900 Series Unbalanced Line Input Module

The TOA Electronics 900 Series Unbalanced Line Input Module accepts unbalanced line-level signals through a female XLR connector. It is designed for professional audio installations that require a dedicated input channel for sources such as CD players, tuners or tape decks.

Upgrade from basic mixer channels

This module replaces a fixed line input on a 900 series frame, adding -20dB sensitivity and adjustable gain from -30 to 0dB. The jump is worth it when you need a noise floor of -106dB and a full 20Hz-20kHz response for critical listening environments.

Check frame compatibility and signal levels

Verify that your 900 series frame has an available module slot and that the source equipment matches the 220 kOhms input impedance. Confirm the unbalanced wiring scheme suits your cabling plan before ordering.

Questions about this item

What size rack slot does the 900 Series module occupy?

The module is built for a single slot in a TOA 900 series frame; no extra brackets or adapters are required.

How is the gain set after the module is seated in the frame?

Insert the module, then adjust the front-panel gain control between -30 and 0 dB; the step often missed is re-checking level after the first signal passes.

When should the XLR connector be inspected or replaced?

Inspect the female XLR-3-31 pins for oxidation or bent contacts whenever noise exceeds the -106 dB floor or after heavy plug cycles.
