Operation
IFB
If using the phone line or handset interface for an IFB feed, the balanced male
XLR output may be used to feed an IFB earpiece or other device. If using the
1/4” cue input / wireless adapter jack for the telephone connection, the IFB feed
must be taken from one of the 1/4” headphone jacks. This also applies if you are
planning to record both sides of the conversation while using the 1/4” wireless
adapter jack for the telephone connection.
Power
RemoteMix 4 is powered by two 9 volt alkaline batteries located on the side of
the unit. The red <Power> LED on the front of the device will gradually dim as
the battery runs down, then extinguish about a half hour before the unit shuts
down. Since these two batteries are in separate drawers and wired in parallel,
you can hot swap one battery at a time so you never lose power.
It is important to replace both at the same time with identical batteries. If two
fresh batteries are not available, it is better to run using only one good battery.
Since the battery fixtures are wired in parallel, it does not matter which one gets
the single battery.
We also provide a high quality, regulated AC to DC adapter to power
RemoteMix 4 when AC power is available. Simply plug it into the back of
RemoteMix 4 and plug the transformer into a wall outlet. This is a switching
power supply so you can connect to a 110 or 220 VAC power source. When the
power connector is inserted into the jack, the batteries are bypassed. The AC
adapter does not charge the batteries. If you lose power during your broadcast,
the RemoteMix 4 automatically reverts to battery power so your broadcast will
not be interrupted.
Make sure you use only the supplied AC power adapter with the
RemoteMix 4. Using any other adapter could damage the unit.
WARNING! It is strongly recommended that this product be connected
to an adequate surge protection device for the power line as well as the
telephone line at all times.
