Connecting the output of Chime Master carillons to PA systems for inside sound is easy once you determine the type of input you are connecting to. Dealing with impedance mismatches, ground loops and running cables a long distance, are addressed here. The best way to connect any instrument to a PA system with a professional mixing desk with balanced inputs is with a "direct box." Running long wires to connect to a PA with unbalanced inputs is generally a bad idea, but you may achieve acceptable results by following the balanced cable approach. | <div style="font-size:84%">'''[http://www.ChimeMaster.com Home] > [[Chime_Master_Help|Help]] > [[:Category:Installation|Installation]]'''</div><br /> | ||

Advanced eXpericence carillons provide balanced line level audio outputs on 3.5mm Euro-plugs. | |||
If you are connecting to an amplifier with an unbalanced RCA or quarter inch jack, connect the internal coaxial wire to the positive terminal and the shield to both the Ground and negative terminals. | |||

Monitor 1 outputs the same signal as goes to the left front panel speaker. Monitor 2 outputs the right front speaker signal. These monitor outputs are not affected by the speaker level/mute icon at the top of the screen. The output levels are set in Settings > Volume and can mix the left and right channels together for each output or maintain stereo separation. | |||
'''Millennium and Bravo''' | |||
OUT A is the monitor output for these systems. OUT B is for the outside audio system. | |||

Balanced audio output is available on pins 2 and 3 of the DIN-4 jack (the pins closest to the notch). | Balanced audio output is available on pins 2 and 3 of the DIN-4 jack (the pins closest to the notch). Unless otherwise labeled, this output has a high-pass filter because it typically is used to drive a remotely located tower amplifier. It also is not affected by the carillon's monitor level controls. | ||
Pin 1 has a switched 12V through a 220 ohm resistor to enable power to the amplifier and Pin 4 has a 220 ohm resistor to ground (for enable current only). We provide cables to connect these DIN plugs to QSC amplifiers with 15-pin D connectors for balanced audio and power switching. Junction boxes with 4-pin DIN male and female jacks and screw connectors can be used to extend a 2-pair shielded cable to remote amplifier locations. | |||

These systems have a | These systems have a high impedance pseudo-balanced output with a 330 ohm resistor from the op-amp output to the Inside jack tip, another 330 ohm resistor from ground to the ring, and the sleeve is grounded to the chassis. It is recommended that a balanced line input from the mixer be tied only to the tip and ring, leaving the shield connected only to the mixer input ground. | ||

Sometimes the mixer will only have a microphone input using an XLR connector. In this case, a direct box with a line input is recommended. The box takes care of converting unbalanced to balanced and high to low impedance. It will also reduce the gain of the signal (through the Line input jack) so it doesn't overload the microphone preamp in the mixer. Place the direct box next to the Chime Master carillon and run a balanced cable (two conductors and shield) the distance to the PA mixer. | Sometimes the mixer will only have a microphone input using an XLR connector.

Decent direct boxes are available for less than $50. Always choose a passive transformer-isolated direct box that does not require batteries or phantom power. The input jack should be plastic and isolated from the chassis ground. | Decent direct boxes are available for less than $50.
