Sony 3348

48-channel DASH digital audio recorder. Uses 1/2" tape and provides up to one hour of recording time on 14" reels. DASH (Digtial Audio Stationary Head) format recording has evolved to become the worldwide de-facto standard for large scale multitrack audio recording.

DASH Compadibility:
Compatible with PCM-3324, PCM-3324A, PCM-3324S DASH recorders, allowing recording and playback of existing digital audio tracks 1-24 and the ability to add tracks 25-48.

High Sound Quality:
2X oversampling A/D and D/A with digital filters..

Flexible Digital I/O:
Assignable 2 channel digital I/O (AES/EBU, and SDIF-2 unbalanced) and 48-channel SDIF-2 balanced digital I/O

Advanced Features:
Real-time digital "Ping-Pong" function. Fs shift function shifts down the sampling frequency by 0.1% for film/video operation.

Sound Memory Function:
20 sec stereo/40 sec mono Sound Memory with Start/End point editing. Four trigger modes: Manual, Timecode, Audio and Parallel switch.

High Speed Transport:
Heavy duty transport offers unprecedented speed and stability.

Built-in time code generator/reader capable of handling SMPTE drop frame/non-drop frame, EBU and film time codes 48kHz, 44.1kHz or 44.056kHz sampling frequency selectable

Advanced digital/analog output function enables pre-delay adjustment in 1-sample steps to compensate for signal processing delay in external equipment

Approx 20 seconds of digital audio data can be stored in sound memory and re-recorded back onto tape at any position
