3. Setup Guide
Follow these steps to properly set up your Behringer Europower PMP1680S powered mixer:
- Unpacking: Carefully unpack the PMP1680S mixer and ensure all components are present, including the rack mount brackets if desired.
- Placement: Place the mixer on a stable, flat surface or install it into a standard equipment rack using the provided brackets. Ensure adequate ventilation around the unit.
- Speaker Connections: Connect your passive speakers to the POWER AMP outputs using Speakon-compatible cables. Ensure correct impedance matching (e.g., 4 ohms for 1600W bridged mode). Refer to your speaker's specifications for optimal connection.
- Input Connections: Connect microphones to the XLR inputs (channels 1-8) and instruments or line-level devices to the 1/4" inputs. Activate +48V phantom power for condenser microphones as needed using the dedicated switch.
- Auxiliary Inputs: Connect external audio sources such as CD players, MP3 players, or tape decks to the CD/TAPE IN RCA inputs.
- Power Connection: Before plugging in, ensure all volume controls are set to minimum. Plug the power cord into a suitable AC outlet.
4. Operating Instructions
Familiarize yourself with the operational aspects of your PMP1680S mixer:
- Power On/Off: Locate the POWER switch on the front panel and turn it ON. The unit will initialize. Always turn on the mixer after connecting all inputs and outputs, and turn it off before disconnecting.
- Input Level Adjustment: For each channel, adjust the GAIN knob to achieve an optimal input level. The CLIP LED should only flash occasionally during the loudest peaks. If the signal is too hot, engage the PAD switch to attenuate the input.
- Equalization: Use the 3-band EQ (HIGH, MID, LOW) on each mono channel to shape the tone of individual inputs. The stereo 7-band graphic EQ on the main output allows for overall frequency correction of the mixed signal.
- Effects Processors: The PMP1680S features two independent 24-bit FX processors. Select desired effects using the PROGRAM knob for FX 1 and FX 2. Adjust the FX LEVEL to control the overall effect send. Apply effects to individual channels using the FX SEND controls on each channel strip.
- FBQ Feedback Detection: Press the FBQ button to activate the feedback detection system. Red LEDs on the 7-band graphic EQ will illuminate, indicating frequencies causing feedback. Reduce these frequencies using the corresponding faders to eliminate feedback.
- Output Modes: Select between STEREO (Main L/R), DOUBLE MONO (Main/Monitor), or BRIDGED MONO operation using the AMP MODE switch based on your speaker configuration and application needs.
- Voice Canceller: Activate the VOICE CANCELLER function for karaoke applications to reduce or remove vocals from stereo recordings played through the CD/TAPE input.
- Standby Function: Use the STANDBY switch to mute all microphone channels during breaks, allowing background music to play uninterrupted through the CD/Tape input without picking up stage noise.
5. Maintenance
Proper maintenance ensures the longevity and optimal performance of your PMP1680S mixer:
- Cleaning: Regularly clean the mixer's exterior with a soft, dry, lint-free cloth. Avoid using abrasive cleaners, solvents, or waxes, as these can damage the finish and internal components.
- Ventilation: Ensure adequate airflow around the unit to prevent overheating. Do not block the fan vents on the sides or rear of the mixer. Operate in a well-ventilated area.
- Storage: When not in use, store the mixer in a cool, dry place away from direct sunlight, excessive dust, and extreme temperatures. If transporting, use a protective case.
- Cable Management: Use proper cable management to prevent strain on connectors and accidental disconnections. Avoid bending cables sharply or placing heavy objects on them.
- Power Supply: Always use the original power cord provided with the unit. If replacement is necessary, ensure it meets the exact specifications.
6. Troubleshooting
Here are solutions to common issues you might encounter:
| Problem | Possible Cause | Solution |
|---|---|---|
| No Sound Output | Power off; incorrect connections; low volume; STANDBY engaged. | Check power, speaker, and input cables. Increase master volume and channel levels. Ensure STANDBY switch is disengaged. |
| Excessive Feedback | Microphone too close to speakers; high gain; resonant frequencies. | Activate FBQ Feedback Detection and reduce indicated frequencies on the graphic EQ. Reposition microphones or speakers. Lower gain. |
| Distorted Sound | Input signal too high (clipping); incorrect impedance; faulty cable. | Reduce input gain if CLIP LEDs are constantly lit. Check speaker impedance. Test and replace faulty cables. |
| Effects Not Working | FX SEND levels low; incorrect effect program; FX RETURN low. | Increase FX SEND levels on channels and FX RETURN levels. Ensure the correct effect program is selected. |
| No Phantom Power (+48V) | Phantom power switch off. | Verify the +48V phantom power switch is engaged for condenser microphones. |
