for increasing the overall output power. With a nominal level of +6dBu and a maximum level of +21dBu (8.7V) the output signal is electronically balanced. Output impedance is 100.. CONTROL PORT The CONTROL PORT offers two freely programmable control inputs and control outputs as well as the reference connections for ground potential and +5V. Using the PC Windows software IRIS, the control inputs can be configured and serve for instance for Power-On / Stand-by switching, preset switching or parameter control. The two control contacts IN1 / IN2 are internally set to +5V (open) via pull-up resistors. Activating the control inputs is possible by closing the contacts to ground potential (pin 3) via external switches, pushbuttons or relays. The two control outputs OUT1 / OUT2 are carried out as Open Collector Outputs. In non-active state (Off) they provide high ohmic resistance. In the active state (On) these outputs are connected to ground. The outputs serve for signalling internal operational states. They can be used for the direct triggering of LEDs, indication lights or relays. The +5V reference connector provides power supply for externally connected appliances with amperage of maximally 100mA. The control outputs allow signal indication of operational states (critical temperature, exceeding or decline of defined limit values, faults, etc.) at central operator desks or to other systems (fire alarm system, general alert system) even without PC. For further detail about configuring the control ports, please refer to the documentation accompanying the IRIS software. REAR VIEW RS-232 INTERFACE The RS-232 interface is for connecting media control systems as well as building management systems providing control and monitoring of all parameters. Communication is established via an easily to implement ASCII- protocol allowing trouble-free integration of Remote Amplifiers in media and touch panel control systems. For a programmer’s guide and complete protocol description, please refer to the documentation accompanying the IRIS software. ADDRESS The address selection switch allows setting the amplifier’s network address, which, within a CAN-network, can range from 01 to 250 (FA hex). Caution: Each address may exist only once within a network. Otherwise network conflicts might occur. Address setting has to be performed in hexadecimal code. The selection switch LOW represents the low-value digit while the HIGH-switch represents the high-value digit. Adress-Table: HIGH LOW Adress HIGH LOW Adress 0 0 Stand-alone 8 0 ... F 128 ... 143 0 1 ... F 1 ... 15 9 0 ... F 144 ... 159 1 0 ... F 16 ... 31 A 0 ... F 160 ... 175 2 0 ... F 32 ... 47 B 0 ... F 176 ... 191 3 0 ... F 48 ... 63 C 0 ... F 192 ... 207 4 0 ...

F reserved Address 0 (00 hex, factory-pre-set) ensures that the amplifier is separated from the remote communication, so that it does not appear in the system set-up even though it might be connected to the CAN-bus. When the amplifier is powered-on with its address set to “0”, all internal parameters are set to “0” respectively to bypass and the routing is set to 2-in-2. In that case the amplifier behaves absolutely linear, i.e. signal processing is deactivated. REMOTE CAN BUS Each amplifier employs two RJ-45 sockets for Remote CAN-bus connection. The sockets are parallel connected and serve as input as well as for connecting through of the Remote network. Common RJ-45 patch cables can be used for rack-shelf cabling. The CAN-bus needs to be terminated at both ends using a 120ohms termination plug. Detailed guidelines concerning cabling and bus length are provided in the chapter “REMOTE CONTROL NETWORK”. Both RJ-45 sockets additionally carry the balanced audio monitor signal. The nominal output level is +6dBu (1.55V) while the maximum output level is +21dBu (8.7V). Connector Pin-Assignment: (View of Contacts) REAR VIEW The STATUS LED provides optical indication of CAN-bus traffic. When the power amplifier’s address is set to “00” so that it is separated from the CAN- bus, the STATUS LED blinks every 3 seconds. When the power amplifier’s address is set between “01” and “250” and no CAN-bus activity has taken place yet, the LED blinks every second. As soon as CAN-bus communication is recognized, the LED is activated for at least 100ms whenever the power amplifier actively sends data on the CAN-bus.The STATUS LED may also be activated from the PC. In this case, the LED of the according power amplifier blinks fast and steady while all other status-LEDs within the system stay dimmed. This function is useful for optically monitoring communication and for quickly identifying particular power amplifiers in extensive system installations (please also refer to the IRIS software documentation). EASY REMOTE Easy Remote provides a simple way to remotely power-on/off the power amplifier. Th...
