Section 4 Detailed Description of Unique CDR-1000 Features

Headphone Operation

1.With the transmitters and receivers setup and operating (see Sections 1 and 3 in the main RE-1 Operating Instructions), plug stereo headphones into the 1/4inch jack on the front panel.

2.The Selected Receiver LED will indicate receiver 1 is being monitored. Press the Receiver Select button once to change from Receiver 1 to 2.

3.Press the Receiver Select button once more and both indicator LEDs will light. You can now listen to both receivers. NOTE: If both receivers are set to the same channel, the volume will double.

4.Pressing the Select button once more cycles back to Receiver 1.

Audio Output

1.The CDR-1000 is equipped with a balanced XLR output for each receiver that can be switched between a fixed microphone level and an adjustable line level. There is also an unbalanced adjustable line level ¼” jack.

2.For microphone level operation place the Mic/Line switch in the Mic position. The level adjustment will have no effect on the output in the Mic setting.

3.For adjustable balanced line level operation place the Mic/Line switch in the Line position. The level adjustment will now affect the output.

Antenna Connections

1.Install the two FA-1 flexable antennas to the “antenna in” jacks on the rear panel.

NOTE: The two flexible ½ wave antennas included with the CDR-1000 can be remote mounted. For an additional 5dB gain use the LPA500 log periodic directional antenna.

2.The CDR-1000 is equipped with a left and right antenna output jack. These jacks can be used to connect up to 3 CDR-1000 (6 receivers) to two antennas without any additional equipment. DO NOT remove “dummy” loads unless connecting to another CDR-1000.

Antenna Chaining

3.Figure 3 shows the connection diagram for 3 CDR-1000 units.

4.Up to 12 CDR-1000 units can be operated with just two antennas with the optional APD4-B antenna distribution unit (see Figure 4).

12 Volt Power On “Antenna In” Jacks

To power in line antenna amplifiers, 12 volt power is available on the center pin of the antenna in jacks. this power is disabled when the CDR-1000 leaves the factory but may be turned on by the installer.

To turn on the 12 volts, first take off the cover of the radio by removing 14 screws. There is a 2 pin “header” and a “jumper” behind the “XLR” audio connector on each of the two large printed circuit boards. See Figure

5.The jumper is installed on one pin of the header at the factory. To turn on power, unplug the jumper and install it on both pins of the header.

CAUTION: Do not attach antennas and splitters with a DC short circuit to the antenna in jacks when the power is turned on. Damage could result to the splitter or CDR.

The following antennas and accessories may be used with power on:

FA-1, CLA-X, LPA-500B, APD4-B, APD4-1B, UAA-500

The following antennas and accessories may be used with the power off.

FA-1, CLA-X, LPA-500, APD4, APD4-1
