other devices such as power amps. When the STP is on, the trigger outputs go high (+12V), when off they go low
(0V). If your unit locks up and doesn’t respond to anything, then chances are that the DC trigger input is applied,
but not assigned in the setup menu.

To properly set up the HT-Bypass feature you must complete the following. Make sure the unit is
powered up, but in the off position. Press in and hold the input up and down buttons while simultaneously
pressing the power button (volume knob). The display should come on in the setup menu. Press input up or
down until you find a screen that says “HT Bypass”. Once “HT Bypass” is selected, push the MUTE button.
This will select the HT Bypass mode, and allow for assignment. Now rotate the volume knob to turn HT Bypass
on and select the input desired for this operation. ((NOTE: Make sure you select the correct input in the set-up.
If the input is incorrect, and a signal is applied to that input when selected, the source will be playing VERY
LOUD.)) Now press the power button again to exit the set-up menu.
You can access the selected HT Bypass input any time by pressing the HT button on the remote, by
scrolling through the inputs on the front of the unit or on the remote, and also by using the remote trigger input.
Using the remote trigger input will automatically configure the preamp for use with an HT system, and also power
up connected amplifiers via the trigger outputs.

CAUTION: Disconnect the power cord or put the power switch in the off position before making any
connections to your preamplifier to minimize the risk of possible amplifier, and loudspeaker damage. Power up
your STP after all final connections have been made and checked.
The input and output connections you will find on the STP are made of nothing but the best. The RCA
(unbalanced) jacks are made with high quality gold plated copper, and should be properly connected with
interconnects of the same value. The Neutrik XLR (balanced) connectors are the finest balanced connector on
the market, and are the best possible option for connecting your amplifier to your preamplifier. When more
unbalanced inputs are needed, XLR to RCA adapters can be used. Please note that we don’t recommend using
the balanced outputs when using adapters on the inputs and not on the outputs. You should only use the adapters
when the unbalanced outputs are being used, and balanced outputs are connected with adapters. When using a
balanced input with an adapter, and balanced outputs, only half the signal will be present on the outputs because
the (-) phase on the input is shorted to ground through the adapter on the input of the preamp.
Using the new W4S power and interconnect cables would be a great way to ensure your system is closer to what
we call “our reference”. We are now offering superior cables at an affordable rate that anyone can afford. For
