DIGITAL SYSTEM AMPLIFIER ventilation. Since temperatures inside of the cabinet/rack case can easily rise up to 40 °C during operation of the power amp, it is mandatory to bear in mind the maximum allowable ambient temperature for all other appliances installed in the same cabinet/rack case. CAUTION: Blocking/closing the power amp’s ventilation louvers is not permissible. Without sufficient cooling/ventilation, the power amplifier may automatically enter protect mode. Keep ventilati- on louvers f

DIGITAL SYSTEM AMPLIFIER PARALLEL In PARALLEL mode, the inputs of channel A and channel B are directly electrically linked. The audio signal has to be applied to the input connectors of channel A. Using the input level controls to independently control the amplification of the two channels is still possible because only the channels’ inputs are linked. PARALLEL operation is the mode of choice, whenever the same input signal drives multiple power amp channels of a large system installation, e.g.

DIGITAL SYSTEM AMPLIFIER 2.7 Selecting the Mode of Output (OUTPUT) Different output modes are available for the amplifier‘s output channels. Each channel can be switched to high impedance mode (HZ) for driving 70 V or 100 V loudspeakers without output transformers (Direct Drive). In DUAL or PARALLEL mode each output channel‘s OUTPUT setting can be independently set. In BRIDGED mode for each pair of outputs only the OUTPUT setting of the channel with odd number (1, 3, 5 or 7) matters, the OUTPUT

DIGITAL SYSTEM AMPLIFIER 70 V Mode The 70 V mode allows connection of 70 V loudspeaker lines (Direct Drive) in high impedance mode (HZ) without using output transformers. In this case the maximum number of loudspeakers connected to an output channel is only limited by the amplifier‘s output power (500 W for DSA 8405/8805 or 1000 W for DSA 8410). This mode should be used if the distance between amplifier and speaker is larger than 50 metres (approx. 150 feet) and/or a high number of small speaker

DIGITAL SYSTEM AMPLIFIER 2.10 Audio Cabling Input Inputs are electronically balanced. Whenever possible, using balanced audio signal feeds at the input of the power amplifier is always preferred. Unbalanced connections should only be used if the cables are very short and no interfering signals are to be expected in the vicinity of the power amplifier. In this case, bridging the screen (shielding) and the pin of the inverting input inside of the connector is mandatory. Otherwise, a 6 dB drop in l

DIGITAL SYSTEM AMPLIFIER 3 Operation 3.1 Volume Control In DUAL and PARALLEL mode, the level controls LEVEL on the power amp’s rear panel are used to control the amplification of the corresponding channel. The scale values are given in dB. Turning the control to the right increases and turning it to the left decreases the volume. In BRIDGED mode operation, the output volume for a pair of outputs is only controlled by the level control of the channel with odd number (1, 3, 5 or 7), the setting o

DIGITAL SYSTEM AMPLIFIER 3 STATUS LED The STATUS LED is for monitoring the communication on the CAN bus. The LED blinks rhythmically every 3 seconds, when the module’s address is set to “00“, which means that it is disconnected from the CAN bus and software control. The LED blinks rhythmically in intervals of one second, when an address in the range of 01 to 250 has been assigned to the module and there has not yet been any activity on the CAN bus. As soon as communication on the CAN bus is re
