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
2) Use the and
LEFT RIGHT
parameter and the
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,
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.
NOTE
To turn off the peak hold display if
been set, change the peak hold value to
the meter segments will "drop back".

tics of the peak meters. You cannot change the rise
time of the meters, which are fixed with peak
meter characteristics.

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 and

oscillator between
When the oscillator is turned on, it overrides all
other track inputs.
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).

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.
