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 sonic
improvements during the first week or so of operation.
1. ABOUT THE AMPLITUDE8m
1.3 IMPORTANT RECOMMENDATION
Before turning on your Amplitude8m, make sure you are using the right fuse in function of your local current :
• 20 Amp fuse for 120V (The 20 Amp fuse is installed by default).

2.1 ENVIRONMENTAL NOTICE
Here are very important instructions to follow before to power on your Amplitude8m:
I. It is imperative that the Amplitude8m be connected to a 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 powerline 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 be 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 Amplitude 8m, to protect it from
overheating, as well as the continued functionality of any equipment near and around it.
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 amplifer is connected, the amp goes into Standby. The amplifier is completely off, save for a
very small (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.
2.2 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.
