The SX-2000AO is an audio output of the matrix system and can be mounted in an EIA equipment rack (2 U size). Multiple units can be decentralized in a whole system. It is equipped with eight audio outputs, and two inputs can be mixed and output. It is also equipped with eight control inputs, and eight control outputs. The SX-2000AO receives audio signals from the audio input unit via digital transmission, but an analog audio input function (1 channel) enables simultaneous all-zone calls for use in emergency situations. Audio output levels are indicated on the level meters provided for each output channel. Volumes can be adjusted for each channel using the volume controls on the front panel or the SX-2000 software. The volume controls can be locked. Any output channel can be monitored using the internal speaker. Two channels of local audio inputs with control inputs are provided as the dedicated audio inputs. Its functions include an amplifier switching function that automatically switches the power amplifier to the standby amplifier if the power amplifier fails, and a surveillance function that self-diagnoses the speaker lines. Equipped with two channels of interfaces for connecting to the Emergency Power Supply units, making it possible to configure the system to operate during a power failure. One control IN/OUT interface allows the number of control inputs and outputs to be increased. The SX-2100AO has two power inputs and can support a dual-redundant power supply system.

The SX-2100AI is an audio input of the matrix system and can be mounted in an EIA equipment rack (2U size). Multiple units can be decentralized in a whole system. It features modular construction that allows it to handle from two to eight inputs per unit. Audio signals are transmitted digitally to the audio output unit, but an analog audio output function (1 channel) enables simultaneous all-zone calls for use in emergency situations. Audio input levels are indicated on the level meters provided for each input channel. Volumes can be adjusted for each channel using the volume controls on the front panel or the SX-2000 software. The volume controls can be locked. Any input channel can be monitored using the internal speaker. It is also equipped with 16 control inputs, and 16 control outputs. It is equipped with two power inputs, allowing for a redundant power system.

SX-2000SM can be used in combination with an optional audio input unit, audio output unit, and remote microphone of the SX-2000 Series to make up a complete matrix system and can perform audio signal routing and priority control for the entire system. The SX-2000SM itself is equipped with 8 control inputs, 8 control outputs, failure status outputs, failure data inputs/switches, access indicators mode indicators and failure indicators enabling a wide rage of controls and status monitoring. Each control can be performed by way of a CF card inserted into the SX-2000SM unit. Operations of the entire system can be recorded and their contents stored on a CF card as an operation log.
The SX-2000SM also features two power inputs making possible the creation of a dualredundant power system.
