Product Overview

The TOA U-01P is an unbalanced line input module with a 1/4-inch phone-jack connector for the 900 Series and other compatible TOA equipment. This line input module lets AV integrators connect sources that use 1/4-inch outputs to a modular mixer-amplifier. The plug-in format adds a gain-adjustable input without changing the host unit. It is a practical input for media players, mixers, and instrument-level program sources in commercial systems.

Product Description

Sources with 1/4-inch outputs are common in commercial audio, and the U-01P provides a matching input for TOA’s modular amplifiers. It installs in a single 900 Series input slot and presents one unbalanced 6.3 mm phone jack for the source cable. A 220 kilohm input impedance suits line-level sources placed near the host unit, with TOA recommending unbalanced runs under about 15 feet. The onboard gain control trims level across a -30 to 0 dB range to match the source. The module runs on 24 V DC supplied by the main frame, so no separate supply is needed. A 20 Hz to 20 kHz response with low distortion keeps program audio clean. Its compact, lightweight format makes it easy to add during installation or a later expansion.
