Setup
Setup
Installation
CAUTION: Before you begin, make sure your mixer-amplifier 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-amplifiers without using acabinet or you may place asingle mixer-amplifier
on asurface with 12-inches (about 30cm) of air space around the unit for convection cooling.
When using an equipment rack, do not mount units directly on top of each other. Allow 2U be-
tween units for convection cooling. The side walls of the rack should be aminimum of 2-inches
(about 5cm) away from the amplifier sides, and the back of the rack should be aminimum of
4-inches (about 10cm) from the mixer-amplifier rear panel.
Installation
1. Locate the two rack ears and six rack-ear screws supplied.
2. Place arack-ear flush with the right front of the chassis.
3. Insert ascrew into the bottom hole of the rack-ear and chassis. Screw it in.
4. Insert ascrew into the mid hole of the rack-ear and chassis. Screw it in
5. Insert ascrew into the top hole of the rack-ear and chassis. Screw it in.
6. Repeat steps 2to 5for the left side of the chassis.
7. Remove the four legs from bottom of unit.
8. Please refer to Figure .

Setups
Wiring Guide
Choose input wire and connectors
TKOKO recommends using pre-built or professionally wired balanced line,22 to 24 gauge cables.
Figure shows connector pin assignments for wiring .The RCA input connections can also be used
for unbalanced inputs.

Setups
Choose input wire and connectors
For the amplifier output connectors,TKOKO recommends using pre-built or professionally wired,
high-quality, and heavy gauge speaker wires.You may use screw terminal for your output connec-
tors.To prevent the possibility of short-circuits, wrap or otherwise insulate exposed loudspeaker
cable connectors.
Using the guidelines below, select the appropriate size wire based on the distance from amplifier
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. 12 AWG
61~100 ft. 10 AWG
101~150 ft. 8 AWG
151~200 ft. 6 AWG
NOTE: Custom wiring shoule only be performed by qualified personnel. Class 2wiring is re-
quired.
CAUTION: Never use shielded cable for output power wiring

Operation
[Expansion M series ]
External equipments connection
By connecting a signal processor such as an equalizer or limiter between the mixer section (PR
E-AMP OUT) and the power amplifier section(AMP IN) of the M series, signals can be tailored
for desired sound output.
NOTE
Inserting a 1/4-inch phone plug into AMP IN terminal disconnects internal power amplifier section
from the mixer section.
[ External equipments connection ]
Sound Processor
Expansion M series
M series mixer-amplifier allows expansion with LINK IN and LINK OUT connector.
If you need more input and output, just this function allows you can do that.
This function affect which signals are heard when another mixer or M series mixer-amplifier are
wired to the mixer-amplifier.

1212
Operation
Preannounce chime
M series mixer-amplifier supply user selectable 2 kinds of preannounce chime.
The way of set up is same as follow figure .
[ Chime selection ]
Priority
This function allows talk over for MIC channel 1 and 2.
All other input signals are muted when this function is activated
during stay "ON" position.
Figure shows the priority switches and its "ON" and "OFF"
Positions.
M series mixer-amplifier supply DC + 15 Volts phantom power to
use condenser microphone with MIC 1 and 2 channels.
Figure shows the phantom power switches and its "ON" and
"OFF" positions.

Operation
Signal input gain control
M series mixer-amplifier can accept variable and wide range input signal with trim pot.
Adjusts the trim pot in a range of 44dB to accept variabe external equipments.
Figure 3.6 shows detail input sensitivities.
[ Acceptable input sensitivity per each channels ]
M series mixer-amplifier has three level priority mute function. When higher level source is acti-
vated,other input signals are muted except same priority level source.
CH3~CH6>CH1~CH2, Chime>Telephone paging.
