JK Audio RemoteMix C+ - Manual (Page 4)

Send Side (To Phone Line)
There are separate volume controls for the two XLR
microphone inputs and the RCA line input (To Phone Line)
jack. You can use all three inputs at the same time. Mic 1
also has a Mic/Line
level selector switch
which lowers the gain
on the Mic 1 XLR
jack by 30 dB to
allow a balanced line
level input.
Receive Side (From Phone Line)
The receive side has separate controls for headphone output
level and line output level. The Line Out control adjusts the
signal going out the RCA and XLR jacks marked From
Phone Line. This is a mix of both sides of the telephone call.
Headphones
The built-in headphone amplifier is strong enough to power
two pair of headphones or a small desktop speaker. The left
and right channels contain the same mono signal, but are
powered by separate amplifier channels. These jacks will
drive either two 1/4” stereo plugs or two 1/4" mono plugs.
Handset Jack
The handset jack on the side
of RemoteMix C+ allows you
to plug in a telephone handset
and quickly set up a call before
you connect your microphones
and headphones. The handset
m i c r o p h o n e v o l u m e i s
adjusted using the Line In knob. The earpiece volume is
adjusted using the Headphone level knob. All telephone
handsets are different, so if yours is not compatible, try an
AT&T, Sony, or Radio Shack residential phone handset.

FAQs
? Can I use the RemoteMix C+ with a digital PBX phone
system if there is no analog line available?
! No. If you need compatibility with digital PBX or ISDN phone
systems you should step up to a RemoteMix 3 or RemoteMix
Sport. These units will work virtually anywhere.
? Will RemoteMix C+ provide phantom power for my con-
denser microphone?
! No, this device will not provide phantom power. If you are
connecting your microphone directly to a JK Audio Remote
Mix C+, you should use a dynamic mic.
? I've lost the power supply for my RemoteMix C+ unit. I
have another power supply that fits from a different
product. Can I use this instead?
! NO! Never use a power supply other than the one that was
supplied by your manufacturer. Power supplies are available
in either AC or DC output with many combinations of voltage
and available current. DC supplies carry either positive or
negative center pin output and may or may not be
"regulated". If you connect a negative center pin power sup-
ply to a positive center pin jack, it's just like hooking up the
battery cables to your car backwards. Obviously you would
not want to do this to your car or your expensive audio
equipment. "Regulation" is the tolerance to the specified volt-
age of your DC power supply. All of our DC power supplies
have a low noise 5% tolerance. This means that our 9V DC
power supplies will always output 9 volts +/- 5%, whether
you are using no power at all or applying a full load. Most
consumer power supplies are not regulated. A non-regulated
9V, 800 mA power supply could actually output 16V until an
800 mA load is applied. This could invariably damage your
equipment, and also create a great deal of noise. There is
also no standard for the size of your power jack. This means
that a 16V AC power supply and a 1.5V DC power supply
could both have the same 2.1 mm jack.
