Product Usage Instructions

1. Connect the power supply to the AC power source (AC100-120 V~/220-240 V~,50/60 Hz).
2. Ensure the power switch is in the “Off” position before connecting any audio sources.
3. For input A and input B, adjust the volume using the corresponding knobs.
4. If using a stereo signal, connect the RCA L/R (Left and Right) input connectors to the appropriate audio source.
5. If using a balanced microphone or line-level input, connect an XLR or 1/4″ combo jack to the corresponding input.
6. For balanced loop/mix output, use the balanced male XLR connector.
7. Adjust the impedance balanced loop gain according to your setup requirements.
8. Mount the speakers using the M10 x 6 rigging hardware or place them on a 35 mm pole socket.
9. The speakers can be angled at 0 or 10 degrees for optimal sound projection.
10. Ensure the speakers are securely mounted or placed on a stable surface.
11. When turning on the speakers, the power indicator should turn green.
12. If any protection features are triggered (thermal protection, low line voltage shut down, driver protection, DC and short protection), the amplifier will shut down automatically and reset once the issue is resolved.

REAR PANEL FEATURES

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 the 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 providing+/-10 dB of gain for each band.
6. Remote control: This Phoenix connector can be used to control the volume with an applied voltage.
7. 90 Hz 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. 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.
10. 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 MIX mode, this switch routes the combined (or “mixed”) signals of both INPUT A and INPUT B to the line level XLR OUTPUT jack.
11. 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.
12. XLR line level OUTPUT connector: This connector provides a balanced line level output for connection to additional Delta Active, powered subwoofers or amplifier.
