2. REMOTE VOLUME- This control adjusts the audio level at the remote station.
3. SYSTEM VOLUME- Sets the program audio level throughout the system.
4. LOUDNESS- Compensates for the loss of bass and treble response the human
ear has when listening to audio at low volume levels by increasing bass and treble
response.
5. TREBLE- Adjusts the high frequency audio content of the source audio.
6. BASS- Adjusts the low frequency audio content of the source audio.
Setting Program Audio Controls
The volume level required at each station may vary with the location of the speaker and
the size of the room where the speaker is located. Spend some time experimenting with
volume levels, and adjust each speaker so that you can clearly hear the radio and
intercom. Use the following procedures to set your system’s volume level.
1. At each remote station, turn the volume control completely clockwise to maximum
volume.
2. At the master station, set the REMOTE STATION STATUS switches to the
RADIO/IP position.
3. Turn the MASTER VOLUME control to maximum volume.
4. Turn the SYSTEM VOLUME control on the master station to approximately one-third
volume.
5. Select an AM or FM radio station with a strong, clear signal.
6. Adjust the master station’s SYSTEM VOLUME control until you have enough
volume at the remote station that requires the highest volume (i.e. large living room,
family room, basement, etc). Note: The Master Station and all Remote Stations
(except the door speakers) are equipped with their own volume controls.
Although the Master Station SYSTEM VOLUME sets the SYSTEM’S volume
level, you may adjust an individual speaker volume level as desired.
7. Adjust the MASTER VOLUME control and all remote stations volume controls to
the volume level you desire. In order to have proper intercom audio levels, it is
recommended that the master volume and remote stations volume controls be set
at 2/3 or above.
