The DA-P1 portable DAT recorder is designed for gathering high quality sound on remote locations. It has everything you need to plug in your mic, and start recording. Two high quality mic preamps are loaded on the side of the DA-P1. Phantom Power is available for use with condenser mics. A switchable limiter and -20dB pad are also on-board to help safeguard against clipping. Everything can run from the battery, for up to 100 minutes of recording time with phantom power on, and a full 2 hours with phantom power off. The DA-P1 ships with one BP-D1 rechargeable battery. Additional batteries can be purchased separately, if required. Of course, the DA-P1 is designed for convenient use in the field. The XLR plugs have locking connectors to prevent accidental disconnection. All critical controls are recessed to prevent casual bumps from stopping the recording. All of the connectors, displays and controls are ergonomically located for use if the DA-P1 is hanging at your side from the included shoulder strap, or sitting on a table. For transfers back at the studio, unbalanced RCA analog I/O and SPDIF coax digital I/O ports are provided. (SCMS codes are overridden, allowing hassle-free transfers of your captured material.) The optional CS-D1 carrying case offers additional protection for the DA-P1 for those recordists that are constantly on the road. While batteries can be charged inside the DA-P1, the CB-D1 can also be used to charge batteries externally.
