EVI Audio GmbH products: Telex, Dynacord, ElectroVoice, Midas Consoles, KlarkTeknik and RTS. Arrangements are made with the dealer where you purchased the equipment from, for the returning of all unusable equipment at no cost, to the fac- tory in Straubing, for environmental protective disposal. -
Page 4: Introduction
DIGITAL SYSTEM AMPLIFIER 1 Introduction Dynacord‘s new high efficiency DIGITAL SYSTEM AMPLIFIER series combine uncompromising audio performance with the highest reliabilty. 1.1 Unpacking and Inspection Carefully open the packaging and take out the power amplifier. Inspect the power amp’s enclosure for damages that might have occured during transportation. - Page 5 DIGITAL SYSTEM AMPLIFIER that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: •...

2.5 Ventilation As with all Dynacord power amps with fan cooling, the airflow direction is front-to-rear, obviously because there is more cold air outside of the rack case than inside. The power amplifier remains cooler and dissipating the developing waste heat in a specific direction gets easier. -
Page 8: Selecting The Mode Of Operation (Mode)
The MODE switch on the power amp‘s rear panel defines how the audio inputs handle the input signals. The amplifier types DSA 8405 and DSA 8410 allow the configuration of audio inputs CH 1/CH 2 or CH 3/CH 4, the amplifier type DSA 8805 additionally allows configuration of audio CH 5/CH 6 or CH 7/CH 8. - Page 9 100 V 4 Ω 8 Ω 1000 W at 140 V (≈20 Ω) 1000 W at 200 V (≈40 Ω) DSA 8405 4 Ω 8 Ω 2000 W at 140 V (≈10 Ω) 2000 W at 200 V (≈20 Ω) DSA 8410 4 Ω...

Page 10: Selecting The Mode Of Output (Output)
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. -
Page 11: Variable Load Drive (Vld)
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. -

DIGITAL SYSTEM AMPLIFIER not affected by VLD. Power amplifier channels behave as described in chapter 2.7. The use of VLD considerably expands the adaptability of a power amplifier. Table 2.4 lists some application examples of VLD. 2 Ω 4 Ω 8 Ω... -
Page 13: Audio Cabling
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. -
Page 14: Operation
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. -
Page 15: Options
Control outputs (GPO's) allow the connection of external components, which, for example, are used to signal specific states to peripheral equipment. For further details about configuration, control and monitoring of amps with installed RCM-810 modules, please refer to the documentation of IRIS-Net. The latest version of IRIS-Net is available at www.dynacord.com. Owner‘s Manual... - Page 16 DIGITAL SYSTEM AMPLIFIER Controls and Connections Illustration 4.1: Controls and Connections of the RCM-810 1 INIT button The INIT button allows resetting the RCM-810 to factory settings. Press the button for at least 3 seconds using e.g. a small screwdriver. Table 4.1 lists the factory settings of the RCM-810 module. CAUTION: All RCM-810 parameters configured via IRIS-Net are discarded when pressing the INIT button.
- Page 17 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.
