C. Connecting & using microphone paging
1.
Connect a 40 Watt or (less load) to the 70 Volt output or an 8 ohm load to the 8 ohm output. Only one
can be used at a time. Don’t attempt to use the 70 Volts and 8 Ohm outputs simultaneously.
2.
Turn all front panel controls to “0”. Note that the bass & treble controls are at mid range when at 0.
3.
Plug a good quality low impedance microphone with an on-off switch into the XLR microphone
connector on the rear panel and switch the microphone to on.
4.
Connect the DS1092 to a nominal 120 Volt 50-60 Hz source.
5. The green power LED should be lit at this time.
6. Set the master volume control to 10 (straight up).
7. Gradually increase the microphone level on the front panel while speaking into the microphone at a
normal tone of voice. Slowly increase the master volume if more gain is needed.
8. Adjust the bass & treble controls for the maximum intelligibility.
D. Connecting and using telephone paging
1.
Connect a 40 Watt (or less) load to the 70 Volt output or an 8 ohm load to the 8 ohm output. Only one
can be used at a time. Don’t attempt to use the 70 Volts and 8 Ohm outputs simultaneously.
2. Turn all front panel controls to “0”. (The bass & treble controls will be at mid range)
3.
Connect the DS1092 to a nominal 120 Volt 50-60 Hz source.
4.
Connect the balanced, dry (no battery or ringing voltage), output from your PBX to the screw terminals
on the DS1092 rear panel.
5. The green power LED should be lit at this time.
6. Dial the paging code on your phone system and slowly increase the page control on the front panel for
the desired level while speaking into the telephone.
