19. AUTO INPUT switch
When this switch and INSERT are both previously
activated, the channel inputs selected by REC FUNCTION are automatically switched to directly feed the outputs whenever the transport goes into rewind, fast-forward, shuttle, or stop mode. This allows the talent in studio to talk to the engineer in control room without having to change any settings on the mixer.
20. INSERT switch
Lets yen monitor tape during preroll and postroll for punch-
in recording. See table below.
Relationships between the output signals, transport modes and switch settings
21. RHSL switch
Puts the deck into rehearsal mode which allows you to check the auto punch in and out points for accuracy.
22. AUTO IN/OUT switch Automates the punch-in sequence (preroll, punch in, punch out, and postroll) as you have set during rehearsal.
23. CLEAR key Defeats the RHSL and AUTO IN/OUT functions.
24. REPEAT I-2 switch
Lets the tape play between two MEMO points.
25. LOC I and LOC 2 keys
LOC 1 locates the tape to the MEMO I point, and LOC 2
to the MEMO 2 point.
26. REW key
Winds the tape at high speed in xve~se.
0 When you press F.FWD or REW for the first time after
powering up ok replacing the tape, this will mn at an intermediate speed for a few seconds before starting running at the expected high speed. During this interval the transport is detecting the tape characteristics.
26. STOP key Disables the current transport mode and stops any tape motion.
29. PLAY key Enables play mode ; or, punches out of record if pressed during record.
30. RECORD key Pressing PLAY while holding RECORD initiates record on
any track whose REC FUNCTION indicator was blinking
to show Record Ready mode.
Hitting RECORD during play lets any “Ready” track punch
into record.
31. SHUTTLE switch and the knob Pressing the switch to let its LED turn on allows you to use the knob to monitor the tape at variable speeds in
search of a specific point. Turning the knob to the right of center rolls the tape in the forward direction, and turning it to the left of center provides reverse cueing. The further you turn it in either way, the higher the tape speed will be. The initial speed is 1/4 times normal play speed, and if you turn the knob all the way to the left or right, the tape will play at 8 times normal play speed.
Pressing the SHUTTLE switch during recording gets you out of record, allowing you to begin to “shuttle” the tape
immediately.
SHUTTLE will automatically be disabled if you leave the knob at its ce.nter position for IO seconds.
32. Peak level meters Register the signal levels being fed to the outputs, the levels coming either from the inputs or the tape, as shown
in the left column of this page.
Pressing REW during recording punches out and the tape rewinds.
27. F.FWD key
Winds the tape at high speed in the forward direction.
Pressing F.FWD during recording punches out and the tape fast forwards.
i0
33. REC FUNCTION switches Put the corresponding tracks into Record Ready mode, or
directly into Record if RECORD and PLAY axe previously pressed.
The associated LEDs flash to indicate Record Ready, and turn on solid during Record.
Page 7
34. CHASE key
Lets the slave DA-88(s) chase and lock to the same ABS time point as the master. Once locked op. they will play, record, or fast-wind in sync in response to the commands from the master.
The installation of the optional SY-88 sync board allows the DA-88 to run in sync with VTRs or other ATRs (digital or analog). For more details, refer to the SY-88
manual.
35. CLOCK switch
Selects the clock to which the deck will be referenced. If the DA-88 is used as a stand-alone deck, it has to be referenced to the iNT(ernal) clock.
The WORD clock is used when making a digital copy between the DA-88 and other digital tape machines, or when letting them run in sync (the optional SY-88 Sync Board is required).
For the DA-88 to be slaved to VTRs, select VIDEO (the optional SY-88 sync board is required).
When o”e or more DA-88s are hooked “pas the slaves, the CLOCK switch on them are locked out (all the associated LEDs turned off), and they are automatically referenced to the clock to which the master DA-88 is referenced.
The next two items can operate only when the optional SY­88 sync board is installed. For their functions, refer to the SY-88 manual.

Formattinq a Tape
.SY-88 Sync Board
Before starting to record any audio program on a new tape, it should be formatted, i.e. it should be time-indexed and given tracking and other subcode data.
NOTES
o Be sure to let formafling start from the very beginning of the tape. o Once formatting starts, all transporl control buttons’except STOP are
locked out. If you stop the tape before formatting is complete, reformat it
from the beginning.
o Tapes once used for recording video cannot correctly be formatted. Don’t
try to format such tapes.
To format a new tape :
1. Switch on power to the DA-XX.
2. Load a Hi8 tape into the DA-88.
3. Press FORMAT. Its LED will start blinking.
4. Press FORMAT again. Its LED will turn on solid showing that the deck is ready for formatting.
5. Press the Fs switch to select either of the two sampling rates available. Select
44.1 kHz if the recording will be used as a digital master for CD production. Or, select the professional standard 48 kHz rate for other applications.
13
Page 10

Audio Recording

G’ Once formatting starts, you cannot change the sampling rate. If you notice
that L wrong rate was selected after formatting starts, stop and rewind the tape to the beginning and selecf the correct rate before i-e-starting
formatting.
6. Hold RECORD and press PLAY to let formatting start.
When the tape reaches the end and formatting is complete, it will automatically rewind, stopping at the beginning.
03 Pressing my REC FUNCTION witch after once formatting starts lets audio
be recorded on the corresponding track, But to insure against noise and discontimities of absolute time data, we recommend that you format all tapes all the way to the end before using them for audio record.
m If you attempt to record additional material to augmeizt the original and wish
to format the tape from that intermediate point, be sure to mjjiciently inow back the tape beforehand to prevent an unformatted section being leji in between.
NOTE
When the tape runs from the previously formatted part into the newly formatted part, there could be discontinuities of ABS time data. The tcansition could cause erratic sync if it happens when syncing. If audio data is present over the transition zone, noise could be heard. The best is format a tape from start to end without interruption.

You can set up a maximum of 16 DA-88s for I28 tracks to let them behave in
sync with sample accuracy, one DA-88 serving as the rimster, and all others as slaves, this without having to use any external synchronizer, but simply by connecting their SYNC IN and OUT jacks in series.
0 To synchronize multiple DA-W+ it is imperative that tapes in use are
previously formatted and have ABS time data.
0 You cannot synchroriize tapes if they have been formatted for different
sampling rates.
0 When multiple DA-88s we hooked up, be sure to keep all of them turned on,
whether they are all actually in use or not. If some DA-88s are in record or
play and you turn any others on or off, the recording or playing tapes can run irregularly.

3. Locate the MACHINE ID rotary switch on the rear panel of the master DA-S% and set it to “0”. Similarly, assign “I” to the tirst slave machine, “y to the second slave, and so on, in their order of SYNC IN/OUT connections.
m Operating the MACHINE ID switch when the machine is turned on has no
&ct at all.
To let slaves chase and lock to the master :
4. Turn on the DA-88s (and other equipment as well a.s required).
5. F’ress CHASE on each of the slave machines. They will all be located to the
satne. time point as the master.
6. F’ress a transport control button whatever on the master machine. The slave transports will go into the same mode as the master.
You can enter an offset so slave DA-88s lead or lag the master, each by a different number of hours, minutes, seconds, and frames.
Press DISPLAY 0x1 your slave DA-88 until “OOOOOOOV shows and the OFFSET indicator lights, then you can use its A and 7 keys to enter the desired offset time in I frame steps, up to +/-1 hour, 00 minute, 00 second, 00 frame.
To speed up the number entry, you can hold down either A or V and press
DISPLAY. Each time you press DISPLAY, the next upper (left) two digits will
fast increment.
To disable any offset you’ve entered, hold 1 or V and press the other.

0 Digital dubbing
With digital recording, how many times dubbing is repeated, no hiss or dismrtion is added ; you can copy important muldtiack tapes as many times as you need to creatz work tapes or copies for d&rib&x without having to worry about any
deterioradon.
DIGITAL l/O
PW%3D
DIGITAL l/O
To make a digital copy between DA-88s :
I. Making sure that every equipment of you system is turned off, connect the.
source machine’s DIGITAL WO porl to the target machine’s DIGITAL I/O port by means of the PW-88D cable.
2. After having made the necessary connecdons, nnn on the whole system.
3. Put the master (source) machine into the Dighal output mode as described on page 15.
4. Load the master m&itrack tape on the source machine, and an already formaxed blank tape on the target machine.
5. Check to see that all the REC FUNCTION switches on the source machine are turned OFF.
6. Check to see that all the REC FUNCTION switches on the target machine are turned ON.
7. Press CHASE on the target machine, so its tape will be located to the sane time point as the source machine,
8. Hold RECORD and press PLAY on the source machine to let the master mul&rack tape start playing. The target machine will automatically go into record mode, and the master tape will be copied on the taxget tape.
Use the IF-88AE interface unit if you want to make a digital copy between the
DA-88 and other digital machines with AES/EBU Digital I/O or SPDIF port. Or
use the.IF-88SD in&face unit for transferring da@ bewan the DA-88 and other digital machines with SDIF-2 port. Both units are optionally available. Once you
have connected them, you can copy digital audio from one to the other machine by
following the same prowduE a.s for normal digital audio recording.
Whichever output mode you select (Digital or Analog), audio data is available at both the digital and analog outputs at one time. But remember the following :

Page 22
In the Analog output mode, the analog outputs are timed to compensate for the DIA conversion time as well as the anticipatory A/D conversion time (42 samples in total as shown). But this in turn disturbs the digital output timing. On the other hand, in the Digital output mode, the analog outputs will lag because this mode disables the compensation circuit so that the digital outputs are timed as it should.

Error Messages

No clock is coming in. Or, the CLOCK switch is not set to
match an incoming clock. Check also if the slave machines (ID-numbered 1.15) are correctly connected in series through their SYNC IN/OUT connectors, and if the master is ID­numbered 0.
E. k. c u t : The tape has broken. The only remedy is replacement of the tape.
E.d <a:
The DIGITAL l/O port is accidentally unplugged.
E.dg:
Condensation occurred on the head drum. Leave the machine for
I or 2 hours with the power switched on until it stabilizes at the
temperature of its operating environment.
g.H I-Bk: A different tape from the Hi8 is inserted. Use Hi8 tapes only.
E,kh 4n.t:
The tape inserted is too thin (less than 8 pm). Use P6/E6-120
(or PS/E5-90) or shorter tapes.
This shows the incident of error in the mechanics (the “8” is variable).
If this message appears, switch the power off. then witch it on again. If the message does not go out. repeat the on/off switching or try ejecting and reinserting the tape several times. If all attempts are of no avail, please amtact TASCAM or your nearest TASCAM dealer.
WARNING LED
This indicator lights to indicate the following :
0
Condensation on the head drum
0
Tape has broken DIGITAL i/O port accidentally disconnected
0
External clock not coming in correctly
0 0
No time code plug&in (when the opti~nai SY-88 is installed)
0
Time code setting not matched the type of incoming code
(when the optional SY-88 is installed)
If the indicator lights, check to see whether error messages
specify the problem in the display.
