Welcome to D-Force by Current Audio
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.
Because this amp uses pulse modulation, efficiency of these amps is 90%
compared to 50% of analog.
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, 115VAC or 230VAC.
•
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 channel is individually protected with internal circuitry
and is indicated on the front bicolor LEDs. The amp will shut down a bad channel if
it senses a short or is overdriven. ONLY the channel that is affected will turn Off and
indicates by the LED turning from blue to red thus pointing to the channel in
distress. The remaining channel will run unaffected and continue to provide sound
without shutting down both channels. Also, the amp has thermal protection.
•
Line Input
–
One input signal is distributed to the amplified speaker output. If a line
level loop output is required to power another amp use a dual output RCA plug.
•
Gain Adjustments
–There is a universal global gain control that sets the maximum
level to both channels. Set this to the maximum allowable speaker volume to
prevent the speakers from being overdriven.
•
Installer Friendly Connections
–Each speaker channel has gold plated screw
down 5-way binding posts to allow the user to make wire connections up to #12
gauge with either bare wire, spade lugs or banana plugs. 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, the two channels
may be combined (Bridged) to provide 280 watts at 8 ohms to one speaker. This is
accomplished by connecting the speaker output to both Red binding posts and
switching to the Bridged Mono mode on the back Bridged Switch.
CAUTION:
Turn
power off when making change and always maintain an 8 ohm load when in
the Bridge mode to avoid overheating the amp.
•
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 (+). A Master Power Switch
on the rear disables power to the amplifier for service.
