II. PANEL DESCRIPTIONS
RE 27 FRONT PANEL
RE 14 FRONT PANEL
1. EQ LEVEL CONTROL: This controls volume through the equalizer section and provides up to 6 dB
overall gain. Turn this control down if the overload LED lights up.
2. BYPASS SWITCH: Push this button IN to bypass the equalizer and level control; the bypass LED will
light whenever the bypass switch is engaged.
3. PINKNOISE SWITCH: Press this button IN toactivate the built-in pink noise generator. IMPORTANT:
SWITCH THE PINK NOISE GENERATOR OFF WHEN NOT IN USE, TO PREVENT POSSIBLE NOISE
BLEEDTHROUGH INTO PROGRAM MATERIAL
4. POWER SWITCH: You’ve probably figured this one out by now...
5. SIGNAL PRESENT INDICATOR: This green LED lights with any input above -20 dBm (.076 volts), even
in the bypass mode.
6. OVERLOAD INDICATOR: This red LED lights whenever the signal level through the equalizer section
reaches 4 dB below clipping
7. ANALYZER DISPLAY LEDs: Each red LED lights up when response is too high in that band; green LEDs
light when response is within ±3 dB or ±1 dB of the selected curve; yellow LEDs come on when response
is too low.
8. EQUALIZER SLIDERS: Calibrated in 3 dB increments, these sliders provide 12 dB of boost and 15 dB of
cut at each of the ISO frequency centers.
9. CURVE SELECT SWITCH: The NORMAL position will yield a flat response when all LEDs are green.
The HOUSE CURVE changes the response of the display such that the EQ sliders between 400 Hz and
1.6 kHz must be attenuated 3 dB to obtain green LED response. This reduction in midrange results in a
warmer more desirable sound at lower sound pressure levels.
10. WINDOW SELECT SWITCH: In the ±3 dB position, the green LED in each band will be lit when
signals of that frequency are within 3 dB above or below the Normal or House curve, whichever is
selected. In the ±1 dB mode, system response must be within 1 dB above or below the selected curve to
light the green LEDs.
