Phone Line Connection
7. Phone Line
The RemoteMix 3.5 has an RJ-11 jack that can be connected to any
standard, single line analog telephone line. This jack should not be
connected directly to digital PBX or ISDN phone systems.
8. Handset Interface
If you do not have access to an analog phone line or if the phone system
is a digital or analog PBX, ISDN, VOIP or a key telephone system, you
can use the built-in handset interface. Disconnect the telephone handset
from the coily cord and plug the cord into the RemoteMix 3.5 <Universal
Handset Interface> jack. Now select the handset type on the 3 position
switch.
Trial and error works faster than a chart of handset types, but this basic

9. Cue Input / Wireless Phone Interface
RemoteMix 3.5 comes equipped with a <Wireless Phone Interface> built
in to the 1/4” <Cue Input>. This 1/4” wireless interface accepts a specially
designed 1/4” to 2.5 mm or 1/4” to 3.5mm cable provided with the unit.
This interface works with any wireless phone or notebook that accepts
standard third party headsets and earpieces. Some wireless phones have
the standard 2.5 mm TRS jack while others have a 3.5 mm TRRS jack and
others yet have proprietary jacks. Adapters to convert the proprietary jack
to a standard 3-conductor 2.5 mm or 4-conductor 3.5 mm jack are available
for most wireless telephones through their dealers, local electronic stores or
many internet stores.
10. When using the wireless interface, it is important to keep your wireless
telephone 12” - 24” away from the RemoteMix 3.5 and any microphone or
headphone cables. This will help prevent unwanted RF noise from entering
the unit.

Getting Connected
Setting Up
1. Connect your audio equipment, microphones, cue input, and headphones to
the input and output jacks on RemoteMix 3.5.
2. There are 4 ways to connect the RemoteMix 3.5 to the phone line:
A. For Analog Phones: Connect the jack marked <Phone Line> to any
standard analog telephone line, or
B. If there is no access to an Analog Phone Line: Disconnect the
handset on an existing telephone and plug the coily cord from the
phone into the <Universal Handset Interface> jack on RemoteMix 3.5,
or
C. If there is no Land Line: Connect the <Wireless Phone Interface>
jack to the headset jack on your cellular telephone using the supplied
JK Audio interface cable.
The 1/4” Wireless Interface jack also serves as a <Cue Input> that
feeds the headphones. Connect any line level output here, such as the
output from your personal audio player. This signal does not reach the
XLR output but will be present on the right channel (return) of the
stereo output.
D. Bluetooth Wireless Technology. See page 8.
Making a Call
There are also 3 ways to initiate an outbound call with the RemoteMix 3.5. First
turn on the power switch and ip the <Phone Line> switch to Dial/Talk.
A. When connected to an analog line: Flip the <Keypad> switch to
On and dial your call. You are now ready to broadcast or record a
telephone interview.
B. When connected via the Universal Handset Interface on the
RemoteMix 3.5: Take the handset off of the cradle of the phone you are
connected to and dial with the keypad on the base of that phone. The
handset must stay off-hook for the duration of the broadcast or the call
will be disconnected.
C. When connected via the 1/4” Cue Input / Wireless Phone Interface:
Dial the call with your cellular phone handset. Audio will automatically
be transmitted and received through the RemoteMix 3.5 audio inputs
and outputs. The phone’s internal speaker and microphone will be
disabled during the call. Feel free to leave your phone connected to
power throughout the broadcast to conserve battery power.

RemoteMix 3.5™ Broadcast Field Mixer
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 3.5 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 xtures 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 3.5 when AC power is available. Simply plug it into the back of
RemoteMix 3.5 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
adapter does not charge the batteries. If you lose power during your broadcast,
the RemoteMix 3.5 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 3.5. Using any other adapter could damage the unit.

FAQs
1) Why do I keep getting an error message when I try to pair
with my Bluetooth enabled cell phone?
There is a difference between Idle Mode and Pairing Mode. The rst time
you make a connection with a new Bluetooth enabled device, you must be in
Pairing Mode. Please read carefully through the instructions on page 8 of this
User Guide for detailed information.
2) What is the range of the Bluetooth transmitter/receiver?
The RemoteMix 3.5 will transmit and receive audio signals up to 33 feet
from your Bluetooth device. The maximum range of this product is achieved
when a clear line of sight is maintained between connected devices, but may
also be limited by interference due to the environment. While this product
offers extended range capabilities, maximum usable range is limited by the
weaker of the two paired/connected devices. Transmitting signals over longer
distances will require more power, therefore you should keep RemoteMix 3.5
as close as possible to your Bluetooth device to conserve battery power.
3) How long will the batteries last in my RemoteMix 3.5?
There are many variables that affect battery life, such as the number of
headphones, and the use of Bluetooth. All of our battery life tests included
3 headphones playing music at average listening levels. These tests use
standard alkaline batteries. Lithium batteries can add 3 to 4 times the battery
life, at 3 to 4 times the cost.
The following numbers are from lab tests and may not represent your usage:
7 hours of broadcast through a cell phone using Bluetooth Wireless
Technology at a distance of 1 meter.
10hours of broadcast through the phone line hybrid, using dynamic
microphones.
4) Why doesn’t my RemoteMix 3.5 ring when a call comes in?
The audible ringer found on some of our other RemoteMix units was replaced
with a visual ring indicator on the RemoteMix 3.5. This red LED ashes when
a call comes in. The Ring indicator is located directly below the keypad on the
front of the unit.
5) Will any cellular telephone work with RemoteMix 3.5?
The wireless interface on the RemoteMix 3.5 works very well with most
cellular telephones. However, some wireless telephones generate excessive
RF noise which can be heard as a “chattering” or “motor boat” sound.
The noise from these particular telephones will be unacceptable for most
broadcast applications. Also, some wireless phones have the standard 2.5
mm headset jack while others have a 3.5mm stereo headset jack and others
have proprietary jacks. Adapters to convert the proprietary jack to a standard
3-conductor 2.5 mm jack or 4-conductor 3.5mm jack are available for most
wireless telephones through their dealers, local electronic stores or many
internet stores

RemoteMix 3.5™ Broadcast Field Mixer
FAQs
6) What kind of device can I connect to the Cue Input?
Setting the switch for the dual-purpose 1/4” input to Cue Input will provide
a standard line level input for connection to another audio device, such as
a portable radio. The audio signal will be sent to all three of the headphone
outputs. This way, your announcers can listen for a cue from their radio
station at the end of a station break.
7) The cellular interface cable was left behind at our last event.
Can I get a replacement at our local audio supply store?
This is a custom made cable and is not wired the same as those that may
be available at your local electronics store. Please contact your JK Audio
dealer or our Customer Service department and ask for either a CN045 or a
CN113 replacement cable. The CN045 has a 2.5mm TRS headset plug and
the CN113 has a 3.5mm TRRS headset plug. Most newer phones, especially
those that include a mp3 player, have a 3.5mm TRRS headset jack and
therefore require the CN113 cable.
8) The output from Mic 3 is very low but the other mics are ne.
Check the position of the <Mic/Line> switch near <Mic 3>. This input can be
switched to accept a line level signal from a mixer or other equipment.
9) How can I tell how much battery life is remaining?
The red <Power> LED functions as a battery life gauge that will gradually dim
as the battery runs down. This red LED will go completely dark about a half
hour before the unit shuts down. Keep in mind that the VU meter, Bluetooth,
and clipping LEDs will remain bright until the unit stops functioning.
10) Does the AC power supply charge the batteries?
No. You may use rechargeable batteries, but you must remove and recharge
the batteries outside of the RemoteMix 3.5.
11) I’ve lost my power supply for my RemoteMix 3.5 unit. I
have a power supply that ts 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. Most consumer power
supplies are not regulated. This could invariably damage your equipment,
and also create a great deal of noise. Our products are designed for and
tested with their respective power supplies for optimum operation. If you
have lost your power supply, please contact your JK Audio dealer or our
Customer Service department and ask for a PS009 power supply for your
RemoteMix 3.5.
