When sync is present, DAFV
2
waits until the next field edge (1/2 frame) before
executing a command received from an edit controller.
If sync is not present, the DAFV
2
automatically switches to an internal crystal-
generated clock. Accuracy is guaranteed, but field edge alignment is not. Under most
situations, this is not important for audio editing, since the maximum error is 18
milliseconds.
Power
Connect the power supply to the power jack in the rear of the DAFV
2
. The supply is 9
VDC at 500 mA (1/2 Amp), center positive. When the unit is powered up an LED is
lit next to the power switch.
Special Notice about AC Line Conditioning:
All microprocessor-based equipment (including VTRs, switchers, and audio processors)
must be protected from variations in the AC line. The DAFV
2
is no exception. Power
surges, lightning strikes, “brown outs”, even nearby motorized equipment can scramble
computer memories and in some cases even cause damage to the hardware.
It is strongly recommended that all your computer-related equipment be plugged into
an AC line conditioner. Multiple-outlet power strips usually have circuit breakers,
some have surge suppressors. But ideally the system should be protected with a power
conditioner that includes both surge suppression and line filtering. Being plugged into
conditioned power should protect the mixer, edit controller, switcher, VTRs, and DAFV2.
Audio Hookup
You may connect the output of several audio sources to your mixer, such as VTRs,
DATs, Microphones, and CDs.
The individual VTR audio outputs are connected to the mic/line inputs of the mixer,
using (up to) the first 16 channels.
These channels will need to be bussed as needed to route the audio path to the various
outputs for monitoring and recording.
Refer to the operations manuals for your specific mixer for details.
