SZ Series Features
The Samson SZ240 and SZ480 power amplifiers have been developed using the latest technology in Class D
power amplifier design. Here are some of their main features:
• Each SZ Series amplifier delivers 120 watts of clean power per channel at 70/100 volts and 4 Ohms, with
2 x 120 watts for the SZ240 and 4 x 120 watts for the SZ480.
• Class D amplifier operating at 85% efficiency using universal power supplies with power factor
correction and capable of operating from 100-240 V, 50 or 60 Hz. The SZ series amplifiers generate
virtually no heat and thanks to their low current draw, several SZ series can run off a single power outlet.
• Built-in 70/100 volt output transformers with flat frequency response from 40Hz to 20kHz provide
constant voltage for distributed speaker systems.
• Independent input level controls for each channel allow precision adjustments and the included
security panel provides protection from unwanted adjustment.
• Clean, crisp sound - Impressive audio specifications such as 0.04% THD, dynamic range of 105 dB,
crosstalk of 80 dB, and frequency response of 10 Hz to 25 kHz guarantee ultra-clean sound quality.
• LED signal indicators for each channel 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 relay circuitry (with dedicated LEDs for each channel) that guards against overheating or
faulty wiring conditions and also prevents “thumps” when powering on or off. This means that you can
use the SZ Series with a single power strip, into which a mixer or other audio devices are connected,
without danger of damage to connected speakers.
• Input connections for each channel are made using Euroblock connectors to accommodate both
balanced and unbalanced signals sources.
• Output connections for each channel are made using Euroblock connectors which accept 12 gauge
wire.
• The SZ Series can be mounted in any standard 19" rack (taking just two rack spaces), making it easy to
integrate into any fixed or traveling PA rig.
• The amplifiers are enclosed in ruggedly construction (an all-steel chassis with a sleek black finish),
standard 2-space 19-inch rack mount unit.
• Extended three-year warranty.
