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 tworackspace 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.
