Product description
High quality solid-state audio recorder, the ARES-M is principally designed to be used in any ultraportable recording situation, and can replace MINIDISK©. Its recording media is a 1 GB built-in memory,
for the recording of PCM Mono or Stereo audio. MPEG compression allows for longer recording times.
Two “AA” batteries power the unit, offering 10 hours operation.
Equipped with a built-in microphone, it is also delivered with an external clip-on stereo microphone. In
addition extra high quality external Mono (omni-directional) and Stereo (Cardioid) clip on microphones are
available as additional accessories. A traditional external microphone can also be used thanks to the XLR
input cable supplied with the unit.
Designed for radio applications, the ARES-M offers instant start-up, one button recording, automatic level
control, internal loudspeaker, voice operated recording, low-cut filter and on-board graphic audio editor.
Compatibility
The ARES-M offers a miniature USB port. Through this connection, the internal memory appears on the
“desktop” as a mass storage device (external drive) of the PC / MAC and requires NO additional software
or drivers.
