WARNING
Do not expose this amplifier to moisture or excessive humidity, and do not use it outdoors. Fire hazard
may result.
The lightning flash with arrowhead, within an equilateral triangle, is intended to alert the
user to the presence of uninsulated “dangerous voltage” within the product’s enclosure
that may be of sufficient magnitude to constitute a risk of electrical shock to persons.
The exclamation point within an equilateral triangle is intended to alert the user to the

Contact Dan D’Agostino Master Audio Systems, LLC or your dealer if you have service needs.
Unpacking the Relentless Preamplifier from its case
While the preamplifier is still in its crate, please move it to a location near the place where it will be
installed. Remove all jewelry including watches, rings, and belts from your person to avoid damage to
the exterior of the preamplifier during the removal and installation. We recommend that two people
lift the Relentless Preamplifier.
The finish of the Relentless Preamplifier is durable, but it can be damaged if care is not taken. To
maintain the preamplifier’s pristine surface, we strongly suggesting wearing the supplied white lifting
gloves when handling to avoid abrasion, fingerprints caused by oils from skin, etc. See “Maintenance”
for instructions on cleaning.
Installation requirements
The Relentless Preamplifier’s three metal chassis makes it much heavier than the average preamplifier.
Make sure the surface that will support the Relentless Preamplifier can safely hold its weight.
Adequate ventilation must be provided for the preamplifier. There should two inches of clearance at
the top, and the bottom vents must not be obstructed by thick carpet, dust, etc. We recommend that
the preamplifier be installed in an open equipment rack to assure proper ventilation. The preamplifier
may be installed in a closed cabinet or in an equipment closet, but the cabinet or closet must be
designed with substantial ventilation at top and bottom; active ventilation (i.e., powered fans) is
preferred. Do not place the preamplifier directly on a carpeted surface.
If plugging the Relentless Preamplifier into a power strip or power conditioner, make sure it
is a high-quality unit that does not alter ground connections or insert current limiting elements in series
with the AC mains signal.
The Relentless Preamplifier transmits power and control signals through specially made connectors
mounted in the feet of each chassis. To assemble the preamplifier, place the audio chassis labeled
Relentless Preamplifier Audio Chassis—Right Channel Bottom
at the preamplifier’s final location.
Place the chassis labeled
Relentless Preamplifier Power Supply
on top of the bottom audio chassis.
Carefully ensure that the bottom plate connector makes solid contact with the audio chassis top plate
connector. Place the remaining audio chassis labeled
Relentless Preamplifier Audio Chassis—Left
Channel Top
on top of the power supply chassis. Carefully ensure that the bottom plate connector
makes solid contact with the power supply chassis top plate connector.
