component and attach the emitter to the sensor window after removing the protective paper cover on the flat side of the emitter head. A common IR jack is also provided for connection to other auxiliary devices.

Sense Input Connections

The sense input connection will typically be used to sense the power state of a source component using the Xantech CSM1 Current Sense Module. Plug the 3.5mm miniplug from the CSM1 into the appropriate sense jack. Be careful to match the source audio and video connection number on the BXAUDIO4X4 to the sense jack number. The CSM1 plugs into an AC power source. The component power cord plugs into the CSM1.

CSM1 Threshold Adjustments

a.Manually turn the component ON first.

b.Using a small (1/8” wide) blade screwdriver, rotate the current control to a full counter-clockwise position.

c.Rotate the control clockwise until the Threshold Adjustment LED goes OFF.

d.Manually turn the component OFF

e.Rotate the control until the Threshold Adjustment LED just goes ON.

f.Set the control to a point midway between these two settings. This should be the correct setting. NOTE 1: If the Threshold Adjustment LED does not go ON and OFF with the component power mode, make minor adjustments to the threshold adjust until the LED is in proper sync.

NOTE 2: Program IR commands fro BXAUDIO4X4 Controller current sensing as described in

“PROGRAMMING POWER MANAGEMENT”.

Zone Wiring Connections at the BXAUDIO4X4 Controller/Amplifier

In typical applications, each zone will have at least one BXAUDIO4X4 Keypad and a pair of stereo speakers. In those zones with both audio and video, at least one video monitor or television will also be used. In order to make these connections, the minimum requirement is home runs of one CAT5 cable for each zone’s keypad(s), two pairs for each pair of speakers, and one coaxial cable for a TV or monitor from each zone to the BXAUDIO4X4 Controller/Amplifier location.

Speaker Connections

1.Using good quality speaker wire, connect the individual speaker leads to the 4-terminal "SPEAKER" connectors on the BXAUDIO4X4 as shown in Figure 3.

2.The BXAUDIO4X4 is 4-Ohm safe. Make sure the impedance presented to the speaker terminals by the speakers (or any combination of speakers) is 4-Ohms minimum.

3.Be sure to observe correct polarity by connecting the "+" and "–" terminal from each channel on the BXAUDIO4X4 to the corresponding "+" and "–" terminals on each speaker. This will ensure correct "phasing". Since the connectors are removable, you may unplug them for ease of lead assembly.

4.As a rule of thumb, use 18 gauge speaker wire for speaker runs up to 30' (9m), 16 gauge up to 70' (21m), and 14 gauge up to 150' (39m). The 4-terminal connectors accept wire sizes up to 12-gauge max.

5.Strip the insulation back about 1/4" (6mm) and twist the strands on each lead to prevent fraying.

6.Speaker Phasing: To obtain stable imaging and full bass response, it is imperative that stereo speakers be connected "in phase" with each other. You can verify this as follows:

a)If the "+" (positive) and "–" (negative) terminals on your speakers are correctly marked, and visible, and you have wired the system with the positive connector on the rear of the BXAUDIO4X4 Controller/Amplifier connected to the positive connector on the speaker and the negative connector on the rear of the BXAUDIO4X4 Controller/Amplifier connected to the negative connector on the speaker, then the system will be "in phase". No further action is required. Most manufacturers identify the positive terminal with a red binding post, a "+" sign, or a red dot.

b)If you are unsure of the markings, you can verify the phasing. Using a mono sound source, such as AM

radio, alternately reverse the leads to one of the speakers. Pick the connection that delivers a solid center image between the speakers as well as best bass response.

CAUTION: After lead ends are inserted and the screws tightened down, be sure there are no free strands that could cause shorting!
