TRU Audio TRU-S350xi User manual

Caution, before using:
MAKE SURE TO READ THIS INSTRUCTION
MANUAL BEFORE TURING THE POWER ON
OR HOOKING UP THIS POWER AMPLIFIER.
Never expose the amplifiers to any kind of moisture. This piece
should NOT be used near bath tubs, sinks, wet basements or
swimming pools. Also avoid placing this unit by heat sources such
as radiators, heat registers or stoves.
Make sure this unit is not in direct sunlight.
Before connecting any cables to the amplifier, make sure the
power is OFF.
When deciding on where to place the unit, make sure there is
plenty of air flow. Do not set other components directly on top
of the amplifier. If other components must be place on top of
this piece, make sure to use some kind of spacers. If it will be
installed into a cabinet, make sure this is proper air flow. Adding
an additional cooling fan might be necessary. DO NOT remove
the feet from these units.
Make sure the speakers that will be connected to this unit can
handle the output power of the amplifier.
We suggest NOT using any kind of extension cord unless it is also
polarized and made from heavy gauge wire. If at all possible, plug
this unit directly into the wall outlet or surge protection.
General information and features:
Power Switch: This is used to turn the unit on or off.
LED Indicator: There is one LED indicator located on the
front panel, to indicate power on and active state. When first
turning the power on, LED will turn red and then turn blue once
the channel as been cleared. The LED’s will remain blue under
normal use.
12V trigger: need connect to and be controlled by the 12V
trigger out of the input source
Volume Level Control: this know adjusts the volume level
for the amplifier.
Line Input: This LFE high-level RCA type input jack is the
audio input for the amplifier. This gets connected to the "sub out"
from a processor, preamp or receiver. We suggest using a good
quality RCA patch cable for the best performance. The RCA input
is labeled “LFE IN".
Speaker Terminals: These binding post connections are
used to connect the speaker to the amplifier.
this should be set on 100-120V and 220-240V. For other countries,
please check the voltage requirements before plugging in the unit.
2-Conductor AC Cord Receptacle: A standard male
receptacle that fits a 2-conductor power cord.
Speaker phasing:
To obtain proper phasing and correct bass response, it is necessary
that all channels be in correct phase. The “Correct Phasing” occurs
when speakers move in and out in unison (in phase) on mono
audio. Speakers connected in phase ensure proper imaging while
an out-of phase connection causes indistinct imaging. Identify
the Positive (+) and Negative (-) on the speaker cable being used.
Make sure the Positive terminal of the speaker is connected to the
Positive terminal of the amplifier. Do the same with the negative
and then follow the same with all channels.
Amplifier connection:
Always turn off the power of your amplifier, processor/preamp and
all input/playback units before any connections are made.
Before turning your amplifier and processor/preamp back on, make
sure your volume is turned all the way down.
Remember the cooling issues mentioned earlier in this manual.
Improper air flow will reduce the life of the amplifier.
When deciding on the final location, keep in mind there needs to be
adequate space behind the amp to fit the speaker cables and patch
cables.
General maintenance and service:
The front panel is finished with a high-grade anodizing process to
make sure it maintains the flawless appearance. Occasionally wipe
off any dust build up with a damn, soft cloth.
DO NOT use any kind of cleaning solution or cleanser on these
units.
In for some reason the amplifier needs to be repaired, please
contact us immediately. We will issue a “Return Authorization
Number” (RA#) for return. This unit should not be shipped back
to TRUAUDIO without the (RA#).
DO NOT attempt to open or dismantle this amplifier.
THIS WILL VOID THE WARRANTY!
100-120V and 220- 240V Switch: This is used to change
the input voltage required to power the amplifier. In the US,
