Setting Up and Using Your S1500 / S2000

Setting up your S1500 / S2000 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 three 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. If required, the supplied alternate PowerCon™

power receptacle should be installed in place of the IEC receptacle at this time.

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 S1500 / S2000 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 S1500 / S2000 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 S1500 / S2000, turn both Channel input controls fully

counterclockwise (to their “-80” setting). Then connect the supplied heavy-gauge 3-pin

“IEC” cable (or, if the alternate power receptacle is installed, a PowerCon™ cable) to the

rear panel power receptacle and to any grounded AC socket. Because of the relay pro-

tection circuitry built into the S1500 / S2000, 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 S1500 / S2000. 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 S1500 / S2000 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 S1500 / S2000 as signal is being passed. For the best

signal-to-noise ratio, the S1500 / S2000 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 S1500 or S2000,

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.
