Talk over the project with the customer. Find out when you will have access to t he bu ilding. Before y ou start be sure you have a complete understanding with the customer: Where the transmitter will go Where the transmitter could go if the first choice will not work Where the studio is to go Other places the studio could go. How the wire will be [...]

Generally the deeper your rod, the lower the resistivity will be. Bury any horizo ntal wires, the more g round/dirt contact the better. Just an i nch or two below the surface will do. You can use a flat bla de shovel to create a “trench” that t he wire can be laid into. This works well with lawns. It is best to bury your rods en tirely if possi[...]

NO!!!NO!!! Do you see h ow the tra nsmitter is m ounted ri ght next to t he house? It is not above all building s, the antenna is not in the open air, als o look at the a ntenna, it is right up against the siding!! NO!! Even if this does work a little, rang e will be very low in the direction of t h e house. This transmitter needs to be moved up so[...]

Connections for balanced au dio in. These con- nections should be the same for other audi o processors. From the audi o source, if the connector is an XLR connector you would use pins 2&3 . Pin 1 is ground, don’t use that. If the connector for the balanc ed audio to t he 222 is a 1/4” stereo jack use the tip and ring con- nections, again do[...]

Unbalanced au dio is a signal with a ground r eference, us ually a center wire with a outer ground, like a RCA jack, or coax cable. The center is the si gnal (hot) wh ile the outer is the (ground) reference and shield. Here is the 222 wire diagram showing the i nput in the unbalanced method. This coul d be a 1/8 ja ck plugged into a computer sound [...]

Wire diagram for the transm itter system. There are two term inal blocks, either can be used. Not shown is the cable shield drain connection, connect it to the GND terminal on the terminal block in the transmitter. Be careful not to connect the po we r or audio to the (S+) or (S-) terminals, these are used for another function (RS485 sync). 11[...]

There are 3 test hole pads o n the unit (see dia- gram). Take a standa rd voltmeter that is set to DC 5-20 volts and plug it into the botto m and top test hole pads. The black lead[...]

The transmitter should sound as loud as others on the dial , if it doesn’t there is a problem. It may be an audio impedance m ismatch, or the level m ay need to be turned up. If the audio level isn’t high enough you won’t get good range, audio is a gate on the power, keep your au dio turned up as high as you can . We have foun d the most com [...]

A typical encounter wit h the FCC would entail just a phone cal l from them asking for your cert ifica- tion number. Most of the time (as l ong as you are using a certified transmitter) they won’t even come by to inspect your inst allation. You don’t want to be using an uncertified transm itter (especially a kit) if you get a call from the FCC.[...]
