JK Audio RM3
Phone Line / Handset Interface

RM3

RemoteMix 3 (formerly RemoteMix 3.m) is a combined phone line hybrid mixer and universal handset interface. We combined an audiomixer, headphone amplifier, telephone hybrid, and PBX telephone interface in one rugged unit. It’s perfect for remote broadcasts, sporting events, and field reporting from any location.

Simply plug the RemoteMix 3 into an analog phone line, connect a couple of microphones and headphones, and you’re ready to call into the station. In your headphones, you will hear a mix of both microphones and the line in jack, as well as the audio coming back from the other side of the phone call. This headphone mix also comes out the back of the unit on an RCA jack and an XLR balanced jack for PA system or tape deck feeds. The built in time-delayed peak limiter and VU meter help to control transmit levels, while the built-in push-to-talk condenser microphone and monitor speaker are a real help during equipment set-up and station breaks.

Universal Handset Interface - Ever get to a remote site that uses ISDN or a digital PBX phone system? You don’t have to worry any more. Simply unplug the handset from the existing telephone and plug the coily cord directly into the PBX jack on RemoteMix 3. Select the handset type with the three position switch and you’re ready to go. RemoteMix 3 can emulate electret, dynamic and corbon handset microphone types. This will allow you to use your professional microphones and headphones during the broadcast.

What happened to RemoteMix 3.m? The primary difference between RemoteMix 3and RemoteMix 3.m was the source of the signal on the Balanced XLR outputjack. We simply added a switch to select either clean mixer output or phoneline + mixer output. Now you can order one product and get ther functionality of both.

Features:

• Two XLR Microphone Inputs with independent level controls. Mic 1 input is mic/line switchable.

• RJ-11 Jack for use with conventional phone lines. Also has an auxiliary handset input for use as a standard telephone. Handset jack is biased for electret microphone types.
• Time Delayed Peak Limiter and VU Meter help to control transmit levels. The peak limiter has a three second delay before clipping any audio. This allows for normal speech patterns as well as brief exclamations to be broadcast unhindered.
• Push to Talk Condenser Microphone and Monitor Speaker are a real help during equipment setup and station breaks. Microphone push button mutes speaker to eliminate feedback and switch disables speaker entirely after setup is complete.
• Two 9 Volt Batteries will power the unit for 36 hours. The batteries are installed parallel so the unit can run on only one battery if necessary. An AC adapter is also included with the unit.
• DTMF/Pulse Keypad for dialing out. Tone/Pulse switch located under the battery door.
• Keypad Lockout Switch so accidental key presses are not blasted down the phone line during a broadcast.
