Stereo Mode Connections

1.Using good quality RCA-type patch cables connect the L and R OUTPUT jacks of the MRC88 Pre Amp Output or other driving preamp to the LEFT and RIGHT input jacks on the PA435X. Do this for each amplifier pair. Refer to Fig. 6.

2.Slide the MODE switch to the STEREO position.

3.Using good quality speaker wire, connect the individual speaker leads to the 4-terminal "SPEAKER" connectors on the PA435X as shown.

4.The PA435X is 4-Ohm safe in Stereo Mode. Make sure the impedance presented to the speaker terminals by the

speakers (or any combination of speakers) is 4-Ohms minimum.
