1. ABOUT THE AMPLITUDE8M
1.1 GETTING TO KNOW YOUR AMPLITUDE8M
This Amplitude8m has been put through a rigorous and unique testing procedure that ensures
that it will last for many years with minimal service requirements. This procedure includes the
following:
●All assembled circuit boards are given a thorough visual inspection and are then tested
in a bench reference Amplitude8m.
●The tested, assembled circuit boards are then installed in a new Amplitude8m and the
whole unit is tested for every function and parameter.
●The unit is put on a burn-in torture rack to test for any possible component failures.
●It is then tested on an audio analyzer for all pertinent parameters.
●The unit has all remaining chassis components installed and then undergoes a
complete visual inspection, which assures that all Amplitude8m’s meet visual
specifications.
●The Amplitude8m then undergoes a critical listening and functional test.
1.2 BURN-IN TIME
While the Amplitude8m amplifier will sound wonderful without any burn-in time, users may
experience small sonic improvements during the first week or so of operation.
1.3 IMPORTANT RECOMMENDATION
Before turning on your Amplitude8m, make sure you are using the right fuse in function of your

2. OPERATION
Before turning on the Amplitude8m, ensure that all precautions and warnings have been
carefully reviewed and adhered to. Damage to the Amplitude8m caused by improper operation,
wiring and/or ventilation will not be covered under warranty and Trinnov Audio will not be liable
for any consequential damage or loss.
When the amplifier is connected, the amp goes into Standby. The amplifier is completely off,
save for a minimal (and low power) supply to power the soft-start circuit. When the Standby
button is pressed, the soft-start sequence begins and the LED turns green. Several relay clicks
may be heard while the amplifier readies itself for operation. When the turn-on sequence is
complete the LED will illuminate blue and the amp will be fully on. Pressing the Standby button
again takes the amp directly into the
standby mode.
2.1 ENVIRONMENTAL NOTICE
Here are critical instructions to follow before you turn the power on your Amplitude8m:
I. It is imperative that the Amplitude8m be connected to the ground via its three-wire AC
power cord. It is important that the AC power outlet, which the Amplitude8m is plugged
into, is actually grounded. Failure to do so will severely compromise the performance,
reliability, and safety of use of the Amplitude8m.
II. Ventilation is an important issue when placing the Amplitude8m in a system. Make
certain that the Amplitude8m is placed in a well-ventilated area or rack unit.
III. Please take note that some power line conditioners defeat the AC power ground on
their outlets. If the intention is to plug the Amplitude8m into a line conditioner, check
with your dealer to make certain that the particular conditioner that is intended for use
DOES NOT DEFEAT THE AC GROUND on its AC outlets. Only the highest-powered line
conditioners should be considered for use with the Amplitude8m. Otherwise, the
amplifier’s power output may be compromised.
IV. DO NOT remove any cover panels from the Amplitude8m, as there are no user
serviceable components inside. Refer servicing and updating to qualified service
personnel only.
V. It is imperative that the Amplitude8m be operated in a well-ventilated environment
and the immediate external temperature is maintained as specified in Appendix B of
this manual. External cooling fans may be required in some cases. Do not stack any
equipment directly above or below the Amplitude8m, to protect it from overheating, as
well as the continued functionality of any equipment near and around it.
11

2.2 REMOTE TRIGGERS
Use the remote trigger to connect to a compatible preamplifier, source device or other product
with 5 to 12 VDC output.
When so interconnected, the Amplitude8m will turn on and off in response to the signals
received from the source device. The trigger circuit requires a steady-state signal. Units that
send a pulse signal for turn-on and turn-off will not work with the Amplitude8m.
The trigger output will pass through the steady-state signal received on the trigger input to
switch downstream devices on and off.
NOTE: Make sure to use a mono TS mini-jack cable for 12V triggers
