4 Zone, 8 Channel Amplifier
D-Force describes the latest digital technology in amplifiers by Current Audio.
The D-Force amplifiers generate the equivalent analog output for speakers by using
a modulated audio signal rather than the traditional digital to analog conversion.
The amp is a Class D configuration (D does not stand for ‘digital’ but
merely refers to the next letter after Class C). It does exhibit a digital-like
output because the outputs are generated by turning the signal completely ON and
OFF
Features
Dual Power Mode - Input power is switchable from 110VAC to
220VAC.
3 Prong Plug - Grounded input power for Safety.
Master Power Switch - Rear panel switch to cut power for service
or hook-
up.
Multi-Stage Protection - Each pair of channels/zones is
individually protected with internal circuitry and is indicated on the front bi-
color LEDs. The amp will shut down a bad zone if it senses a short or is
overdriven. ONLY the channels that are affected will turn Off and indicates by the
LED turning from blue to red thus pointing to the channel in distress. The
remaining zones will run unaffected and continue to provide sound without shutting
down all zones.
AUX, Global and/or Individual Inputs – One input signal can be
universally distributed to all zones or the user can individually dedicate one or
more zones to have a unique separate input. The other zones will still play the
global input.
Gain Adjustments – There is a global gain control that sets the
maximum level to all zones. In addition, each zone has its own separate gain
control to allow the user to customize each zone to match the acoustics of that
room. This also sets the maximum loudness of each room.
Installer Friendly Connections – Each speaker channel has pull
off plugs to allow the user to make wire connections up to 14 gauge with positive
screw down terminals. The IEC power cord can be disconnected at the amp for easy
service. All inputs are made by easy connect gold plated RCA plugs.
Bridging – If more power is required for perhaps an outside
area, two channels may be combined (Bridged) to provide 140 watts at 8 ohms. This
is accomplished simply by a selector switch at each zone. CAUTION: Turn power off
when making change and always maintain an 8 ohm load when in the Bridge mode.
Rack Mount – packed with each amp is an accessory pack that
include brackets allowing the amp to be rack mountable. This is accomplished by
attaching the rack ears with the 4 included screws.
Power Mode – Power is toggled ON/OFF by the front power switch
and is indicated buy the corresponding LED. It can also be triggered ON/OFF by a
12 VDC signal on the rear 3.5mm Trigger in jack. Front Power button must be in
standby mode to operate trigger. LED must be red. The tip of the plug is (+).
