Product OverviewThe TOA U-01R is an unbalanced line input module with an RCA pin-jack connector for the 900 Series and other compatible TOA equipment. This RCA line input module lets AV integrators connect consumer-style sources such as media players, tuners, and mixers to a modular mixer-amplifier. The plug-in format adds a gain-adjustable input without replacing the host unit. It is a practical choice for background music and program audio sources that use RCA outputs.Product DescriptionMany program sources in commercial audio still terminate in RCA connectors, and the U-01R provides a matching input for TOA's modular platform. It installs in a single 900 Series input slot and presents one unbalanced RCA pin jack for the source cable. A 220 kilohm input impedance suits line-level sources placed near the host unit, and TOA recommends source runs under about 15 feet for unbalanced connections. The onboard gain control trims level across a -30 to 0 dB range to match the source output. The module draws 24 V DC from the host main frame, so no external supply is needed. A 20 Hz to 20 kHz response with low distortion keeps background music and announcements clean. Its compact size and light weight make it easy to add during commissioning or a later expansion.Key Features RCA Pin Jack — Accepts consumer-style line-level sources on a single unbalanced RCA connector. Adjustable Gain — Onboard control trims input level across a -30 to 0 dB range. High Input Impedance — A 220 kilohm unbalanced input matches common program sources. Host-Powered — Runs on 24 V DC from the 900 Series main frame with no external supply. Full-Range Response — A 20 Hz to 20 kHz bandwidth with low distortion preserves audio quality. Modular Format — Fits one 900 Series input slot to expand a mixer-amplifier.
