Product details

Sure Electronics AA-AK31141 Audio Record and Playback Kit

This cost-efficient record and playback kit is great for point-of-purchase displays, haunted houses, or any application where an event-driven (use the onboard switches or wire to an external switch) pre-recorded message is needed. An ISD1730 IC is used for high-quality, multi-message voice recording and playback via the built-in audio amplifier. Voice signals can be fed into the IC for recording through two independent paths: a differential microphone input (for use with the included microphone element) or a single-channel 42k ohm analog input.

The ISD1730 provides up to 670 mW (with 5.5 VDC power supply) of Pulse Width Modulation (PWM) Class-D speaker amplification (to power the included 3/4", 8-ohm driver) and a separate analog output for use with an external amplifier (sold separately). Up to four messages (20 seconds of total message duration available) can be recorded and saved into the ICs non-volatile flash memory that maintains recordings, even without power.

A green LED is used as the operating indicator and operating input voltage spans a range from 2.4 to 5.5 VDC to ensure that the kit is optimized for a wide range of battery options; you can even use USB bus power! Kit requires assembly.

Note: Speaker wire in the finished picture is not included.
