TOA V-01S – VCA Volume Control Module, 900 Series

Product Overview

The TOA V-01S is a voltage-controlled attenuator (VCA) module for the TOA 900 Series and BG-2000 Series mixer-amplifiers, enabling smooth, remotely controlled audio level adjustment from an external 0–10V DC control source. This plug-in module is the correct solution for installations that require centralized or automated volume control over a TOA distributed audio zone without manual access to the amplifier chassis. AV integrators designing TOA-based systems with building automation integration, preset recall, or remote zone volume control will find the V-01S a compact, cost-effective way to add voltage-controlled gain management to the 900 Series platform. The module draws controller power directly from the amplifier chassis, eliminating the need for a separate power supply for the control interface.

Product Description

The V-01S plugs into an available module slot in a compatible TOA 900 Series or BG-2000 Series mixer-amplifier chassis, adding a VCA-controlled gain stage in the signal path. The gain control range spans -100dB to 0dB, mapped to the 0–10V control voltage input, allowing fine-grained attenuation from full signal to effective mute. The module's terminal block provides both the control voltage input and a 24V output that can power a compatible external controller or wall-mounted potentiometer panel, simplifying wiring in zone control scenarios. For commercial AV installations in conference centers, multi-room facilities, or retail environments where zone audio levels must be managed from a central control system, the V-01S provides direct analog control voltage compatibility with building automation platforms that output 0–10V zone control signals. The compact plug-in form factor keeps the VCA function integrated within the TOA amplifier chassis, reducing rack space and external cabling compared to outboard remote-volume solutions.

Key Features

• VCA Gain Control, -100dB to 0dB — Full-range voltage-controlled attenuation from 0–10V DC control input, enabling remote zone volume adjustment from building automation or dedicated control systems.
• 900 Series and BG-2000 Series Compatible — Plug-in module for TOA 900 Series and BG-2000 Series mixer-amplifier chassis; installs in any available module slot without external adapters.
• Integrated 24V Controller Power Output — Provides 24V DC from the terminal block to power a compatible external controller, eliminating a separate power supply for the control interface.
• Analog Control Voltage Input — Accepts 0–10V DC control signals from building automation systems, touch panel controllers, or wall-mount potentiometers for zone volume management.
• Compact Plug-In Module — Self-contained within the amplifier chassis module slot, reducing rack space and external cabling needed for remote volume control in distributed audio systems.
