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 The European model’s voltage can be adjusted from 220 V to 240 V.
l To avoid overheating, ensure sufficient air circulation is available both at the
sides and to the rear of the CF 200.
l Do not install any units sensitive to heat, for instance effects processors, directly
above the CF 200.
l Never expose the CF 200 to climatic extremes and ensure the amp is always
protected
from moisture.
l To protect your speakers, always switch the CF 200’5 power on last.
l 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.
(
4
)
GUITAR/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.

MAINS: The MAINS power switch illuminates when engaged.

REAR PANEL FEATURES AND FUNCTIONS
(
0
)
Prior to plugging the factory-included EUROMAINS CABLE in the AC receptacle
off
the
rear panel, adjust the voltage selector to the correct voltage.
(
7
)
Use a screwdriver to remove the FUSE BRACKET. Ensure replacement fuses hear
identical specifications to the originals. The fuse bracket on the European model
doubles as a voltage selector. Read the upright value to determine the correct
voltage
setting.
(
8
)
The GROUND LIFT switch severs the ground to the chassis, eliminating
annoying background hum when the power amp is used in conjunction with other
equipment.
(
9
)
SPEAKERS
Connect speakers to these jacks for stereo operation. When using one speaker
cabinet per channel, ensure each speaker has a minimum power rating of 100 watts
and an impedance between 4and 16 ohms. For two speakers per channel, each
cabinet must be rated at 8 ohms or greater.
(
10
)
SPEAKER PROTECT
Two fuses (3.15 A), one for each channel, protect speakers from damage due to
malfunctions e.g. direct current in the output jack. They also protect the power amp
from potential damage, e.g. due to a defective power cable.
Before resuming operation, ensure:
l you replace blown fuses with ones hearing identical ratings.
l both, the connected speakers and speaker cables are fully functional.
l a qualified repairman inspects he CF 200 for possible damage.

( 11 ) BRIDGE MODE
The MODE switch
(
12
)
determines whether the CF 200 operates in the 2 x
1
OOW
stereo mode, or in the 200W mono mode. To avoid accidental switching between
01‘
modes, a plastic
coverplate
is screwed in position. Ensure that the upper and
lower screws are never removed simultaneously. When the MODE
switch
(
12
)
is
in the MONO BRIDGE position, the CF 200 operates as a mono 200W amp. Use
the two binding posts to connect speaker cabinets. Ideally, use cables with
terminals or banana plugs. Minimum impedance: 8 ohms.
Black binding post: negative. Red binding post:
plus
The INPUT RIGHT and the VOLUME RIGHT control are activated in the
BRIDGE MODE.
(
13
)
INPUTS
The input jacks are suitable for
preamps
or mixers. Both channels automatically
amplify the signal if only the INPUT RIGHT jack is accessed. In the BRIDGE
MODE, only the INPUT RIGHT is
activated.
