REAR PANEL

The rear panel contains the input connectors LINE, MIC.

XLR LINE INPUT

XLR Line input is a electronically balanced type with RF filter.
The knob LINE/MASTER controls the general output level of the distro.
The toggle switch PIN 1 LIFT remove the ground from the line input source.
The toggle switch INPUT SELECT is used to select between MIC or LINE input.
A yellow LED indicates which input is selected.

XLR MICROPHONE INPUT

Electronically balance inputs with RF filter.
Level control for gain up to 50db.
A limiter is used so the subsequent stage of amplifier will not be saturated.
Switch PAD attenuates the signal from the microphone 20 db.
Switch ¨Phantom¨ , provides 15 volts on pin 2-3 for condenser microphones.
LEVEL, provides gain adjustment for MIC amplifier.
Switch TONE, will activate a 800 hertz tone generator for calibration of output level.
A LED indicate that the tone is ON. The action of this switch cuts the signal going to the Master volume.

POWER SUPPLY

The DISTRO DJD 100 is equipped with Univeral Switching Power supply (90-240 Volts AC 47-64 hertz)

FRONT PANEL

The front panel contains all the connectors for the media to take the signal into the DJD 100
We see 16 XLR connectors, 4 jacks ¼ TRS, 4 BANANA Jack. For each of these output( except BANANA) we see a toggle switch to select the output level that the journalist needs for his recorder : MIC or LINE level.
Also a toggle switch call PIN 1 LIFT is used to isolate the ground between the DJD 100 and the media recorder. This becomes necessary when we have some HUM or ground loops problems.
We also find 4 RCA connectors for andy hook up to a cassette recorder. These outputs are –10db and they are not controlled by the master control level.

MONITORING

On the rear side of the DJD 100 near the VU METER, a level control enable you to listen on phone output and monitor on the VU, the signal on INPUT.
Indication on the VU BARGRAPH will be considered as a peak reading and the value on the meter as average.
On the front side of the distro DJD 100 an other Bar graph indicator monitor the output of the distro.
Two LED V+ and V- will indicate that the power supply gives a +/- 15 volts.

INSTALLATION

Place the DISTRO DJD 100 on a table for easy access for the journalists.
Connect the power cord to appropriate AC outlet.
LED’s V+ and V- in the back will turn ON, indicating that the DITRO in powered.
If you have an audio console, use a AUX out to feed the DISTRO into the line input.
Calibrate that AUX out for a 0 db on the console.
Position the INPUT SELECT switch on the DITRO to LINE, a yellow LED will turn ON besides that XLR connector.
You should read 0db on the VU meters. ( 0VU is equal to +4dbm on professional console and the DJD 100 is factory calibrated for unity gain) If not, adjust the screw driver trimmer to read so.(A additional 10 db gain is possible).
You have now calibrated you console with the DISTRO and the reading on the console is identical on the DISTRO.
If you use the MIC input on the DISTRO : Connect a microphone into the MIC connector.
Adjust the knob LEVEL of that MIC to read the VU meter around 0 db nominal.
A PAD switch will attenuate the signal level of 20db.
A PHANTOM switch will give a 15 volts on pin2 and pin3 on MIC input if you are using condenser microphone.
