6.7. MUSIC-ON HOLD (CD AND TUNER ONLY WITH OUTPUT LEVEL)
These terminals are for connecting to the telephone system.
NOTE: When the tuner or CD is turned on, its output signal is always
supplied to these terminals and is not concerned with master
volume. Also, you can adjust to output
level by the volume of internal unit.
8. AUX INPUT CONNECTOR
The sound source (from CD palyer etc.)is connected to this input.
9. PRE OUTPUT CONNECTOR
The pre out signal of this unit can be used for connecting to another
amplifier, e.g. Recorder or signal processor etc.
10. CH1~CH3 MIC INPUT XLR JACK
These are MIC input connectors which are designed electrical
balanced circuitry.
11. TUNER BACKUP SWITCH
Be sure to press this switch before installation.
This is for memory backup of the broadcasting frequency.
12. MIC1, TEL INPUT PRIORITY SWITCH
MIC1 signal is similar priority function with telephone audio signal.
13. 6CDC LINK CONNECTOR
This connector for connecting the optionable external 6CD changer
(ECC-2612) when you purchase seperately.
14. LOW INPEDANCE
These terminals are for connection to low impedance (4Ω, 8 Ω) speakers.
15. HIGH INPEDANCE (SPEAKER SELECTOR OUTPUT TERMINALS)
These terminals are for connection of speaker lines to deliver power
output to speaker. Impedance (voltages) of 70V and 100V are
provided for convenience. In any case, use the speakers whose
combined is equal to or higher than the rated output impedance
of amplifier.

Application Of The Antenna
9
SINGLE CONDUCTOR LEAD WIRE ANTENNA
Connecting the single conductor lead wire antenna of the terminal
of 75 ohms(Picture).
Listening to the broadcasting, fix it after desiding the location and
the direction so that the receipt condition may be optimum.
FM RECEIVING ANTENNA
The electric wave of FM broadcasting is weakening in hills and valleys,
around buildings and in iron-reinforced buildings.
INSTALLATION OF ANTENNA EXCLUSIVELY FOR FM
Listening to the broadcasting, fix the antenna after deciding the location
and the direction so that the reception may be optimized.
INSTALLATION OF ANTENNA USING THE COAXIAL CABLE
Noisy reception may occur in built-up areas and factory sites as around
power cables. This may be the case even when an antenna is used
exclusively for FM. In these regions, install the antenna using 75 ohm
coaxial cable.
INDOOR ANTENNA
In the regions where FM broadcasting is heard comparatively well due
to the near distance to the station or wooden structure, you can receive
broadcasting of good quality by using T-type antenna. (Using matching
trans:300/75 ohms)
AM OUTDOOR ANTENNA
Install the vinyl-coated cable to an outdoor place if the AM reception is
not good enough.

Installation of The Speaker
10
Before you connect the speaker, remove the power cord from the power
outlet and switch the ETR-2112 power switch off. When connecting the
speaker wires to the SPEAKER OUTPUT terminals, use the output
terminals that are suitable for the speaker (see above figure 1-4).
Extreme care must be exercised when connecting to these terminals as
potentially hazardous voltages may be present.
NOTE : Do not exceed the power rating of the amplifier by connecting
more speakers than the unit is rated for. If you are in doubt,
please consult a professional installer.
