1 LED METER
– 13-segment LED fader for each frequency
band, which can be software set for the centers fre-
quency and resolution.
2
FREQUENCY
LED
– Red LED indicating the frequency
that is displayed in the LCD display.
3 MASTER LED METER
-13-segment LED display for dis-
playing the main level.
4 LCD DISPLAY
– Backlit display that shows the various
parameters under control by the operating system.
5 DATA WHEEL
– Rotary encoder for entering parameter
values.
6 BYPASS
– When the red LED is on, the signal present at
the Inputs will be sent directly to the Outputs defeating
any DSP processing.
7 AUTO EQ
– Used to engage the automatic room equal-
ization feature when connected to a D2500 equalizer.
8
SOURCE
– Assigns the input of the RTA for either the
Left, Right, or
Left and Right
input to the LED Display.
9 GAIN
– This parameter is used to manage the operating
or reference level for the various function modes.
10 DETECT
– Selects the RTA to operate with either RMS
(average) or PEAK detection.
Controls and Functions
Front Panel Layout
11 INTER (INTEGRATION)
– Used in conjunction with
DETECT to adjust the RTA meter’s response time
from 15, 65, 250, 1000, 5,000 or 20,000 milliseconds.
12 WEIGHT
– Used to set an input filter curve with
either A, B, C or D weighted filters available.
13 REF (REFERENCE)
- Selects the display scale of
“DIG”, “+4u”, “-10V”, for digital maximum, +4 dBu and
-10 dBV.
14 RES (RESOLUTION)
-Selects the resolution of the
LED meters, which can be set to operate in a range
of 0.5, 1.0, 2.0, 3.0, or 6dB.
15 HOLD
- When set to ON the top LED on each band
will remain illuminated to assure that maximum
level can be recognized, and when AUTO is selected
the top LED stays lit then gradually falls.
16 FREQ (FREQUENCY)
-This parameter is used to set
the operating frequency for the various function
modes.
17 RTA
– When pressed, engages the LED lights indi-
cating that the unit is operating as a Real Time
Analyzer.
18 ANALYZE
– When engaged, the LED and the snap-
shot of the frequency response is held on the LED
display.
