Setting Up and Using Your S700 / S1000

Setting up your S700 / S1000 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 only two rack spaces. When installed, make sure that both the front 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 / Parallel switch as desired (see the “Bridged and Parallel Modes” section on page 7 in this manual for more information). If desired, use the XLR Link connectors to “daisy-chain” the output of the S700 / S1000 to external amplifiers (see #8 on page 4 in this manual for more information).

3.Make the speaker connections, using the banana or Speakon™ output connectors 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 or Parallel 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 or Parallel 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. See page 7 in this manual for more information about Bridged mode and pages 8 - 9 in this manual for full speaker interconnection instructions.

4.Next, make the signal input connections, using the Combination input connectors on the rear panel (if operating the S700 / S1000 in Bridged or Parallel mode, use the Channel 1 input only—see page 7 in this manual for more information). If your mixer or crossover network has balanced outputs, we recommend the use of three-conductor cabling and connectors (unbalanced two-conductor plugs can also be inserted into the Combo inputs, but you’ll get better signal quality and less outside noise and hum if you use balanced lines).

5.On the front panel of the S700 / S1000, turn both Channel input controls fully counterclockwise (to their “-80” setting). Then connect the supplied heavy-gauge 3-pin “IEC” cable to the rear panel IEC connector and to any grounded AC socket. Because of the relay protection circuitry built into the S700 / S1000, 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 S700 / S1000. The Power LED will light and the Protection LED will go on. After approximately five seconds, the Protection LED will go off (you’ll hear a click when this occurs).

7.Apply an input signal to the S700 / S1000 at or about 0 dBu (if sending signal from a mixer, drive the output meters at approximately 0 vu). While the input signal is present, slowly raise the Channel Input controls until the desired sound level is achieved.

The three-segment LED meters next to each Channel input control will show you the continuous power output of the S700 / S1000 as signal is being passed. For the best signal-to-noise ratio, the S700 / S1000 should normally be run with the Channel Input controls at or near maximum (fully clockwise, at the “0 dB” position) and the right (CLIP) segment should light occasionally (but not frequently) during peak levels. If you are using a mixer that has a master output level control (sometimes called “control room level”), use it to attenuate the signal as necessary to achieve the desired speaker level.

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.
