OPERATION

When all connections to the amplifier are made, turn all rotary controls down and switch on the power and the power button LED will illuminate. Turn BASS and TREBLE controls to the 12 o’clock position (pointing straight up) and turn MASTER rotary control up part way for testing.

• Ensure a signal is being fed to one of the line inputs and gradually increase the volume control for that channel until the output is heard through the speakers. Turn up the MASTER to the maximum required volume level and reduce the channel volume control if necessary.
• Note: The initial test can be made using the built-in USB/SD audio player. The output of the amplifier is represented on the level meter LEDs. Anything longer than a short flash of this Clip LED may be indicating distortion or clipping of the output signal and the MASTER should be turned down.
• If a microphone is connected to MIC1 input, make sure it is switched on and if it requires phantom power, make sure this feature is enabled. Gradually increase its volume control whilst speaking into the microphone until the required volume level is reached.
• The microphone should not be able to “hear” the speakers, which can cause feedback (squealing or howling noise).

In addition to channel and MASTER volume controls, there are BASS and TREBLE EQ controls to adjust the tone of the overall output. At the 12 o’clock position, these controls are applying no effect to the signal (no boost or cut). Moving the BASS control clockwise boosts the low frequencies in the audio, whilst moving it anticlockwise will cut these low frequencies. Likewise, moving the TREBLE control clockwise boosts the high frequencies in the audio, whilst moving it anticlockwise will cut these high frequencies. Adjust these EQ controls to suit the type of audio signal or compensate for the room acoustics.

DIPSWITCHES

• Adjacent to the XLR line microphone input for each channel is a bank of 2 DIP switches.
• The left-hand switch is marked ‘Phantom’, which sets phantom power for the corresponding XLR connector. When this is switched on you can use a condenser microphone.
• The right hand DIP switch is marked mic/line. When this is switched on it enables to set channels to mic/line level. Noted: Be sure to make these DIP switch settings when the amplifier is switched off. Making any changes when the amplifier is powered up may cause loud bangs through the system which can damage the speakers.

SPEAKER OUTPUT

• For optimum performance, it’s important to use cables specifically designed for speaker use. Do not use shielded “guitar” signal cables for connection to these speakers.
• The low impedance mode of the PDS series speaker has a nominal impedance of 8Ω. If there is the need to connect multiple speakers in parallel, be sure to follow the amplifier’s specifications regarding the minimum allowed impedance. Most amplifiers allow for a minimum of 4Ω impedance, which would translate to two PDS speakers connected in parallel per side.
• Selection of the appropriate wire gauge is important for system operation. A cable that is too light will result in amplifier power being wasted due to the series resistance of the cable. In addition, loss of low-frequency performance may be experienced due to a degraded damping factor.

DC INPUT

• The PDC90 can be operated by 24V DC power for mobile applications (boats, fairgrounds etc.).
• For this type of application, connect the 24V DC power source to the 24V DC input terminals on the rear panel.
• 24 V DC Emergency alarm contacts terminal. If the fixed power supply fails, a mobile power supply can be connected to the 24V DC terminals to continue the power supply.

CONNECTING WITH BT 
Before transmission between your BT device and the unit is possible, both devices must be coupled. This process is called “Pairing”. The unit is served as a receiver, to receive the music stream to be played on the unit. If you have already coupled to a BT device before, this connection will be restored automatically when both devices are in range and BT operation has been selected on the unit. “Pairing” does not have to be repeated. This function may need to be activated in your BT device, however.

• Press [Mode] to enter BT mode.
• Turn on BT streaming on your device. The device will scan for pairable BT devices in the reception range.
• Select “PDC Amplifier” from the list with found devices.
• Start playback on your BT device. Playback now takes place emitting sound from the unit.

AUX IN 

• You can listen to the music stored in other audio device or smart phone via the unit, through the connection to the 3.5 mm aux-in jack on the front panel. Use a cable with 3.5 mm pins at both ends, one end connected to the aux-in jack on the unit, the other end  connected to the earphone jack on the audio device (or line out socket if available).
• Play music on the connected device, the sound will be emitted from the unit.

REPLACING THE FUSE

• If the fuse is defective, replace the fuse with a fuse of the same type and value. Before replacing the fuse, unplug mains lead. Procedure:
  • Step 1: Open the fuse holder on the rear panel with a fitting screwdriver.
  • Step 2: Remove the old fuse from the fuse holder.
  • Step 3: Install the new fuse in the fuse holder.
  • Step 4: Replace the fuse holder in the housing.
