When the optional IR sensor is installed, connect the PA 4000�s IR Remote Control Output a to the IR input jack on the rear panel of the component to be controlled. IMPORTANT: When a KP 1 is used with any channel on the PA 4000, DO NOT connect a remote sensor or other device to that channel�s Remote IR Sensor Input c unless you are using multiple, cascaded PA 4000 amplifiers and KP 1�s with IR sensors, as explained below. The PA 4000 will process and forward IR commands received from a Remote IR Sensor Input c or a Remote Keypad Input d in the order in which they are received. For example, when four KP 1�s with optional IR sensors are used with four separate channels and two rooms send an IR command to control the same AVR at the same time, the second signal received by the PA 4000 will be held until the first sender�s command has been forwarded to the AVR for processing. The PA 4000 is also capable of being used with compatible multiroom-equipped Harman Kardon A/V receivers, using the KP 1 commands to power the AVR�s multiroom output on or off, while controlling the volume using the PA 4000. To enable this feature, slide the PA 4000�s MR On/Off Command Switch b to the left so that it is over the word �ON.� You must connect the PA 4000�s IR Remote Control Output a to the IR remote input of the AVR in order for this function to work. Notes on Using KP 1 with Cascaded PA 4000�s: 1. When multiple PA 4000 amplifiers are cascaded together, each amplifier may use separate KP 1�s even though all are fed with the same audio source. Connect the KP 1�s to each amplifier as described above. 2. When IR sensors are used with multiple amplifiers, daisy-chain the IR Remote Control Output a of each PA 4000 to one of the Remote IR Sensor Inputs c of the PA 4000 immediately prior to it in the audio signal chain. However, note that if an IR command is transmitted simultaneously from any of the downstream amplifiers and from the KP 1 connected to the channel used for the Remote IR Sensor Input c, the two commands will be garbled. 3. When multiple, cascaded PA 4000�s are used with a Harman Kardon A/V receiver that has multiroom-control capability, it is recommended that you slide the MR On/Off Command Switch b for each PA 4000 in the system to the �OFF� position. Otherwise, when the last channel of any PA 4000 in the system is turned off, that PA 4000 will signal the AVR to turn off, regardless of the status of the other PA 4000�s in the system.
Setting Turn-On Volume Level Limits
The PA 4000 is equipped with a turn-on volume level limiter in order to prevent possible disturbances or damage to equipment. Normally, when any channel pair of the PA 4000 is turned on, it will play at the volume setting in use at the last listening session. However, the level will automatically be limited to either the factory-preset limit of �12dB, or to a user-determined limit. The KP 1 allows you to set or reset the volume level limit from the remote location. Two people are needed to complete this procedure, as adjustments must be made to the KP 1 and PA 4000 at the same time. 1. With source material playing, move the Power Control Mode Switch g for the channel being adjusted to the middle �MUSIC SENSE� position. 2. Use the KP 1 in the remote room to set the volume level to the desired turn-on volume limit � that is, the loudest desired turn-on level � by holding down the Power Button 3 while simultaneously adjusting the Volume Controls 4. 3. After releasing the keypad buttons, return the Power Control Mode Switch g for the channel being adjusted to the �ON/KEYPAD� position. To reset the Turn-On Volume Level Limit to the factory preset of �12dB: 1. With source material playing, move the Power Control Mode Switch g for the channel being reset to the middle �MUSIC SENSE� position. 2. Simultaneously press the KP 1�s Power and Volume vw Buttons 34. 3. After the KP 1�s buttons have been released, return the PA 4000�s Power Control Mode Switch g for the channel being reset to the �ON/KEYPAD� position.
Troubleshooting
If your PA 4000 is not responding to button presses of the KP 1: � Check the wiring for the cable connecting the KP 1 to the PA 4000. Make sure it is Straight Through T568B cable, as described in Step One. � Make sure the PA 4000 has been plugged in and is powered on. � Make sure that all audio components are properly connected to the PA 4000 and sending an audio signal to the PA 4000. � Make sure that a remote control is not simultaneously sending signals to an IR sensor that has been connected to the PA 4000�s Remote IR Sensor Input c for the same channel as the KP 1. If the component intended to receive commands from an optional IR sensor installed in the KP 1 is not responding: � Make sure that the component is plugged in and its master power switch is turned on. � Check the connections between the IR sensor and the KP 1�s IR Sensor Terminal Block ¢. � Check the connection between the PA 4000�s IR Remote Control Output a and the IR remote control input of the component to be controlled. � Make sure that another remote control is not simultaneously sending signals to an IR sensor connected to the PA 4000�s Remote IR Sensor Input c for the same channel as the KP 1.
Operation
Turn on the PA 4000 by pressing its power switch. This will cause the Standby indicator for the channel pairs selected using the Power Control Mode Switches g to light. Turn the PA 4000�s channel pairs on or off in response to presses of the corresponding KP 1�s Power Button 3. Adjust the initial reference output levels for your system using your receiver or preamp/processor�s controls. Do not use the Volume/Output Level Controls h on the back of the PA 4000. For subsequent listening sessions, you may raise or lower the volume levels in the remote listening location by pressing the KP 1�s Volume v or w 4 buttons. When an optional IR sensor has been installed, at any time during the listening session, point the transmitting end of the previously selected component�s remote control toward the sensor mounted in the KP 1, and press the remote�s buttons to transmit the desired command to the PA 4000, which forwards the command to the component. If your component is equipped with an IR remote output that is connected to one or more additional components, these may also be controlled using the sensor mounted in the KP 1.
