3. GENERAL DESCRIPTION
TOA's 9000M2 Series Amplifiers are designed to be used in conjunction with optional modules and can be
configured for up to 8 inputs and 8 outputs. Usable modules include the following 9000 series plug-in
modules: D-001T and D-001R (2-channel input), T-001T (Audio output expansion), C-001T (Control I/O
expansion), ZP-001T (Zone paging), AN-001T (Ambient noise sensor), and RC-001T (Remote controller
interface), as well as 900 series input modules. The most appropriate modules can be selected depending on
applications.
The 9000M2 Series Amplifier can be used as a mixer that is appropriate for speech or sound reinforcement
applications. It is equipped with signal processing and control functions, permitting all parameters to be set at
the amplifier.
Each input can also be set as a paging input, to which one of 3 priority levels can be assigned.
The paging input takes precedence over other mixing inputs, thus allowing priority paging calls to go through
to the designated outputs. Paging calls can be activated by triggers of various types. Multiple paging calls can
be selectively used according to their priority levels. Thus, the 9000M2 Series Amplifier can effectively meet a
room combining application.
Setting data of both mixing and paging functions can be stored inside the amplifier.
The M-9000M2 is a Pre-Amplifier featuring the above functions.
Besides the M-9000M2's function, the following 9000M2 Series Amplifiers come with power amplifiers, out of
which A-9060DHM2 and A-9120DHM2 can perform 2-channel or stereo broadcast in stand-alone operation.
A-9060DHM2: 60 W (70 V output) x 2
A-9120DHM2: 120 W (70 V output) x 2
A-9060SM2: 60 W x 1
A-9120SM2: 120 W x 1
A-9240SHM2: 240 W (70 V output) x 1
All settings that can be made at the unit can also be made on the PC using the supplied dedicated software.
[Compatibility of the firmware version and software version]
This instruction manual supports the 9000M2 Series amplifiers' firmware Ver. 2.00 or later and the PC Setting
software Ver. 2.00 or later.
Some of the functions described in this manual do not work on the firmware and PC software versions earlier
than Ver. 2.00. If you use the older version of the 9000M2, update the firmware and PC software versions to
the latest ones. Also, be sure to back up the 9000M2's setting data using the PC Setting software before
performing updates.
Notes
• While performing version update, make sure to prevent the power cable and communication cable from
accidentally coming off.
• Once updated to firmware Ver. 2.00 or later, you cannot downgrade back to firmware Ver. 2.00 or earlier.
The indication "INVALID VERSION" is displayed on the 9000M2 amplifier's front-mounted display (VFD) and
PC's screen when attempting to perform downgrade. (Refer to the screen shot below.)
The indication is displayed for a few seconds, then the 9000M2 amplifier restarts with the version remaining
unchanged.
