into the back of the amplifier, and then into the wall. Then turn the breaker switch on (up). The lights in your house will blink when the power supply charges the capacitors; this is normal. This magnetic breaker switch is not to be used as a safety disconnect during servicing and is not a substitute for unplugging the power cord.

On the front panel, the “Standby” LED indicator should be glowing blue, indicating that the power is on. The “Power” LED should not be on. If the “Power” LED is on, don’t get excited, just use the front panel stand-by button to go into stand-by mode, with the “Standby” LED on and the “Power “ LED off.

OK, so the amplifier is sitting there in stand-by mode with just the single blue LED lit. No speaker connected, as yet. You can go ahead and connect the source and speakers. Some speaker cables are very difficult to work with due to physical size and construction, make sure the speaker connections do not short together. It is recommended that you connect the speaker ends of these cables first.

Some powered subwoofers require an audio signal ground reference and their makers may suggest that a black speaker terminal is where this voltage reference might be found. On complementary designs, which would be typical of all power amps produced by Pass Laborato- ries™, this is an incorrect and unsafe assumption. On all Pass Labo- ratories™ power amplifiers a reference of 0 volts will be found only at pin 1 of the XLR input or at the shell of the RCA input.

Reference connections for these devices require special consideration when used with our product. If you have such a device, and wish to use it with our product, please contact our Foresthill, California fac- tory for specific instructions.... you have been warned.

The amplifier can be driven single-end or balanced, if driving the am- plifier single-ended, leave the supplied jumper in place (between pins 1 & 3 on the XLR). Your amplifier will operate without the jumper in place, but performance will be significantly diminished. You must choose either XLR or RCA inputs it is not advised to try and run both concurrently.

Now that the source component is connected, make sure there is no signal coming from it, probably by turning the volume all the way down.

With the speakers connected, push the front panel button to activate the amplifier. The “Power” LED will come on.
