, the ATTACK and RELEASE controls are disabled and the attack and release
rates are automatically derived from the program material. This function allows for unobtrusive musical com-
pression of signals or mixes with widely varying dynamics.
7. RELEASE CONTROL
The RELEASE control determines the rate that the compressor returns to unity gain after falling below the
threshold level. This control can be adjusted from 0.05s to 4s.
8. OUTPUT CONTROL
The OUTPUT control allows for the increase or decrease of the output signal by a maximum of 20 dB. Thus, a
level loss due to the compression or limiting process can be compensated for .
9. bbE ON/OFF SWITCH
This switch engages the BBE Process as indicated by the green LED. When in the "OUT" position the green
LED will not illuminate indicating that the BBE Process has been disengaged.
0. bbE PROCESS CONTROL
When the knob is in its minimum position, completely counterclockwise, no process is taking effect and the circuit
is in its noise suppression mode. Turning the knob clockwise will introduce the BBE Process. Adjust the knob to
mix the desired amount of process to suit your taste. Use the BBE as an extension of the tone controls. Generally
a good place to start the BBE process is to set the knob to it's 12 o'clock position, then adjust accordingly.
. bbE LO CONTOUR CONTROL
This control is a low frequency adjustment for the BBE Process. It provides a boost of 10dBu when turned to its
maximum position (clockwise) at 50Hz. When turned to its minimum position (counter-clockwise) no adjjustment
is taking place.
. INPUT LEvEL METER
Shows level of incoming signal in a range from -20dB to +6dB.
