Controls and Functions
1: Fan Vents - These vents allow air to escape the F1200 / F800 via the internal fan. Make sure that
both the front and rear panels are kept free of all obstructions and that cool, fresh air is accessible at all
times. Also, try to ensure that the F1200 / F800 is used in a dust-free environment.
2: Circuit Breaker - This circuit breaker will trip if there is a fault with the mains voltage or if maximum
output is exceeded (very highly distorted). Push it in (once only!) to restart the amplifier.
3: AC input - Connect the power cable to a grounded AC outlet.
4: Banana Plug output connectors - Use these banana plug outputs to connect each channel of the
F1200 / F800 to 4- or 8-ohm loudspeakers using speaker cable fitted with banana jacks. Be sure to con-
nect the loudspeaker correctly, with the red (+) terminal normally connected to the positive input of the
speaker and the black (ground) terminal normally connected to the negative input of the speaker. See
page 9 in this manual for more information about Bridged mode and pages 10 in this manual for full
speaker connection instructions.
5: Shrouded Binding Posts - Alternatively, you can use these to connect each channel of the F1200 /
F800 to 4- or 8-ohm loudspeakers using speaker wire. Be sure to connect the loudspeaker correctly,
with the red (+) terminal normally connected to the positive input of the speaker and the black (ground)
terminal normally connected to the negative input of the speaker. See page 9 in this manual for more
information about Bridged mode and pages 10 in this manual for full speaker connection instructions.
6: Input connectors - Connect incoming signal to the electronically balanced 1/4" TRS
(Tip/Ring/Sleeve) plugs, The TRS plugs are wired as follows: Tip (or Pin 2) hot, Ring (or Pin 3) cold, and
Sleeve (or Pin 1) ground. We recommend the use of balanced three-conductor cabling wherever possi-
ble (unbalanced two-conductor 1/4" plugs can also be inserted into these inputs, but you’ll get better sig-
nal quality and less outside noise and hum if you use balanced lines). The F1200 / F800 accepts input
levels of any strength but needs at least 0 dBu to achieve maximum power. Stereo signals should be
connected to both the Channel 1 and Channel 2 input jacks; however, when operating the F1200 / F800
in Bridged mode, use the Channel 1 input jack only. See page 10 and 11 in this manual for full intercon-
nection instructions.
7: Bridged / Stereo - For normal operation, place this two-way switch in its right (“STEREO”) position.
When placed in its left (“BRIDGED”) position, the signal arriving at the Channel 1 input only is again
routed to both power amplifiers (again, the Channel 2 input is ignored), but the two power amplifiers are
bridged together, providing a full 1200 watts of power into 8 ohms (in the case of the F1200) or a full 800
watts of power into 8 ohms (in the case of the F800). When in bridged mode be sure to follow the output
diagram on the rear of the amplifier and connect the loudspeaker correctly with the red (+) terminal from
Channel one normally connected to the positive input of the speaker and the red (ground) terminal from
channel 2 normally connected to the negative input of the speaker. For more information, see the
“Bridged Mode” section on page 9 in this manual and the “F1200 / F800 Connections” section on pages
10 in this manual.
WARNING: Due to the extremely high power output of the F1200 / F800 when
used in Bridged mode, be sure to use only loudspeakers sufficiently rated to handle the resultant
wattage (in Bridged mode, these must be 8-ohm speakers).
