1: Handle - For easy transport while carrying, or while rack mounting, the SX amplifier features two steel handles located conve-
niently on the left and right side of the front panel.
2: Fan Vent - The SX amplifiers stay cool thanks to their twin, forced-air cooling tunnels. Cool air is drawn through the front panel
fan filters, reducing the temperature of the internal components while forcing the heat out the rear vents. The fans will actually
sense the internal temperature and adjust their speed to maintain the optimum cooling conditions.
3: Signal LED - The front panel LED indicators continuously monitor the power output level for the corresponding channel. The
SIGNAL LED lights whenever output signal is present.
4: Peak LED - The PEAK segment lights whenever the channel is outputting signal at full strength. For the best signal-to-noise
ratio, the right (PEAK) segment should light occasionally during peak levels; if it lights frequently, you may be overloading the SX
Series and a distorted ("clipped") signal is probably being output. If this occurs and backing off the Input Level control delivers
too low an output level for your application, consider using Bridge mode (see the "Bridge and Parallel Modes" section on page 8 in
this manual for more information).
5: Channel input level controls - These 42-position detented controls allow you to precisely adjust the input level of the signal
arriving at the rear-panel input jacks (see #2 on the following page). At their fully counterclockwise position (labeled "MIN"), the
signal is attenuated by 80 dB (essentially completely off ). At their fully clockwise position (labeled "MAX"), the signal is at unity
gain (that is, no attenuation). When +4 dBu of signal arrives at the input jacks and the Channel input level controls are set to their
fully clockwise " 0 dB" position, the SX Series delivers full power output.
6: Protection LED - This goes on for approximately five seconds whenever the SX Series is powered on and then turns off (you'll
hear a "click" when it does so). The Protection LED will also light when overheating or other severe problems occur (see page 7
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 goes on, see the section entitled "The SX Series Protection Circuitry" on page
7 of this manual.
7: Power switch - Use this to power the SX Series on or off. The internal LED lights whenever the SX Series is powered on.
