Figure shows the FS-7012PA.
9. YA-7000 Receptacle
Mount an optional YA-7000 module from this
receptacle. (See page 11.)
Note
Use of the YA-7000 permits the main amplifier to
be switched over to a standby amplifier if the
main amplifier fails.
10. Power Cord
Connect this cord to the wall AC outlet (230 V
AC, 50 Hz).
11. Speaker Output Terminal (with cover)
High-impedance, 100 V line output for speaker
connections.
Note
Connect this terminal to the YA-7000 when the
YA-7000 has been mounted.
• FS-7006PA
M4 screw terminal; barrier distance: 9 mm; load
impedance: 16.7 Ω
• FS-7012PA
M4 screw terminal; barrier distance: 9 mm; load
impedance: 8.3 Ω
Note
Never connect this terminal to the speaker output
terminal of other FS-7006PA or FS-7012PA
power amplifier. Failure to follow this instruction
could lead to equipment failures.
12. Functional Earth Terminal
Connect this terminal to the functional earth
terminal of external equipment if excessive noise
is generated when the power amplifier is
connected to the external equipment. This could
reduce noise.
Note: This terminal is not for protective earth.
13. Volume Control Bypass Control Input Terminal
Bypasses Volume Control (3) on the front panel
and allows announcements to be made at
maximum volume.
(Open voltage: under 24 V DC; short-circuit
current: under 10 mA; 2P terminal block)
14. Audio Signal Input Terminal
0 dB, 10 kΩ, balanced, 3P terminal block
