Samson POWER AMPLIFERS SZ1120 - Manual (Page 7)

SZ Series Layout - Front Panel
1: Handle - For easy transport while carrying, or while rack mounting, the SZ amplifier features two heavy
duty, die cast handles located conveniently on the left and right side of the front panel.
2: Fan Vent - The SZ series amplifers stay cool thanks to the forced-air cooling vents. Cool air is drawn
through the front panel fan, reducing the temperature of the internal components while forcing the heat
out the rear vents.
3: Protection LED - This goes on for approximately five seconds whenever the SZ Series is powered on
and then turns off. The Protection LED will also light when overheating or other severe problems occur
(see page 9 in this manual for more information). It is normal for the Protection LED to fade slowly when
the amp is powered off. When lit, no signal is provided to any connected speakers, thus muting them and
preventing any “thump” from occurring. For a complete description of the conditions under which this light
turns on, see the section entitled “The SZ Series Protection Circuitry” on page 9 of this manual.
4: CLIP LED - The CLIP segment lights whenever the amplifier is outputting signal at full strength. For
the best signal-to-noise ratio, the CLIP segment should light occasionally during peak levels; if it lights
frequently, you may be overloading the amplifier and a distorted (“clipped”) signal is probably being output.
5: Power switch - Use this to power the SZ Series on or off. The internal LED lights whenever the SZ Series is
powered on.
6: -20 dB LED - The -20dB LED lights whenever the output signal is 20dB below full power.
7: Signal LED - The SIGNAL LED lights whenever output signal is present.
