GENERAL DESCRIPTION

The Samson SZ Series amplifiers have been designed 
to provide robust, clean output with low distortion 
and wide dynamic range, along with the dependability 
demanded by the most professional design engineers 
and audio installers. The SZ1240 will deliver 240 
watts at 4 ohms. The amplifiers can also run at 25, 70 
or 100 volts thanks to its internal, high performance 
matching transformers, making it an ideal solution for 
Constant Voltage systems. 
The SZ1240 is enclosed in a convenient two-
rackspace chassis and features a reliable linear 
amplifier design. Rear panel controls include Input 
Level Adjust from –12 to 0 dB and a High Pass Filter 
at 400Hz to use with announcement horn speakers. 
A front panel Signal, Peak and Protection LED 
indicator helps you set the correct operating levels. 
Standard XLR Input and Link connectors, plus 
Euroblock speaker output connectors are provided to 
ensure easy connections and maximum flexibility. 
The SZ1240 employs internal wind tunnels with 
forced-air cooling via an internal fan, greatly reducing 
the chance of overheating and other thermal problems. 
Multi-stage protection for power-up, overheating, 
over-current, short circuit, low output impedance and 
DC voltage assures high reliability under the most 
demanding situations. 
The SZ1240 amplifier is road tough with its all steel 
chassis, 19-inch rackmount design and convenient 
carry handles facilitating easy installation in any rack.
Optimized for commercial installations including 
schools, houses of worship, office buildings and live 
sound venues, the SZ1240 amplifier will deliver clean, 
reliable power.

FEATURES

>

  Built-in 70/100 volt output transformers with flat 

frequency response from 70Hz to 18kHz provide 
constant voltage for distributed speaker systems.

>

  Rear panel level control allows precision adjustments 

from -12 to 0 dB.

>

  Clean, crisp sound - Impressive audio specifi cations 

such as 0.04% THD, dynamic range of 105 dB, 
crosstalk of 80 dB, and frequency response of 70Hz 
to 18kHz guarantee ultra-clean sound quality.

>

  LED signal indicators continuously display power 

output levels and allow you to correct for overloading 
(clipping) conditions.

>

  Forced air cooling via internal fan provides reliable 

performance without thermal and overheating problems.

>

  Protection circuitry (with dedicated LEDs) that guards 

against overheating or faulty wiring conditions.

>

  

 

Input connection is made using a standard male XLR 
connector to accommodate balanced signal sources.

>

  Output connections are made using Euroblock 

connectors which accept 12 gauge wire.

>

  The SZ Series can be mounted in any standard 19-inch 

rack (taking just two rack spaces), making it easy to 
integrate into any fi xed or traveling PA rig.

>

  The amplifi ers are enclosed in a ruggedly constructed 

(all-steel chassis with a sleek, black fi nish), standard 
2-space 19-inch rackmount unit.
