Manufactured from 2004 to 2005


Universal Digital Recorder

The ARES-BB was designed as a compact, high quality, solid-state easy-to-use portable digital audio recorder. Its recording media is PCMCIA of Compact Flash cards (Capacity unlimited), for the recording of PCM Mono or Stereo audio. Optional MPEG compression allows for longer recording times.



Key features

The unit can be powered by 6 “AA” (LR6) batteries, rechargeable “AA” cells or an optional lithium-ion battery pack, offering in excess of 15 hours operation. Especially suited to table-top applications thanks to it’s tilting keyboard. It can also be shoulder-hung in a carrying case for on-the-move recordings. The ARES-BB can operate with any standard dynamic microphone, and +48V powering is also provided allowing the use of any commercially available condenser microphones.

The ARES-BB offers instant start-up, one button recording, “takes” directory, large back-lit display, powerful vortex filter, automatic level control and internal loudspeaker. Optional internal software authorizations allow the machine to record MPEG compressed audio, to emulate a Digigram PCX sound card via USB and do internal audio editing in the field.

A large choice of accessories are available, such as power supply, carrying cases, cables etc to meet specific requirements.

Solid State recording: Menu driven
PCMCIA Compact Flash cards: Long battery life
USB port: Lightweight Ultra portable
Phantom powering: MS decoder
Optional internal audio editor: FAT 16/32 operation
Optional MPEG Compression: Reliable


The ARES-BB offers a USB port. Through this connection, the internal PCMCIA card appears on the “desktop” as n external drive of the PC / MAC. Naturally the card can be removed from the machine and directly inserted into the workstation if required. The FAT 16/32 file system has many advantages over the previous LFS system, meaning that individual takes can be removed at any time and MARKERS can be added to recordings during both record and playback.


The ARES-BB works with ATA PCMCIA cards, Strata Flash cards, compact flash cards and Microdrives (The last two require card adapters).
