3.4.2 Paging source (cont'd)

2. While speaking into the microphone, slowly turn down (to the left) the Page Trigger Level control (block 3) until

the amplifier disables paging and the LED in block 3 goes out.

Turn the control back to the right until the paging comes ON again.

3. Have the person stop speaking, but keep the push-to-talk button ON. The LED in block 3 should go out and the

music source should fade in.

4. Have the person resume speaking with the push-to-talk button ON. The paging source returns and the music

source fades out.

3.4.3 Page/music balance

Follow these steps to set the music and the paging levels.

1. Turn on Music Sources A and B.

2. Use the Remote Volume control to adjust the overall level.

3. Use the remote control to select Source A.

4. Have the person speak into the microphone. Adjust the Page Mix Trim (block 4) until the announcement is just

loud enough to be heard clearly. Be sure to set the paging level loud enough to be heard in noisy environments,

such as when a room is filled with loud patrons.

5. Have the person speak again, louder and closer to the microphone. If the Opti-voice

should reduce the gain, maintaining a reasonable level, and preventing audible distortion.

6. Switch to Music Input Source B. If Music Input Sources A and B levels are imbalanced, readjusting the settings

following the instructions in Section 3.4.1, "Music sources" may be necessary. If readjusting the Music Source

trims in block 6, watch the Music Compressor LED in block 7 to be sure it is not flashing red.

3.5 Monaural installations

If the music

source is...

Then...

Monaural

Use a "Y" connector cable to connect the source to both the L and R inputs. Then set this switch

to stereo (up).

Another option is to connect the source to the L input only. Then set the mono/stereo switch to

mono (down). The mono source will play at both L and R loudspeaker outputs. However, system

sensitivity will be reduced by 6dB. In this case, use a 400mV source level to reach full power. Most

sources will deliver 400mV at full modulation without a problem.

Mixed (1 mono

Use a "Y" connector to feed the mono source into both the L and R inputs. The stereo source is

and 1 stereo)

connected to the other source input. Set the mono/stereo switch to stereo.
