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 placed— 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 “Bridged 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 of the speaker. In bridged mode make sure to follow the diagram on the rear of the amplifi- er. See page 9 in this manual for more information about Bridged mode and pages 10 in this manual for full speaker interconnection instructions.

4.Next, make the signal input connections, using either the balanced 1/4″ or RCA input connectors on the rear panel (if operating the F1200 / F800 in Bridged mode, use the Channel 1 input only— see page 10 and 11 in this manual for more information). If your mixer or crossover network has balanced outputs, we recommend the use of three-con- ductor cabling and connectors (unbalanced two-conductor plugs can also be inserted into the RCA inputs, but you’ll get better signal quality and less outside noise and hum if you use balanced lines).

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 “thumps.”

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 (“clipped”) 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.

If you encounter difficulty with any aspect of setting up or using your S700 or S1000, contact your local Samson dealer. If purchased in the United States, you can call Samson Technical Support (1-800-372-6766) between 9 AM and 5 PM EST
