Installing Audio Devices

(See Appendix A2. Audio Option Specifications).

CrystalView models with the audio option use two standard 3.5mm stereo jacks on both the Local Unit and Remote Unit. They are labeled “LINE/MIC Out” and “LINE IN” on the Local Unit and “LINE/MIC IN” and “LINE OUT” on the Remote Unit. The “LINE IN” audio jack on the Local Unit is normally connected directly to the “LINE OUT” jack on the CPUs sound card. The “LINE OUT” jack on the Remote Unit usually connects to a pair of computer speakers or headphones.

To connect a microphone to the Remote Unit, connect the “LINE IN” connector on the Remote Unit to the Microphone. Connect the “LINE/MIC OUT” connector on the Local Unit to the “MIC” input on the CPUs sound card. The sound card should be set-up to provide an additional 20db of amplification. See your sound card manual for instructions.

If increasing the microphone amplification on the sound card cannot be done, or your microphone is not a powered microphone, you can use the built-in microphone amplifier located in the Remote Unit. * To set this, open the Remote Unit and locate the jumper labeled “MIC” on the PCB’s daughterboard. Reposition the jumper on the “MIC” jumper block pins to short the two terminals.

(See Figure 4 for location of “MIC” jumper)

* DO NOT install the amplification jumper if your microphone is already amplified.
