4. If you are using outdoor horn speakers, switch on the High

Pass Filter.

5. On the rear panel of the SZ Series, turn the input Adjust fully

counterclockwise (to the “-12dB” setting). Then connect the

supplied heavy-gauge 3-pin “IEC” cable to the rear panel IEC

connector and to any grounded AC outlet.

6. Press the front panel Power switch in order to turn on the SZ

Series. The Power LED will light and the Protection LED will go

on.

After approximately five seconds, the Protection LED will go off.

7. Apply an input signal to the SZ Series at or about +4dBu

(if sending signal from a mixer, drive the output meters at

approximately 0 VU). While the input signal is present, slowly

raise the Input Adjust control until the desired sound level

is achieved. The SIGNAL and CLIP LED indicators will show

you the continuous power output of the SZ Series as signal is

being passed. For the best signal-to-noise ratio, the SZ Series

should normally be run with the Input Adjust control at or near

maximum (fully clockwise, at the “0dB” position) and the CLIP

segments should light occasionally (but not frequently) during

peak levels. If you are using a mixer that has a master output

level control, 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 SZ Series, 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.

Setting Up and Using Your SZ Series

Setting up your SZ Series 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. Make the speaker connections, using the Euroblock 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 using the 4 ohm output, any loudspeakers

with a minimum impedance load of 4 ohms (that is, 4 ohms

or greater) can be used. Make sure the 4 ohm terminal is

connected to the positive input of the speaker and the COM

(ground) terminal is connected to the negative input of the

speaker. For 25 volt operation, connect the positive input of the

speaker to the 25 volt terminal and connect the negative input

to the COM (ground) terminal. For 70 volt operation, connect

the positive input of the speaker to the 70 volt terminal and

connect the negative input to the COM (ground) terminal. For

100 volt operation, connect the positive input of the speaker to

the 100 volt terminal and connect the speaker's negative input

to the COM (ground) terminal. See the Output Wiring Guide on

page 13 for more information.

3. Next, make the signal input connections, using the XLR

input connectors on the rear panel. If your mixer has balanced

outputs, we recommend the use of three-conductor cabling

and connectors (unbalanced two-conductor connections

can also be used, but you’ll get better signal quality and less

outside noise and hum if you use balanced lines). See the Input

Wiring Guide on page 12 for more information.

If you are using more than one amplifier, you can use the LINK

connector to the input of the second amplifer.
