following way to show the level selected:
8.8 Meter modes
The DA-98 peak bargraph meters can be custom-
ized to suit your working preferences. Both the
peak hold time and the “ballistics” of the meters
can be adjusted.
8.8.1 Peak hold time
1) Enter menu group 2, move the cursor to
and press
ENTER
:
2) Use the
LEFT
and
RIGHT
keys to select the
parameter and the
UP
and
DOWN
keys to set the value for the peak signal level
hold time.
This value can be set to values between 0 seconds
(peak levels are not held at all) and 9 seconds.
There is another value,
, which will
permanently display the maximum peak signal
level. This can be useful if you are doing a “dry
run” rehearsal, but you cannot keep your eyes on
the meters all the time that the rehearsal is going
on.
You can also use the function keys in the number
key mode (see 5.2.2, “Using the function keys as
number keys”) to enter the peak time directly.
8.8.2 Meter ballistics
Use the same menu ( ) as
described above to change the “fall-back” ballis-
tics of the peak meters. You cannot change the rise
time of the meters, which are fixed with peak
meter characteristics.
1) Move the cursor to the
parameter
and use the
UP
and
DOWN
keys to select
between
, and .
8.9 Sine oscillator
The DA-98 incorporates a digital oscillator for
lineup and signal tracing purposes. This oscillator
is a sine-wave oscillator at either the standard tun-
ing frequency of 440Hz or the standard tape line-
up frequency of 1kHz.
The oscillator signal level is at the nominal signal
level of +4dBu (but note that since the oscillator is
a constant sine wave, it cannot truly be compared
with “real-world” transient signals).
To operate the oscillator:
1) Enter menu 2, move the cursor to
and press
ENTER
:
2) Use the
UP
and
DOWN
keys to turn the
oscillator between
, and .
When the oscillator is turned on, it overrides all
other track inputs.
8.9.1 Recording the oscillator
As mentioned above, the oscillator overrides all
other track inputs, regardless of whether digital or
analog input has been selected.
Recording the oscillator test tone is therefore sim-
ilar to any other recording operation.

NOTE
Any tapes produced with the TASCAM DA-88 or DA-
38 will conform to the TASCAM standard.
NOTE
To turn off the peak hold display if
has
been set, change the peak hold value to
seconds and
the meter segments will “drop back”.
WARNING
When using the oscillator, you should turn down the
monitor levels in the control room and studio to avoid
damage to your ears (and the speakers).
