Setting Up and Using Your F1200 / F800
Setting up your F1200 / F800 is a simple procedure which takes only a few minutes:
1. Remove all packing materials (save them in case of need for future service) and
decide where the amplifier is to be physically placedN it can be used free-standing or
mounted in a standard 19" rack, requiring three rack spaces. When installed, make sure
the front, side and rear panels are unobstructed and that there is good ventilation around

the entire unit (we recommend the use of spacer panels, especially if multiple amplifiers

are used in a rack.

2. Set the rear panel Bridged / Stereo switch as desired (see the OBridged Mode� section
on page 9 in this manual for more information).
3. Make the speaker connections, using the banana or shrouded binding post output con-
nectors on the rear panel. It is never a good idea to power up any amplifier that is not
connected to loudspeakers. When operating in Stereo mode, any loudspeakers with a

minimum impedance load of 4 ohms (that is, 4 ohms or greater) can be used; however,

in Bridged mode, 8 ohm speakers must be used. Be sure to connect the loudspeaker
correctly. In Stereo mode, make sure the red (+) terminal is connected to the positive
input of the speaker and the black (ground) terminal is connected to the negative input ofMINIMUM LOAD IMPEDANCE

er. See page 9 in this manual for more information about Bridged mode and pages 10 in

4. Next, make the signal input connections, using either the balanced 1/43or RCA input
connectors on the rear panel (if operating the F1200 / F800 in Bridged mode, use theINPUTS

5. Connect the AC cable to a grounded AC socket. Because of the relay protection cir-
cuitry built into the F1200 / F800, you can even plug it into the same power strip that
other audio devices (such as a mixing console) are connected to. You can then turn on
all devices at once with the single power strip on-off switch, with no danger of damaging
connected speakers by generating Othumps.�
6. Press the front panel Power switch in order to turn on the F1200 / F800. The Power
LED will light LED will light.
7. Apply an input signal to the F1200 / F800 by gradually raising the output of the device
connected to the input of the F1200 / F800 until desired sound level is achieved observ-
ing the Peak LEDs. This is not a problem if the Peak LEDs light occasionally during peak
levels, but if it lights frequently, you may be overloading the F1200 / F800 and a distorted
(Oclipped�) signal is probably being output. If this occurs back off the Output Level control
of the device connected to the input of the F1200 / F800 until the LEDs light only occa-
sionally.
