Alpine 9861 low output
 

Hi all,

does anyone know how to maximize output via optical cable from an Alpine 9861 CD/DVD head unit to an Alpine 5-channel theatre amp (MRA-F350)? I have set the PCM output to +10 however the volume at max (35 on display) is nowhere near what I would consider full volume. The head unit does not seem to allow me to adjust the individual speaker volumes from the +4 that they are currently set at. Some of the songs on my MP3 DVD do play louder than others.

This unit seems quite complex with all of the settings that are available.

Any ideas??

Thanks in advance.

JJ
