We are pleased you chose the CF 200 power amplifier. Its innovative CURRENT
FEEDBACK circuitry is the ideal medium for the modern guitar rack. The CF 200
is equally suitable for PA, monitor, and keyboard applications.
PLEASE READ THE FOLLOWING GUIDELINES PRIOR TO OPERATING THE CF 200:
l
l
The European model’s voltage can be adjusted from 220 V to 240 V.
To avoid overheating, ensure sufficient air circulation is available both at the
sides and to the rear of the CF 200.
l
l
Do not install any units sensitive to heat, for instance effects processors, directly
above the CF 200.
Never expose the CF 200 to climatic extremes and ensure the amp is always
protected from moisture.
l
l
To protect your speakers, always switch the CF 200’5 power on last.
Service and repair work should be left to an authorized repair shop. Before
opening the housing, always ensure the mains power cable is unplugged!
FRONT PANEL CONTROL FEATURES
(
1 ) The VOLUME LEFT and VOLUME RIGHT knobs regulate input sensitivity and
subsequently the power output. In the BRIDGE MODE, only the right control is
activated.
The green -20 db LED ( 2
)
indicates the signal level at the respective input is
correctly adjusted. The red CLIP LED
(
3 ) denotes the signal level is too high, and
the CF 200 is clipping. Adjust the appropriate VOLUME knob so that the red LED
illuminates at impulse peaks only.

G UITAR/PA
The GUITAR/PA switch activates the CURRENT FEEDBACK circuitry (GUITAR mode
on, PA off). The CURRENT FEEDBACK circuitry elicits an amp, producing the
type of signal most desirable for guitar amplification.

stereo mode, or in the 200W mono mode. To avoid ac c idental switc hing between
modes, a plastic c overpla te is sc rewed in position. Ensure that the upper and
lower screws are never removed simultaneously. When the MODE switch

in the MONO BRIDGE position, the C F 200 opera tes a s a mono 200W a mp. Use
the two binding posts to c onnec t speaker c abinets. Ideally, use c ables with
