RemoteMix 4 Portable Broadcast Mixer User Guide JK Audio
Introduction RemoteMix 4 is a four channel field mixer combined with a four channel headphone amplifier. It includes a telephone line hybrid and keypad, as well as a universal PBX handset interface and a 2.5 mm wireless phone interface. All this comes in a tough, portable unit that's smaller than a lunch box. These parts were designed to work together and save setup time in the field. There is no need to send an engineer with patch cables. All the pieces work together in one reliable unit.
Connection 1. Mic inputs 1 and 2 are balanced XLR jacks with low-noise amplifiers. 2. Mic inputs 3 and 4 are balanced XLR jacks with low-noise amplifiers. A mic/line selector switch adds a 40 dB pad for a line level balanced input. A switch on each of the 4 XLR mic inputs will provide 48 V phantom power. If inputs 3 or 4 are set to Line input, the 48 V will not be present at the XLR jack even if the switch is left on. 3. The stereo 3.
Connection 1. Connect your audio equipment, microphones, cue input, and headphones to the input and output jacks on RemoteMix 4. 2. (a) Connect the jack marked "Phone Line" to any standard analog telephone line, or (b) Disconnect the handset on an existing telephone and plug the coily cord from the phone into the Universal Handset Interface jack on RemoteMix 4, or (c) Connect the Wireless Phone Interface jack to the headset jack on your cellular telephone using the supplied JK Audio interface cable.
Operation Phone Line The RemoteMix 4 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. 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, or a key telephone system, you can use the built-in handset interface.
Features Mic Level Controls Each of the four XLR inputs has a level control knob with a separate red Clip LED to indicate clipping on each channel. If you see more than an occasional flash of the Clip LED you should decrease the level for that channel. Master Level Control The Master control knob will set the overall level of the sum of all the mic and line inputs. The LED meter for the master audio level ranges from -30 dB to +3 dB.
Features Bluetooth Wireless Technology This multi-function switch activates the Bluetooth Wireless Technology. The blue LED directly above this switch indicates when it is on. See pages 10-11 for more information. Bass Boost With this switch turned on, the Master Output audio will be sent through the Bass Boost before being routed to the telephone circuits. Keypad ON / OFF This switch disables the DTMF keypad to prevent unwanted tones from being transmitted down the phone line during a broadcast.
Features 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.
Features 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.
Connecting—Bluetooth Wireless Technology Establishing a Bluetooth connection varies with different cell phones. On your phone, find and select the option to set up a connection. Monitor the Bluetooth audio path on headphones in the "Return" position on the RemoteMix 4. Pull up on the Bluetooth multi-function switch on the front of the RemoteMix 4 and hold for approximately 5 seconds. You will hear a beep in your headphones, followed by a second beep or beeps.
Connecting—Bluetooth Wireless Technology Now go to your Bluetooth device and search for Bluetooth connections. If this is the first time you have paired with this device you will first need to select the option to add an audio device. Wait until the cell phone has found the new Bluetooth device. Select from the list the ID of "JKRM4xxx" where “xxx” corresponds to the last 3 digits of the unit’s serial number. Enter “Yes” when asked to “Bond” with this device. The pin is "0000".
FAQs ? ! 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 first 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 10 of this User Guide for detailed information.
FAQs ? ! Why doesn't my RemoteMix 4 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 4. This red LED flashes when a call comes in. The Ring indicator is located directly below the keypad on the front of the unit. ? ! Will any cellular telephone work with RemoteMix 4? The wireless interface on the RemoteMix 4 works very well with most cellular telephones.
FAQs ? ! 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. ? Does the AC power supply charge the batteries? ! No.
