VU Meter

The VU meter shows the mix of both microphones and the tape

signal going out over the phone line or handset interface.

Send Side (To Phone Line)

There are separate volume controls for the two microphone inputs

and the line 3 input RCA jack. You can use all three inputs at the

same time. Mic 1 also has a Mic/Line 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 mix audio output level. The Line Out control adjusts the signal

going out of the balanced XLR jack marked Balanced Line Out. This

is either a mix of both sides of the telephone call at telephone band-

width (200 Hz - 3400 Hz) or a clean mic / line input mix at full band-

width (80 Hz - 16 KHz).

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.

Talkback Feature

A built in speaker lets you monitor the phone line during call setup

and station breaks. The monitor speaker volume is controlled by the

headphone volume control and has an additional on / off switch. An

internal push-to-talk microphone also helps when setting up your call.

The speaker switches off when the microphone button is pushed on

to prevent feedback.

Ringer

RemoteMix 3 / 3.m has an internal ringer for incoming calls.This can

be turned off using the switch on the side of the unit.

FAQ’s

? The output from Mic 1 is very low but the other two mics are fine.

! Check the position of the Mic/Line switch near Mic 1. This first input can

be switched to accept a line level signal from a mixer or other equip-

ment.

? I'm trying to use my RemoteMix 3 with a PBX system but it doesn't

seem to work. I've plugged the handset cord into the handset line

in jack but nothing happens. What's wrong?

! The "Handset (line in)" jack is for connecting a handset to the Re-

moteMix 3. The correct jack to plug the handset cord into is on the other

side of the unit labeled "handset cord". Just plug one end of the handset

cord into this jack and the other end into the existing telephone and dial

your call. Switch between the three different handset types on the ABC

selector switch if you're still having trouble sending audio down the

phone line.

? I've lost my power supply for my RemoteMix 3 unit. I have another

power supply that fits from a different product. Can I use this in-

stead?

! 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 out-

put with many combinations of voltage and available current. DC sup-

plies carry either positive or negative center pin output and may or may

not be "regulated". If you connect a negative center pin power supply 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 voltage of your DC power supply. All of our DC power supplies

have a low noise 5% tolerance. This means that our 9V DC power sup-

plies 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, 800mA power supply could actually out-

put 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 16VAC

power supply and a 1.5VDC power supply could both have the same

2.1mm jack.

? Can I wire a stereo mini output to the XLR input of a RemoteMix 3?

! Yes, simply wire the tip to pin 2, the sleeve to pin 1, and leave the ring

and pin 3 floating. You should use the mic 1 input since it is mic/line

switchable, and use mic 2 for an additional microphone.
