  • Page 3: Important Safety Instructions

    IMPORTANT SAFETY INSTRUCTIONS The lightning flash with arrowhead symbol, within an equilateral triangle is intended to alert the user to the presence of uninsulated „dangerous voltage“ within the product’s enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons The exclamation point within an equilateral triangle is intended to alert the user to...

  • Page 4: Description

    DESCRIPTION Congratulations! With buying an Electro-Voice PRECISION SERIES power amplifier you have chosen an appliance that employs the most advanced technology. P-Series power amps combine outstanding audio performance, highest reliability and operational stability. Each power amplifier employs an RCM-24 Remote Control module allowing centralized configuration, control and monitoring of all relevant power amp parameters (like output current, output voltage, load impedance, etc.).

  • Page 5: Unpacking & Warranty

    DESCRIPTION Next to controlling and monitoring, the RCM-24 Remote Control module provides comprehensive signal processing functions. It includes a total of 20 parametric filter–, X-over functions, delays, routing and level control as well as compressors and limiters per channel. All parameters can be freely edited and stored in the module’s 8 user presets.

  • Page 6: Front View

    FRONT VIEW Use the POWER switch located in the centre of the front panel to switch the appliance’s power on. The soft-start function prevents current inrush peaks on the mains, which in addition prevents the mains line protection switch from activating during power-on operation of the power amplifier. The loudspeaker outputs are activated via relay switching with a delay of approximately 2 seconds effectively attenuating eventual power-on noise.

  • Page 7: Rear View

    REAR PANEL INPUT A / INPUT B This indicator lights as soon as the integrated dynamic limiter is activated and the power amplifier is driven at the clipping limit or generally at its maximum capacity. Short-term blinking is not a problem, since the internal limiter trims input levels of up to +21dBu down to a S/N-ratio of approximately 1%.

  • Page 8: Rs-232 Interface

    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.

    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”...

  • Page 10: Cabling

    CABLING NF-VERBINDUNGSKABEL 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.

  • Page 11: Network Examples

    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)
  • Page 12 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.

  • Page 13: Can-Bus

    CAN-BUS The CAN-bus allows using different data rates, with the data Baud Rate Bus Lenght rate being indirectly proportional to the bus length. Small 500 kbit/s 100 m networks allow baud rates up to 500kbit/s. 250 kbit/s 250 m For sizable dimensioned networks reducing the baud rate (minimum 10kbit/s) is necessary.
