Chapter 1 General Information

This chapter presents the main features and capabilities of the MMR-8 hardware and a functional

overview of its Panel/Display states. MMR-8 product specifications are also included.

MMR-8 Introduction

MMR-8 Front View

The MMR-8 is a non-linear digital replacement for the analog or digital tape machines found in recording

studios and broadcast facilities, and for magnetic film dubbers found in film and video post-production

facilities. The MMR-8 can play back and record eight tracks of material from one or more SCSI hard

drives or other removable media. Playback can be in exact or track-slipped synchronization to industry-

standard film, video, and audio devices, whether they are mechanical tape-based or hard drive-based.

Audio files recorded on the MMR-8 consist of selectable linear 16-bit or linear 24-bit words at sample

rates of 48.0 kHz or 44.1 kHz, modifiable to a pull-up or pull-down rate, including conversion between

PAL, film, and video, making fourteen total discrete sampling rates. The analog I/O section uses

balanced +4 dBu analog connections on DB-25 connectors that are pin-compatible with the TASCAM

DA-88 and may use the same cables. The DIO (Digital I/O) connection provides digital audio inputs and

outputs which conform to the AES/EBU standard for direct digital recording and playback. The digital

I/O connector can use a standard DA-88 cable (the analog cable – not TDIF) to provide four stereo AES

inputs and four stereo AES outputs. See the Pin out drawing given in Appendix D for detailed

information. Any digital input can be selected as the sample clock reference source. Additionally, any one

of the four digital input signal pairs can be selected for routing through a sample rate converter.
