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.
