7> Close the console and refasten it.
If you do the above then restart the console without selecting “Start
the System”, you may not be able to get the console to run. Use the
following procedure to start the console. This procedure is also another
way to get into AVOS mode.
1> Turn off the console and open as described above.
2> Fit the AVOS link. On Borris 3 motherboards this is in the bottom
right corner by the 4-digit display. On earlier boards it is located
near the chip labelled “PASHA”. It is in a row of 8 jumpers, the
AVOS link is the one nearest the back of the console. A link is
provided fitted to one of the pins. Fit the link so it connects the
two pins.
3> Close the console (don’t fasten it), then turn on the power.
4> The console will power up in the AVOS menu.
5> Select A [Start the system]. Do not select any other option.
6> Turn off the Pearl, open it and remove the AVOS link (fit to one of
the pins only).
7> Close the console and refasten it.
The location of the links on the motherboards are shown on the next
page.
13.1.10 Audio gain links
You can change the sensitivity range of the audio input using the Preset
Gain Links.
The links are located near the audio connector. On the Borris 3
motherboard they are labelled L14, L15, L16. Link L16 for 0dB, L15 for
20dB and L14 for 40dB
On older motherboards they are labelled “Preset Gain Links” and the
gain for each link is printed on the board.
The link should normally be set to 0dB for speaker level, 20dB for line
level input, 40dB for a microphone level input.
