1. Volume for input A and input B:
These knobs control the level of each input channel.
2. RCA L/R (Left and Right) input connectors:
These connectors allow input of a stereo signal (left and
right). The signal is actively combined or "summed" providing a mono signal to the amplifier.
3. GAIN selection switch:
This switch selects the proper gain structure for INPUT A. If a microphone is
connected to INPUT A, use mic mode
(up)
. If the signal source is anything other than a microphone
(playback device, keyboard or mixer output, for instance) use the line mode (down).
4. XLR 1/4" COMBO input jacks for INPUT A and INPUT B:
These convenient jacks allow XLR or 1/4"
balanced input connections to INPUT A and INPUT B.
5. HI and LOW EQ (equalization) controls:
These knobs control the equalization of the overall output signal
pro/-10dB of gain for each band.
6. Remote control:
This Phoenix connector can be used to control the volume with an applied voltage.
7. 90Hz Monitor filter switch:
Used to reduce bass buildup due to half space loading.
8. Front LED defeat switch:
Switches off the front power LED for discrete applications.
9 &10. POWER ON / OFF switch, POWER 'ON' indicator LED and LIMIT indicator LED:
The switch: Turns
the power on and off. The green LED to the left of the POWER switch illuminates when the power switch
is in the 'ON' position. The red LED illuminates when the signal limiter is limiting the level of the signal to
prevent distortion and overload.
11.Output source "LOOP/MIX" switch:
In the "LOOP" mode, this switch routes the signal of INPUT A and
B to the line level XLR OUTPUT jack, bypassing the EQ section and volume control. When in the
M
IX
mode, this switch routes the combined (or
"mixed")
signals of both INPUT A and INPUT B to the line level
XLR OUTPUT jack.
12.POWER cord receptacle:
This is a receptacle for a standard IEC, three prong, grounded AC electrical
connection cord. Be sure that you are plugging into the correct source voltage that matches what is
indicated just below the power cord receptacle.
13.XLR line level OUTPUT connector:
This connector provides a balanced line level output for connection to
additional Delta Active, powered subwoofers or amplifier.
