Figure 5 - PA1235X Stereo Mode Connections

Figure 6 – Bridged Mode Connections

When making connections to the PA1235X be sure the power cord is unplugged. Proceed as follows:

Stereo Mode Connections

1.Using good quality RCA-type patch cables connect the L and R OUTPUT jacks of the driving preamp to the LEFT and RIGHT input jacks on the PA1235X. Do this for each amplifier pair. Refer to Fig. 5.

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 PA1235X as shown.

4.The PA1235X 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.

5.Be sure to observe correct polarity by connecting the "+" and "–" terminal from each channel on the PA1235X to the corresponding "+" and "–" terminals on each speaker. This will ensure correct "phasing". See Figure 5 and Speaker Phasing, following. Since the connectors are removable, you may unplug them for ease of lead assembly.
