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.
