CONNECTING WITH BT

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.
Press the “BT” button and activate BT-function.
Select “PRM-AMPLIFIER” 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.

$Power-Dynamics-952-154-PRM-Series-100V-4Z-Mixer-Amplifier-USB-MP3-BT- $1$$

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.
