The VX-2000 System Manager is an input matrix unit that assigns input signals to 4 audio buses, and functions as the VX-2000 system's main controller. A total of up to 8 units of the VX-200XI, VX-200XR, and 900 Series input modules can be mounted in a System Manager. The VX-2000 can control audio signal routing, priorities, and peripheral equipment, while input and output control settings are performed by way of a PC. Up to 2,000 system events and failures can also be recorded, and the log can be viewed from a PC.

The VX-2000DS Emergency Power Supply Unit supplies the DC power to each equipment in the VX-2000 system by connecting the VX-200PS Power Supply Unit. It keeps the battery unit that contains 2 × 12 V sealed lead batteries charged compensating for the temperature of the battery charging voltage. When the DC power supply from the VX-200PS stops, the VX-2000DS is automatically switched to the backup battery.

The VX-200PS Power Supply Unit is mounted in the VX-2000PF Power Supply Frame when in use. There are 2 DC output channels per unit. Use the VX-200PS in the number suited to the required total system power.

The VX-2000PF permits the VX-200PS Power Supply Unit to be mounted in an equipment rack. Up to 3 VX-200PS units can be installed in the unit.

The VX-2000SF Surveillance Frame is the output matrix section of the VX-2000 system that assigns audio signals to individual zones from 4 audio buses. It can be extended to up to 5 units. A total of 10 units of output modules and control modules can be installed per VX-2000SF. The following 4 types of modules can be used: the VX-200SP Pilot Tone Detection module, the VX-200SZ Impedance Detection module, the VX-200SI Control Input module, and the VX-200SO Control Output module.

A dedicated microphone for the VX-2000 system, the RM-200XF is designed to be exclusively used for emergency broadcast, however it can be used for general-purpose broadcast applications as well.

The RM-200X is a dedicated unit for the VX-2000 system, and permits emergency broadcast as well as general-purpose broadcast.

The WB-RM200 is to mount RM-200X, RM-200M, RM-200SA and RM-210 on the wall.

The S-20S is EV module to be used in conjunction with the 900 series and BG-1000 series amplifier and VX-2000. Up to 4 types of music and messages (6 minutes total time) can be recorded and played back. The USB port facilitates recording by transferring the supplied sound sources from a PC to the unit.

The VP-200VX Power Amplifier Input Module is designed to be used in conjunction with the VP-2064, VP-2122, VP-2241 or VP-2421 power amplifier.

The VP-2064 Power Amplifier features a 60 W-by-4 channels configuration, and uses the VP-200VX Power Amplifier Module per channel.

The VP-2122 Power Amplifier features a 120 W-by-2 channels configuration, and uses the VP-200VX Power Amplifier Module per channel.

The VP-2241 Power Amplifier features a 240 W-by-1 channels configuration, and uses the VP-200VX Power Amplifier Module per channel.

The VP-2421 Power Amplifier features a 420 W-by-1 channels configuration, and uses the VP-200VX Power Amplifier Module per channel.

The VX-200SE Equaliser is a 9-band, 1-channel equaliser to be mounted on the circuit board of the VX-200SP Pilot Tone Detection module or VX-200SZ Impedance Detection module.

TOA's VX-200SI Control Input Module is used to increase the number of control inputs to be used in the VX-2000 system. It features 16 control inputs and is mounted in the VX-2000SF Surveillance Frame. 

TOA's VX-200SO Control Output Module is used to increase the number of control outputs to be used in the VX-2000 system. It features 16 control outputs and is mounted in the VX-2000SF Surveillance Frame. 

The VX-200SP is an audio signal output module of the VX-2000 system with speaker line pilot tone detection. This module is to be mounted in the VX-2000SF Surveillance Frame and detects speaker line short circuits, open circuits by monitoring for the presence of a pilot signal, and ground fault.

The VX-200SP-2 is an audio signal output module of the VX-2000 system with speaker line pilot tone detection. This module is to be mounted in the VX-2000SF Surveillance Frame and detects speaker line short circuits, open circuits by monitoring the terminated resistance value of the end of line unit, and ground fault. Connecting the supplied end of line unit to the end of the speaker line eliminates the necessity of using the speaker line for line monitoring. However, the shielded cable must be used for speaker line.

The VX-200SZ is an audio signal output module of the VX-2000 system with speaker line impedance detection. This module is to be mounted in the VX-2000SF Surveillance Frame and detects speaker line short circuits, open circuits by comparing impedance readings, and ground fault.

The VX-200SZ-2 is an audio signal output module of the VX-2000 system with speaker line impedance detection. This module is to be mounted in the VX-2000SF Surveillance Frame and detects speaker line short circuits, open circuits by comparing impedance readings, and ground fault. Since the module is equipped with 2 speaker outputs (A and B), broadcasts can be maintained even if one of the two outputs fails. Failures are indicated by the LED on the panel.

The VX-200XI module is designed to be used in conjunction with the VX-2000 System Manager, and comes with control input terminals, low-cut and high-cut filters, and gain controls. 

The VX-200XR module is designed to be used with the RM-200X Remote Microphone or RM-200XF Fireman's Microphone. Insert one of these modules into the VX-2000's input module slot for each remote or fire microphone used in the system.
