Initial power-up of the preamplifier
To power-up the Relentless Preamplifier, two switches are used. One is located on the back of the
power supply; this switch turns the AC power on so the power supply will be active. The other is the
Standby button located on the front of the preamplifier power supply chassis.
First, flip the switch on the back of the power supply to the On position. The Standby button
will illuminate. Press the Standby button on the front of the preamplifier. This will power up the
preamplifier, turn off the Standby button LED, and illuminate the volume indicators.
After power is switched on, the Relentless Preamplifier requires approximately 30 minutes to reach
optimal operating temperature. Although the preamplifier will sound excellent upon initial listening, the
sound quality will improve as it warms up to operating temperature.
Basic operation—Zone 1 operation
The Relentless Preamplifier front panel offers basic functions: Standby, Mute, Polarity, Zone 1 and 2
selection, volume, and source selection. The remote control adds additional controls detailed in the
“Remote Control” section.
Front panel control
Standby:
The Standby button is located on the front panel of the preamplifier. When the preamplifier
is in standby (off) mode, the LED in the middle of the button will be lit. Push the button to turn the
unit on. When power is on, the LED in the middle of the button will go off and the volume indicator will
illuminate. Push the button once more to turn the unit off. The light for the volume indicator will go out
and the LED in the middle of the Standby button will light up. The Relentless Preamplifier defaults to
Zone 1 and the Zone 1 LED will also illuminate upon initial turn on.
Mute: The Mute control disables the preamplifier output temporarily. Press it once to mute, and again
to restore the volume. When the sound is muted, the light in the volume indicator will flash. Mute is
independent for each zone when Zone 2 is also active.
Polarity: The Polarity control inverts the polarity of the entire system. While the Relentless
Preamplifier does not invert polarity, many source devices do, and many recordings are produced
with inverted polarity. Because there is no way of knowing what the proper polarity is, this must be
set by ear. Push the Polarity button on the on the front panel to invert the polarity. The lights on the
preamplifier’s front dial will turn from green to red when the polarity is inverted. Try listening with the
polarity normal or inverted, and use whichever setting sounds better. Depending on the recording, the
effects of polarity inversion are often subtle and sometimes even inaudible.
