Front Panel Features:

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 amplifiers stay cool thanks to their twin, forced-air cooling vents. 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.

3: Protection LED - This goes on for approximately five seconds whenever the SZ 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 . 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.

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 SZ Series and a distorted (“clipped”) signal is probably being output.

5: 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.

6: 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 . 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 SZ Series delivers full power output.

7: Power switch - Use this to power the SZ Series on or off. The internal LED lights whenever the SZ Series is powered on.

8: Security panel - The removable clear acrylic panel provides easy front panel access to the volume controls and helps protect against unwanted changes by unauthorized users.

Rear Panel Features:

1: Fan - This internal fan provides vital cooling to your SZ Series.Make sure that both the front and rear panel are kept free of all obstructions and that cool,fresh air is accessible at all times.Also,try to ensure  that the SZ Series is used in a dust-free environment.

2.) Euroblock Input Connectors - Connect incoming signals to these electronically balanced connectors.

3.) Limiter - Each amplifier channel has a quick attack limiter with peak detection to help ensure a clean signal.

4.) AC Input - Connect the supplied heavy-gauge 3-pin "IEC" power cable

5.) Euroblock Output Connectors - Use these to connect each channel of the SZ Series to 4-ohm or 8-ohm loudspeakers or to one of the 70 and 100 volt outputs if you are using a constant voltage system.
