Audio-Technica CH9300-FL Voice Module 5-Pack

This pack contains five identical voice playback modules built for public-address and DIY projects. Each board stores MP3 files in 16M memory and operates from a DC 3.6 to 5.2 V supply. They suit shopping malls, schools, gymnasiums and office buildings that need scheduled or triggered announcements.

16M memory with 10 IO trigger channels

The decisive spec is the 16 Mbyte onboard memory combined with ten IO ports that accept one-to-one button or serial commands. Files must be named with five digits from 00001 to 00010 and copied via the Type-C USB link. No other storage capacity or trigger count is available on this model.

Type-C file load and screw-terminal wiring

Installation consists of connecting power within the 3.6 to 5.2 V range, wiring triggers to the ten IO terminals, and dragging MP3 files over USB. The main pitfalls are supplying voltage outside the stated window, using non-MP3 audio formats, or naming files outside the 00001 to 00010 pattern, which prevents playback.

Questions about this item

What does the 16M memory actually hold in a real installation?

The 16Mbyte memory stores MP3 files copied via the TYPE-C connection; file names must be five digits from 00001 to 00010 and the module supports combination playback of up to 1023 audio segments.

How does the USB TYPE-C link limit transfer speed or file format?

The TYPE-C port is used only for downloading MP3 audio files to the onboard memory; the module decodes all standard MP3 bit-rates and sampling rates from 8 kHz to 48 kHz without additional software.

What physical space and power does each board need to mount in a rack or enclosure?

Each board measures 14.33 in wide, 12.83 in high and 9.06 in deep, weighs 0.032 kg and operates from a DC supply between 3.6 V and 5.2 V.
