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.
Make sure you use DI boxes to balance unbalanced signals; All incoming signals should be clear.
Make sure that the available voltage is not higher than stated on the rear panel.
Make sure that the power-cord is never crimped or damaged. Check the system and the powercord from time to time.
3
Make sure that the amplifier is turned down, before turning the power on or off. So you can avoid
supersonic frequencies, which could damage your speakers.
Don't put your equipment next to TV, radio, etc., because of interference or distortion.
If you connect other parts of the system, be careful of ground loops.
The best way to avoid ground loops is connecting the electrical system ground to one central
point ("star" system). In this case the mixer can act as a central point.
Before changing the ground, always turn off your amplifier.
Please read this manual carefully and keep it for future reference. Remember that the amplifier
has a better value on the market, if you save the carton and all packing materials.
Always operate the unit with the AC ground wire connected to the electrical system ground.
Connecting amplifier outputs to oscilloscopes or other test equipment, while the amplifier is in
bridged mode, may damage both the amplifier and test equipment.
Do not drive the inputs with a signal level bigger, than required to drive the equipment to full
output.
In system setup, the amplifier's output power must be 50%-100% more than the loaded
loudspeakers rated power.
Please turn off the power switch, when changing the power cord or signal cable, or select the
input mode switch.
In typical use, please set the volume at 0dB position.
Sometimes, when you want to send one signal to more than one amplifier, you should use a signal
distributor.
If your Dap Audio device fails to work properly, discontinue use immediately. Pack the unit
securely (preferably in the original packing material), and return it to your Dap Audio dealer for
service.
Allow time to cool down, before cleaning or servicing.
For replacement use fuses of same type and rating only.
Prevent distortion! Make sure that all components connected to the DSA have sufficient power
ratings. Otherwise distortion will be generated because the components are operated at their

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).
The maximum power current draw rating Is limited only by the front panel circuit breaker. Consult the
specification In the Appendices section for figures on the current that each amplifier will demand.
Make sure the mains voltage Is correct and Is the same as that printed on the rear of the amplifier.
Damage caused by connecting the amplifier to Improper AC voltage Is not covered by any warranty.
Unless otherwise specified when ordered. DAP audio amplifiers shipped to customers are configured as
follows:
North America 120VAC/60Hz
Europe 230VAC/50Hz
Asia 220VAC /50Hz/60Hz
Australia 240VAC/50Hz
South America 120VAC/60Hz or 220VAC/50Hz
Japan 1OOVAC/50Hz
NOTE: Always turn off and disconnect the amplifier from mains voltage before making audio
connections.
Also, as an extra precaution, have the attenuators turned down during power-up.
Cooling System and Requirements.
DSA Series amplifiers use a twin-tunnel forced-air cooling system to maintain a low, even operating
temperature. Drawn In by dual fans on the front panel, air flows through the cooling fans of the channel
heat sinks (dissipating power transistor heat), then exhausts through the rear panel slots.
IMPORTANT: To ensure optimum cooling, periodically clean the amplifier fan filters (removable
without tools). Also make certain that there is enough space around the front of the amplifier to allow
the cooling air to escape. If the amplifier is rack-mounted, do not use doors or covers on the front of
the rack; the exhaust air must flow out without resistance. If the amplifiers are housed in racks
with closed backs, allow at least one (1) standard rack space of opening In the front of the rack for
every four amplifiers.
Connecting Inputs.
Use the XLR input connectors on the rear to supply audio signals to your DAP Audio DSA Series amplifier.
The connectors accept balanced and unbalanced audio connections. (The TAS Series amplifiers are
configured standard with "Pin 2 hot" on XLR inputs. The Link connector can be used to loop the audio
Input to another amplifier Input. For more Information, see the section on Connection cables page 10.
Connecting Outputs.
Speakers are connected using Speakon connectors. For examples see figures 4, 5 and 6.

Mode Selection
The two-position, Mode Select switch (located on the rear panel) configures the amplifier for
either Stereo 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.
Fig. 4
Important !!!
Absolute minimum nominal load Impedance for stereo operation is 2 Ohm per channel.
Parallel Mode
When set to Parallel Mode, a signal applied to Channel A's input will be amplified and appear at outputs
of both Channels A&B.
Fig. 5
Important !!!
Absolute minimum nominal load Impedance for parallel operation is 2 Ohm per channel.
9
Bridged Mono Mode
Bridged Mono Mode straps both amplifier channels together to make a very powerful, single-channel
monaural amplifier. One channel "pushes" and the other "pulls" equally, doubling the power over that of
channel alone. Signal is applied to the Channel A input only. Both attenuators are used to control signal
level; in addition, both must be adjusted to the same setting. Only channel A input may be used.
Use extreme caution when operating the amplifier In Bridged Mono Mode. Never ground either side of
the speaker cable when the amplifier Is in Bridged Mono Mode; both sides are "hot. "If an output patch
panel is used, all connections must be Isolated from each other and from the panel.
Fig. 6
Important!!!
Absolute minimum nominal load Impedance for bridge operation is 4 Ohm.
Connecting amplifier outputs to oscilloscopes or other test equipment while the
amplifier is in bridged mode may damage both the amplifier and test equipment!
10
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.
