Connecting Your System
E. POWER REQUIREMENTS
Your STK VP-150 is pre-wired at the factory for the correct line voltage(120V or 220-240V) and is furnished
with the appropriate power cord and fuse. If fuse replacement is necessary, always use a fuse with the exact
type and rating as specified on the specifications page of this manual or as indicated on the unit itself.
F. FRONT PANEL INDICATORS
The front panel of the VP-150 has several indicators to alert you to the status of various operating conditions.
Knowing what these indicator LEDs are telling you will help you to use your STK amplifier.
1. Signal LED
A signal LED for each channel indicates that your signal level is so strong that there is distortion at the output
of that channel. While it is normal for the signal LED to flash during program peaks, the LED should not remain
constantly lit during operation. If it does, most likely you will hear the results in the form of distorted sound
that can be damaging to your speaker systems. In this case, reduce the signal level by lowering the input level
control for the channel that is clipping or reduce the level at the source.
2. Level Meter
A level meter for master stage indicates that your signal level supply to the power output.
If the clip LED constantly lit during operation, most likely you will hear the results in the form of distorted sound that can be
damaging to your speakers systems.
In this case, reduce the signal level by lowering the master level control for the main that is clipping or reduce the level at the
amplifier.
3. Power Indicator LED
The power indicator LED indicates that the power switch is in the on position and that AC mains power is applied.
