Introductions
Welcome
Congratulation and thank you for the purchasing M35(t) / M65(t), a multi-function commercial
amplier.These ampliers are designed to provide a big impact in sound reproduction and to
produce the best and highest quality audio at an affordable price. We wish you great enjoyment
and satisfaction when using your amplier, whether you are an installation, or reinforcement
engineer.
Unpacking and Installation
Although it is neither complicated to install nor difcult to operate your amplier, a few minutes of
your time is required to read this manual for a properly wired installation and becoming familiar
with its features and how to use them. Please take a great care may be needed when moving
your set and are required if it ever becomes necessary to return your set for service. Never place
the unit near radiator, in front of heating vents, to direct sun light, in excessive humid or dusty
location to avoid damages and to guaranty a long reliable use.
Connect your unit with the system components according to the description on the following
pages.

M35(t) / M65(t) Setups
Installation
CAUTION : Before you begin, make sure your mixer-amplier is disconnected from the power source, with
the power switch in the “OFF” position and all level controls turned completely down (counterclockwise).
You may stack mixer-ampliers without using a cabinet or you may place a single mixer-amplier
on a surface with 12-inches (about 30cm) of air space around the unit for convection cooling.
Wiring guide
Choose input wire and connectors
We recommends using pre-built or professionally wired balanced line. 22 to 24 gauge cables.
Figure 2.1 shows connector pin assignments for wiring. The RCA input connections can also be
used for unbalanced inputs.
Setups
[ Figure 2.1 Input wire and connectors ]

M35(t) / M65(t)
Choose output wire and connectors
For the amplier output connectors, We recommends using pre-built or professionally wired,
high-quality, and heavy gauge speaker wires. You may use EURO blocks for your output con-
nectors. To prevent the possibility of short-circuits, wrap or otherwise insulate exposed loud-
speaker cable connectors
Using the guidelines below, select the appropriate size wire based on the distance from amplier
to speaker. The wire sizes apply to the 4-ohm tap.
Distance Wire Size
Up to 25 ft. 16 AWG
26~40 ft. 14 AWG
41~60 ft. 12AWG
61~100 ft. 10AWG
101ft~150 ft. 8AWG
151~200 ft. 6AWG
NOTE : Custom wiring should only be performed by qualied personnel. Class 2 wiring is re-
quired.
CAUTION : Never use shielded cable for output power wiring

[ Figure 2.2 How to connect speakers ]
INPUT : Connect microphones or balanced line-level sources to mixer-amplier balanced inputs.
Set Gain volume accordingly. Connect unbalanced line-level signals to RCA input connectors.
OUTPUT : Maintain proper polarity on output connectors.
For each output channel, connect the output EURO block terminals to the loudspeaker loads.
Use terminals marked COM and 4Ω / 8Ω for a loudspeaker load, or use terminals marked 25V,
70V, COM for constant-voltage speaker loads.
Connect the COM terminal to speaker negative(-) lead; connect one of the other terminals to
speaker positive(+) lead.
The impedance and output voltage are same as following Table 2.1
M35(t) 4Ω / 11.8V 8Ω /16.7V 140Ω / 70V 17.8Ω / 25V
M65(t) 4Ω / 16V 8Ω / 22.8V 75Ω / 70V 9.6Ω / 25V
[ Table 2.1 Output voltage and impedance ]
NOTE : Impedances indicated in the table 2.1 represent the total speaker system impedances.
Speaker connection is shown in Figure 2.2
