Using Varispeed 55
D24—Owner’s Manual
Using Varispeed
The Varispeed function can be used to adjust the playback, recording, and rehearsal
speed in 0.05% steps from –6.00% to +6.00% (approximately ±100 cents, or ±1 semi-
tone). Increasing the speed has the effect of raising the pitch, while decreasing it lowers
the pitch. Varispeed can be set while the D24 is stopped or during playback, recording,
or rehearsal.
1Press the [VARI SPEED] button.
The VARI SPEED indicator lights up and the following display appears.
2Use the JOG/DATA dial to set the varispeed.
When Varispeed is set to something other than “+0.00,”
“VARI” appears in the FS window on the display, as shown
here.
Playback, recording, and rehearsal will now run at the specified speed.
Varispeed can also be set using the keypad. To enter a value of –2.90%, for example,
press [0/-], [2], [9], [0/-] and then press the [ENTER] button to activate the setting.
3Press the [VARI SPEED] button again to turn off the Varispeed function.
The Varispeed setting is stored when the Varispeed function is turned off.
You can toggle between varispeed and normal speed by pressing the [VARI SPEED]
button.
In addition to playback speed, varispeed also affects the sampling rate and wordclock
frequency. If the varispeed is set to –1%, for example, the sampling rate and wordclock
frequency decrease by 1%. So with the wordclock source set to internal 44.1 kHz, the
resultant sampling rate would be 43.659 kHz. Anything recorded at this rate will be
sampled at 43.659 kHz, not 44.1 kHz. Equipment that is wordclock synchronized to the
D24 will also be affected, although in most cases this shouldn’t be an issue. Some equip-
ment, however, may have trouble synchronizing to the D24’s wordclock at certain
varispeed settings.
When the D24 is used as a wordclock slave, the Varispeed function cannot be used
because the D24’s sampling rate is locked to the external source.
In a multiple D24 system, slave D24s follow the Varispeed setting made on the master
D24. See “Multiple D24s” on page 144 for more information.
