FRONT PANEL DESCRIPTION
1. POWER switch.
It has been a tradition at Rane Corporation to say something clever about the
POWER
switch on all its
products. Certain government restrictions now eliminate our option of continuing this tradition. Pity.
2. POWER indicator LED.
This solid-state illumination device lights up to let the operator know Item 1 (above) is working
and the thing is plugged-in.
3. GATE/EXPANDER THRESHOLD control.
This rotary control allows the operator to set the input level below which the
Gate/Expander operates.
4. GATE/EXPANDER THRESHOLD LED.
This yellow LED illuminates any time the input signal falls below the threshold
level set by its neighboring knob to the immediate left.
5. GATE/EXPANDER RATIO control.
This rotary control determines the ratio to be applied to the Gate/Expander function.
Increased clockwise rotation increases the circuit slope. The full counter-clockwise position disables the Gate/Expander.
6. COMPRESSOR THRESHOLD control.
The position of this rotary knob determines above what input level the Compres-
sor functions. Full clockwise rotation disables the Compressor entirely.
7. COMPRESSOR THRESHOLD LED.
This yellow LED illuminates any time the input signal exceeds the level at which
the COMPRESSOR THRESHOLD control is set.
8. COMPRESSIOR RATIO control.
This rotary control determines the slope of the Compressor once it has exceeded the
indicated threshold. Full counter-clockwise rotation of the RATIO control disables all Compressor activity.
9. LIMITER THRESHOLD control.
This rotary control determines above what level the Servo Locked Limiter™ functions.
Full clockwise rotation of this knob disables all Limiter activity.
10. LIMITER THRESHOLD LED.
This LED illuminates any time the input exceeds the LIMITER THRESHOLD setting.
11. GAIN REDUCTION meter.
This five segment LED meter indicates the amount of reduction, below unity, being applied
to the audio signal by the VCA.
12. BYPASS switch.
When pressed in, this Channel in the DC 24 is is hard-wire Bypassed. Each Channel may be individually
Bypassed for comparison and alignment purposes. See OPERATING INSTRUCTIONS on page Manual-4.
13. OUTPUT LEVEL control.
This rotary control increases or decreases the output gain of each Channel by 12 dB. In the
center detent, gain will be unity.
(NOTE: Channel 2 OUTPUT LEVEL controls overall output in COMBINE mode.)
14. SIGnal present LED.
This LED illuminates any time the input signal exceeds approximately -40 dBu.
15. OverLoad LED.
This LED illuminates any time the output exceeds a level equal to -4 dB below the clipping level.
16. DUAL / SLAVE mode switch.
In the
in
(SLAVE) position, this switch causes both Channels’ Gate, Compressor and
Limiters to act together, i.e., they are “slaved.” All controls for both Channels remain active, so independent settings are
still possible; however, whenever a signal in one Channel exceeds its settings, then
both
Channels change by the same
amount. In the
out
(DUAL) position, both Channels operate independently.
17. CROSSOVER FREQUENCY control.
This rotary control selects the crossover frequency. What did you think?
