WARNING FOR YOUR OWN SAFETY, PLEASE READ THIS USER MANUAL CAREFULLY BEFORE YOUR INITIAL START-UP! Unpacking Instructions Immediately upon receiving this product, carefully unpack the carton and check the contents to ensure that all parts are present, and have been received in good condition. Notify the dealer immediately and retain packing material for inspection if any parts appear damaged from shipping or the carton itself shows signs of mishandling. Save the carton and all packing materials.
Only use system indoor, avoid contact with water or other liquids. Avoid flames and do not put close to flammable liquids or gases. Always disconnect power from the mains, when system is not used. Only handle the power-cord by the plug. Never pull out the plug by tugging the power-cord. Make sure you don’t use the wrong kind of cables or defective cables. Make sure that the signals into the mixer are balanced, otherwise hum could be created.
Connection with the mains Connect the device to the mains with the power-plug. Always pay attention, that the right color cable is connected to the right place. International EU Cable UK Cable US Cable Pin L BROWN RED YELLOW/COPPER FASE N BLUE BLACK SILVER NUL YELLOW/GREEN GREEN GREEN EARTH Make sure that the device is always connected properly to the earth! Return Procedure Returned merchandise must be sent prepaid and in the original packing, call tags will not be issued.
Description of the device Features The DSA-250, DSA-400, DSA-600, DSA-800 are professional high-end amplifiers : • Power rating DSA-250: RMS 2 X 25 0W (4Ω) , RMS 2 X 160W(8Ω) DSA-400: RMS 2 X 42 0W (4Ω) , RMS 2 X 2 8 0 W (8 Ω) DSA-600: RMS 2 X 600W[4Ω), RMS 2 X 4 0 0 W ( 8 Ω) DSA-800: RMS 2 X 750W[4Ω), RMS 2 X 500W(8Ω) • Features: Active clip limiting IMG impedance sensing Auto ramp protection Thermal protection Short circuit protection DC voltage protection Subsonic protection Switchable high/low/bypass f
Frontpanel Fig. 2. 1. Rack Mounting Holes. Two front panel mounting holes are provided on each mounting flange, 2. Fan Outlet Grills. DSA Series amplifiers are cooled by two, rear-mounted fans, Cool air flows over the heat sinks and exhausts through the rear grills, Make sure these outlets remain clear to allow unrestricted air flow, 3. Input Attenuators. Whenever possible, set attenuators fully clockwise to maintain optimum system headroom.
Backpanel Fig. 3. 10/11. Balanced 1/4" (TRS) &XLR Input Connectors. These connectors accept input signals on balanced TRS and XLR input plugs, See the figure at the right for information on polarity, Connectors for each channel are in parallel, The unused connectors may be used for linking other amplifiers. NOTE: Unbalanced "Tip/Sleeve" plugs may be used with the balanced TRS (Tip/Ring/Sleeve)connectors. The "ring" terminal or negative input will be connected to ground internally.
Operation Installation Remove all packing materials from the DSA. Check that all foam and plastic padding is removed. Secure the equipment into a 19" rack. Connect all cables. Connecting Power / Circuit Size Requirements. DSA Series amplifier power requirements are rated at: a)"idle" b) 1/8th power ("typical" music conditions) c) 1/3rd power ("continuous" music conditions) d.] maximum rated power (circuit breaker limited).
Mode Selection The three-position, recessed Mode Select switch (located on the rear panel) configures the amplifier for either Stereo. Parallel or Bridged Mono Mode. Amplifiers are factory-configured for Stereo Mode. Stereo Mode In Stereo Mode, both channels operate independently, with their input attenuators controlling their respective levels. Signal at Channel A's input produces output at Channel A's output while signal at Channel B's input produces output at Channel B's output.

Connection Cables Take care of your cables, always holding them by the connectors and avoiding knots and twists when coiling them: This gives the advantage of increasing their life and reliability. Periodically check your cables. A great number of problems (faulty contacts, ground hum, discharges, etc.) are caused entirely by using unsuitable or faulty cables.
Maintenance The DAP Audio DSA requires almost no maintenance. However, you should keep the unit clean. Disconnect the mains power supply, and then wipe the cover with a damp cloth. Do not immerse in liquid. Do not use alcohol or solvents. Keep connections clean. Disconnect electric power, and then wipe the DMX and audio connections with a damp cloth. Make sure connections are thoroughly dry before linking equipment or supplying electric power.
