JACKALOPE - CNR/ACR multi-channel upgrade card
D
REVISION HISTORY: 1) 04/12/01 - Original release. 2) 06/27/01 - Changed C27,C28 from 10 to 220uF; Changed C22, C24 from 220 to 3.3uF; analog to digital ground connection on codec page; pull up/down on SPDIF output; changed +5VD_ACRC to ACR_5VD (Analog I/O)
D
SCOPE: Jackalope provides an upgrade to 4/6 channels on CNR or ACR equipped motherboards. Stuffing options allow for 2/4 channel operation for motherboards without onboard audio.

Note: Attenuation of the CDROM input is often useful since many CDROMs output signals larger than 1Vrms. If 0.0dB attenuation is desired, R13, R14, and R15 should be be changed to 0.0R, and R16, R17, and R18 should not be installed.
