I need help hooking up Merlin vsm mme Bam to avr

If it has a tape or external processor loop, but the BAM in the tape loop.

You can hook the pre-amp out to the BAM in and the BAM out to the amp in. Or you can put it in the tape loop if the AVR has one.

Since you have a receiver (pre-amp, tuner, amp on one chassis), the BAM output is going to go to the CD input on the receiver, which directs it to the pre-amp section of the AVR and then the amp section. Assumming CD is your only source. For more than one source, insert it into the tape loop as Brf says, or insert btwn the pre-amp and amp section of the receiver, if there is a pre-out and a main amp in.

For use w one source, connect output of your CD player to BAM input using RCA cables. Connect BAM output to CD input on the AVR using RCA cables. Select CD input on AVR and enjoy.

You're welcome, Tesseract86. Enjoy!!

It does not appear that your AVR has a tape loop, so you will have to insert the BAM between your source and the AVR. CD output to BAM input, BAM output to CD input on AVR.
