❖SPEAKER OUTPUT terminals
•Stereo Connections:
When you wish to use the unit as a stereo amplifier, stereo connections are used.
The speakers to be connected should have an impedance of 2Ω or greater. When
multiple speakers are to be connected, ensure that the combined impedance is 2Ω or greater for each channel.
•Bridged Connections:
When you wish to use the unit as a high- output monaural amplifier, bridged connections are used. (Make connections to the LEFT channel (+) and the RIGHT channel
The speakers to be connected should have an impedance of 4Ω or greater.
