TA-60 / TA-120
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 a cabinet or you may place a single mixer-amplifier
on a surface 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 a minimum of 2-inches
(about 5cm) away from the amplifier sides, and the back of the rack should be a minimum of
4-inches (about 10cm) from the mixer-amplifier rear panel.
How to attach rack ears
1. Locate the two rack ears and six rack-ear screws supplied.
2. Place a rack-ear flush with the right front of the chassis.
3. Insert a screw into the bottom hole of the rack-ear and chassis. Screw it in.
4. Insert a screw into the rnid hole of the rack-ear and chassis. Screw it in
5. Insert a screw into the top hole of the rack-ear and chassis. Screw it in.
6. Repeat steps 2 to 5 for the left side of the chassis.
7. Remove the four legs from bottom of unit.

For the amplifier output connectors,HPA recommends using pre-built or professionally wired,
high-quality, and heavy gauge speaker wires.You may use EURO blocks 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 2 wiring is re-
quired.
CAUTION: Never use shielded cable for output power wiring

INPUT: Connect microphones or balanced line-level sources to mixer-amplifier 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 Ioads.
Use terminals marked (GND) and for a 4-ohm loudspeaker load, or use terminals marked
to and COM for constand-voltage loudspeaker 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.
TA-60 4Ω/ 15.5V 10Ω/ 25V 83Ω/ 70V 165Ω/ 100V
TA-120 4Ω/ 22V 5.2Ω/ 25V 42Ω/ 70V 83Ω/ 100V

TA-60 / TA-120 Operations
Operations
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 TA 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.
Expansion TA series
TA 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 TA series mixer-amplifier are
wired to the mixer-amplifier.

TA-60 / TA-120 Operations
TA series mixer-amplifier supply user selectable 4 kinds of preannounce chime.
The way of set up is same as follow figure .
Preannounce chime
Figure shows default set in factory. You can move the position of jumper on the T3 of main PCB
for changing pre-announce chime.
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” posi-
tions.
Phantom power
TA 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.

Music On Hold
Connect mixer-amplifier MUSIC ON HOLD connector to music-on-hold input on telephone inter-
face/PBX like telephone pager. Set MUSIC ON HOLD volume to proper level.
TA series mixer-amplifier supply two way of MUSIC ON HOLD function.
When MUSIC ON HOLD slide switch is “INT” position, MUSIC ON HOLD output is routed from
option CDP or MP3 module internally.
When the slide switch is “EXT” position, MUSIC ON HOLD output is routed from LINE IN chan-
nel ( only channel 6 ) connected external music source.
Signal input gain control
TA 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.
Priority Control
TA series mixer-amplifier has three layer priority mute function. When higher level source is acti-
vated, other input signals are muted except same priority level source.
CH3~CH6>CH1~CH2, Remote MIC, Chime>Telephone paging.
