CHAPTER 1 INTRODUCTION

In this manual we use "DA to cover both the DA-88
(Version 4.00 and earlier models) and the DA-38. We
state them separately only when needed.

The RC-848 multi-function remote control unit is the
heart of a professional production system of digital and
analog audio and video tapes ; it has Accessory l and 2
connectors to control TASCAM analog machines, and a
standard RS-422 interface to control VTRs or others.

The RC-848 can control a maximum of 6 DAs or
synchronize a system of up to 16 DAs to sample
accuracy.

More specifically the RC-848's capabilities include the
following:

0 Menu names you use most frequently can be stored in
battery backup memory for instant access.

0 Battery backup of the last menu screen displayed
before selecting another machine, allowing you to
directly return to that menu when selecting the
corresponding machine again. This is also true of the
LOCATE TIME display.

0 Park position, this helps to eliminate a lag between a
master and slave.

O Crossfade time for click free punch-in recordings.

0 Instant reset of settings at multiple specific menus
0 Automatic offset entry
0 99-point autolocator functions

0 Jog/Shuttle wheel for locating specific points on audio
or video tapes at variable speeds

0 Split mode for punch-in recording referenced to a
video picture.

SOFTWARE UPDATES

Many capabilities which were not available on earlier
models have been implemented on the RC-848 ROM
version 4.00 and above. Information on all changes and
new features are included in this manual. If you want to
make sure of the version number of your model,
simultaneously press REW, F FWD, and STOP after
switching on power to the RC-848 and before a
momentary illumination of all LEDs stops. The initial
screen will change to read 4.00 or a higher number. To go
back to the initial screen, switch the unit off, then power
on again.
