Building on the QuikWave family of digital sound boards, the DM2204A can play back up to 128 sound files stored in its two EEPROMs. Windows-based .WAV files digitized in 8-bit, mono PCM format at sampling rates of 6, 8, 11, 16 or 22 kHz are supported. Up to 5.5 minutes of sound can be stored when a 6-kHz sampling rate is used.
Playback can be activated by either closing a contact or via logic pulses. Capable of battery operation, the standalone sound board can deliver outputs of up to 1W directly into a speaker. Available without the EPROMs, single-unit price is $48.
