Note: The speaker outputs, Pre-out and headphone outputs will all be muted. The Record outputs are unaffected.
Connections Loudspeakers Check the impedance of your speakers. When using a pair of speakers, you can use types with an impedance of between 4 and 8 Ohms. The red coloured speaker terminals are positive (+) and the black speaker terminals are negative (-). Make sure correct polarity is maintained at each speaker connector or the sound can become weak and “phasey” with little bass. Note: All connections are made using standard loudspeaker cable.
351A Speaker B connections The Speaker B connections on the back of the amplifier allow for a second set of speakers to be used (i.e. speakers located in another room). The Speaker B button on the front panel allows the second set of speakers to be switched on and off Note: When using two pairs of speakers, use speakers with a minimum nominal impedance of 8 ohms each.
