When connecting loudspeaker systems, please mind the polarity according to the following diagram: GROUND-LIFT SWITCH The ground-lift switch allows eliminating noise loops. If the power amplifier is operated together with other equipment in a 19“ rack-shelf, setting the switch to its GROUNDED position is recommended. If the power amplifier is operated together with appliances with differing ground potentials, setting the switch to its UNGROUNDED position is recommended. REAR VIEW LIMITER The integrated limiter provides reliable protection against signal clipping and has a switchable time constant. Leaving the switch set to SLOW is recommended for general use (factory pre-set status). When using the power amplifier as Mid/Hi power amp employed in active multi-way systems, setting the limiter switch to FAST is recommended. When using the power amplifier as low-frequency woofer power amp employed in active multi-way systems, setting the limiter switch to SLOW is recommended. BRIDGED MODE Switch for changing from normal (stereo) operation to bridged mode. In bridged mode the integrated power amplifiers operate in „push-pull“ operation. The output voltages of cannel „A“ and channel „B“ are doubled and present at the BRIDGED OUT connector. Channels „A“ and „B“ work phase-shifted in push-pull operation and may not be used as loudspeaker outputs. CABLING LF-CONNECTION CORDS Choosing balanced cables (two conductors for the audio signal plus separate shielding mesh) with XLR-type connectors is recommended for LF-signal connection. Although connecting unbalanced cables to the power amplifier inputs is possible as well, using balanced cabling is always preferable. A great number of today’s audio appliances employ balanced outputs. With balanced cabling, the shield connects all metal enclosure parts and thus efficiently eliminates the introduction of noise and hum. XLR-type connector pin-assignment XLR (male) XLR (female) REMOTE CONTROL NETWORK The network of the remote power amps is based on the CAN-bus standard, which for years is especially popular in automotive, industrial and security applications. The CAN-bus is a balanced serial interface for command and data transmission. Controlling the power amplifiers is performed from a PC with IRIS – Intelligent Remote & Integrated Supervision – software installed. The UCC1 USB-CAN Converter serves as interface between the PC and the CAN-bus. Connecting up to 100 power amplifiers per CAN-Bus with a maximum total cable length of 1,000 meters is possible. An additional CAN-bus is needed for controlling more than 100 power amps while the IRIS software allows administering a total of 250 power amps. The network topology used by the CAN-bus is the so-called “bus or line topology”, i.e. all participants are connected via a single two-wire cable (Twisted-Pair cable, shielded or unshielded) with the cabling running from one participant on the bus to the next, allowing unlimited communication among all appliances included. In general, it does not matter whether a participant on the bus is a power amplifier or a UCC1 USB-CAN converter, so that both – UCC1 and the PC as well – can be inserted at any position. Incorporating several UCC1 and PCs on a single CAN-bus is also possible. A total of up to 100 appliances can be operated on a single CAN-bus. Since the CAN- interfaces of all appliances are galvanically separated from the rest of the circuitry, network cabling also carries a common ground conductor (CAN_GND) ensuring that all CAN-interfaces in the network are connected to a common ground potential. The UCC1 provides the possibility for switching the CAN-ground to circuit-ground. Each participant on the bus system has two RJ-45 connectors for the Remote CAN-bus. These sockets are connected in parallel to serve as input and output (for connecting through) for the data transfer of the remote-network. The CAN-bus has to be terminated at both ends using 120. terminator plugs, two of which – CAN-TERM 120. – are supplied with the UCC1. Connect one of these to the RJ-45 socket of the first and the other to the socket of the last appliance on the CAN-bus. NETWORK EXAMPLES The following diagrams show examples of the data-bus wiring for different order of size: System with 5 amps and one UCC1 / PC at the beginning of the bus Terminators at the UCC1 (first unit on the bus) and at amp 5 (last unit on the bus) System with 2 amp-racks and an UCC1 / PC in the middle Terminators at amp 6 (first unit on the bus) and amp 12 (last unit on the bus) NETWORK EXAMPLES System with several amp-racks and several UCC1 / PCs UCC1s anywhere on the CAN-bus Terminators at amp 10 (first unit on the bus) and amp 16 (last unit on the bus) Next to the CAN-bus signal, network cabling also carries the balanced monitor audio signal for monitoring the power amp inputs and outputs. This monitor-bus allows software-controlled monitoring of the input and output signals of all power amps that are included in the remote netw...
