REAR PANEL
1. AUX OUTPUT CONNECTORS (RCA): Further amplifiers can be connected from these RCA sockets.
2. AUX INPUT CONNECTORS (RCA): This stereo RCA input can be used to connect various audio sources.
3. SPEAKER TERMINAL: Speaker connections are provided as terminals on the rear panel. Wiring is described for several
types of speaker systems at “100V LINE SYSTEM”.
4. FM ANTENNA CONNECTION: Connection terminal for FM Antenna.
5. AC IN AND FUSE HOLDER: Socket for plugging in the supplied power cord (top). For instructions on how to change the
fuse (bottom), see “REPLACING THE FUSE”.
CONNECTING WITH BT
1. Activate the BT-function on your device (Mobile phone, tablet etc.) from which you want to play the
music. See the operating instructions for that device.
2. Press the “BT” button and activate BT-function.
3. Select “PDM 100V” on your BT-device and make the BT-connection
If password is required, you can enter "0000".
Attention: The BT distance is approx. 10 meter without any barrier.
100V LINE SYSTEM
For 100V line systems, connect the amplifier to the first speaker in the system using double-insulated speaker wire which has
adequate current rating to handle the total output of the amplifier.
Connect the “100V” output terminal to the positive (+) connection of the speaker and “COM” output to the negative (-)
connection of the speaker. Connect further speakers in parallel to the first speaker with all positive terminals and connected
together and all negative terminals connected together as shown below.
A 100V line speaker system can comprise of many speakers connected together. The determining factor for how many
speakers can be used on a single amplifier is the power rating. For most purposes, it is advised to connect as many speakers
as needed with a combined wattage of no more than 90% of the amplifier’s output power rating.
The terminals of a 100V speaker are connected to a transformer and in some cases, this transformer may be “tapped” for
different power ratings. These tapings can be used to adjust the wattage (and output volume) of each speaker in the system to
help achieve the ideal total power of the system for the amplifier.
SPEAKER TERMINALS
These terminals are offering 3 low voltage outputs 4Ω, 8Ω, 16Ω depending on your speaker combination. A 70V/100V
commercial output is also available.
Please note that one wire only should be connected to COM screw and one wire to the selected impedance or voltage.
ATTENTION: Multiple combinations cannot be done at the output level.
Four different types of connections are provided. The low impedance section: 4Ω, 8Ω, 16Ω is designed for a small amount of
speakers to be connected to your amplifier. The 70V/100V section is especially designed for a multiple speaker distribution.
When using the 70V/100V output, speakers have to be equipped with 70V/100V transformer. The maximum amount of
speakers to be placed on your distribution line is in relation to the power allocated to each speaker. The total wattage set on the
secondary side of the transformers on your speaker line must not exceed the maximum RMS output power: 30W, 60W or
120W. Failure to respect this may cause permanent damage to the amplifier.
