10. Tip the Nº30 onto its side again and carefully slide the top cover
into place.
11. Replace the eight screws securing the top cover.
The Nº30 incorporates RCA-type and XLR-type electrical connectors,
and EIAJ-type and ST-type optical connectors for audio signal input
and output.
For analog audio interconnection, we recommend Madrigal HPC
Interconnect Cable. HPC is available from your Mark Levinson dealer,
in various lengths and terminated with RCA, XLR, and Camac
connectors.
For electrical digital interconnection, we recommend Madrigal MDC
cable. MDC-1 Pro is designed for AES/EBU interconnection (via XLR-
type connectors); MDC-2 FatBoy is designed for SPDIF interconnection
(via RCA-type connectors). HPC is available from your Mark Levinson
dealer, in various lengths and terminated with RCA and XLR
connectors.
If connecting a digital source which provides only an RCA-type digital
output, it's possible to use an RCA-to-XLR cable for connection to one
of the Nº30's XLR-type digital inputs.
For the best performance, we recommend using a high-bandwidth
(up to 300MHz), three-conductor, 110
Ω
cable such as Madrigal MDC-1
Pro (available from your Mark Levinson dealer). You may also fashion
one according to the diagram below.

cable, including a 237

resistor as close
as possible to the XLR termination may, in some cases, improve sonic
performance; follow the diagram below.
