Designed for installed sound environments, it gives system integrators a modular path to expand analog input capacity without external preamplifiers or additional signal processing hardware. Its electronically-balanced inputs accept both microphone and line-level sources, making it suitable for boardrooms, houses of worship, conference centers, and any installed AV system built around the D-901 platform.\u003c\/p\u003e\u003cp\u003eThe module's 24-bit A\/D converter with 48 kHz sampling preserves audio fidelity across the full 20 Hz to 20 kHz range at plus or minus 1 dB, while a dynamic range exceeding 100 dB and total harmonic distortion below 0.05 percent meet the demands of professional installed audio. Phantom power availability and input sensitivity are managed from the host main frame, keeping the module itself compact and installation-ready. The removable terminal block connectors simplify field wiring and replacement without soldering.\u003c\/p\u003e\u003cp\u003eFor integrators working within TOA's modular ecosystem, the D-921E provides a straightforward, reliable expansion option. Its pre-coated steel plate panel and compact form factor allow clean rack integration alongside other D-901 series modules, maintaining system consistency across large or multi-zone installations.\u003c\/p\u003e","brand":"TOA ELECTRONICS, INC","offers":[{"title":"Default Title","offer_id":52446260723896,"sku":"47240","price":341.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0871\/7382\/4696\/files\/47240_TOA-D-921E-Digital-Mixer-Two-Channel-Mic_Line-Input-Module_ALT01sqr.jpg?v=1789136142","url":"https:\/\/soundpro.com\/products\/toa-d-921e","provider":"SoundPro","version":"1.0","type":"link"}
