• A-9060DH, A-9120DH

This figure represents the A-9120DH.

33. Speaker output terminal

Connects the 70 V high-impedance speaker.

34. AC inlet

Connects to the supplied power cord.

35. RS-232C serial communication port

Connector for communications with a personal
computer or control equipment.

36. Functional earth terminal

Hum noise may be generated when external
equipment is connected to the unit. Connecting
this terminal to the functional earth terminal of the
external equipment may reduce the hum noise.

Note: This terminal is not for protective earth.

37. Mode switch

Selects the unit's operation mode (either matrix
or mixer).

Note: Only the matrix mode is currently available.

38. Control-I/O connection terminal

Connect a 10 k

Ω (linear taper) variable resistor to

the remote volume control terminals (REMT VOL
1 and 2) or input the DC voltage of 0 to +10 V
when remotely adjusting the volume.

Input and output terminals (IN and OUT) are
used to change the unit's internal status or output
internal status data to external equipment after
having received various control signals.

39. Blank panel (accessory)

Attach the blank panels to open slots.

40. Module slots

900 Series or 9000 Series modules can be
inserted into these slots.
(Refer to

p. 50 "MODULE INSTALLATION"

)

41. Preamplifier output

and Power amplifier input terminals

[M-9000 Matrix mixer]
There are 2 preamplifier output terminals.
0 dB,

6

00

Ω, balanced type

[A-9060DH and A-9120DH Amplifiers]
There are 2 preamplifier output terminals and 2
power amplifier input terminals.
Connecting a plug to the power amplifier input
terminal internally disconnects the preamplifier
section from the power amplifier section.
Both terminals: 0 dB, 300

Ω, unbalanced type
