Hello Bose - Just received the PAS and experimenting with it. The clarity is amazing - I've had some very good comments from the 1st gig I did with it. I have a solo act with tenor and alto sax and use backtracks from a small portable CD player. The backtracks are critical to my act. Two things:
1). When I use a combiner jack to combine the L and R signals from the CD player into a mono signal to put into PAS channel 3 or 4, in some songs I lose certain instruments almost totally- ex: a song with a piano intro - the piano is so soft compared with the other instruments its almost not audible. When I connect the L and R signals into channels 3 and 4 directly this problem goes away. Am thinking of getting a cheap mixer so I only have to use one PAS channel for the CD player - any thoughts on why this is happening? Any other suggestions?
2). Problems with warmth and Bass response. At first when I plugged in the CD player I got all higher and some mid frequencies but almost no bass at all. I have a "DBB" (Dynamic Bass Boost) on the portable CD player - when I engage this the sound warms up and the bass appears. The strange thing is I did not have to do this with my previous PA system (Peavy Escort). There are other songs where the DBB causes too much distortion and I have to turn it off - but when I do I have no bass at all - the sound gets high and thin. I'm forced to choose between distortion or no bass. I'm concerned that this CD player's special feature (DBB) is necessary to get my tracks to sound good with the PAS - any ideas as to why this is happening?
