Model PA4100X Page 3 GENERAL INFORMATION To enhance the ease of installation and obtain optimum performance from the PA4100X, we recommend that you first become familiar with all its features and special capabilities by studying the descriptions and instructions in this manual. The PA4100X was designed to meet the audio power amplifier needs of custom installed multi-zoned systems with high sonic quality and hi power output.
Page 4 Model PA4100X Auto Protection Circuit. This feature protects the PA4100X if a short or very low impedance is detected at the speaker terminals with each amplifier pair protected separately. Normal operation is restored automatically within 3 to 4 seconds after the short is removed.
Model PA4100X Page 5 PA4100X PANEL AND FEATURE DESCRIPTIONS 1. Front Panel. 17" X 5.25” panel designed for shelf mounting. The unit measures 6” high with the Feet (Item #5). When rack mounting use an adequate rack shelf mount making sure to allow for proper ventilation. 3 4 2 1 5 FIGURE 2 – THE MODEL PA4100X FRONT PANEL – FEATURES AND FUNCTIONS 2.

REMOTE MASTER ON/OFF and MUTE CONTROL (CI1 & CI2). These two Stereo Mini Jack connections allow each individual channel pair of the PA4100X to be powered ON and OFF and muted by a control voltage ranging between 5 and 30 Volts DC (11mA @ 12 V).
Page 8 Model PA4100X INSTALLATION - PHYSICAL LOCATION AND MOUNTING Upper shelf, component, wall, etc. PA4100X Keep perforations on top cover free of obstructions! To maximize air flow, route single large opening in lower shelf. Convection Airflow 2-inch spacing (minimum) Keep perforations on bottom plate free of obstructions. Figure 4 – HORIZONTAL MOUNTING When mounting the PA4100X, you should plan its location carefully. Pay close attention to each of the following factors: 1.
Model PA4100X Page 9 6. In multi-zone installations, you will have large bundles of wire and cable to accommodate audio, video and speaker connections. Be sure to allow enough strain relief for the leads and dress them in such a manner so as not to block airflow. 7. The PA4100X is designed for shelf mounting on flat horizontal surfaces. When mounting into a 19" rack, use an appropriate rack kit.
Page 10 Model PA4100X 3. The PA4100X 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 PA4100X to the corresponding "+" and "–" terminals on each speaker. This will ensure correct "phasing" - see Fig. 5 and Speaker Phasing below.

Be sure, in addition, to check other system components, such as preamplifiers, CD players, speakers, speaker wiring, etc., that may be at fault. PROBLEM PROBABLE CAUSE AND SOLUTION Rear panel Power Indicator does not light – no sound. Check line cord for good contact in a live AC outlet.
