Set-up and installation

The Nº28 incorporates RCA-type and XLR-type connectors for audio
signal input and output.
The Madrigal-designed RCA-type connectors used for single-ended
audio interconnection are a great improvement over ordinary RCA-
type connectors. The gold-plated XLR-type connectors employed are
of European design, and are made to professional application
standards.
When connecting the Nº28 to source equipment and power
amplifiers, we recommend Madrigal Audio Laboratories HPC
Interconnect Cable. HPC is available in various lengths, terminated
with RCA, XLR, and Camac connectors. See your Mark Levinson
dealer for more information.
The Nº28 offers internal gain adjustment of the line amplifiers, in 6dB
steps via two single-pole miniature rocker switches. These switches
have been factory-adjusted at 6dB/single-ended and 12dB/
balanced operation. In practice, you should have enough gain so
that normal listening is possible with the OUTPUT LEVEL set at
approximately 6.
If you wish to increase the line gain, see "Making the internal
adjustments;" refer to the table below for the proper switch positions
for each gain setting.

The Nº28 is available with either a high-gain or low-gain phono option.
Each option offers two internally adjustable gain settings via two
single-pole miniature rocker switches, one for each channel. The high-
gain and low-gain phono options have been factory-adjusted at the
lowest gain settings (58dB and 38dB, respectively).
If you wish to increase the gain, see "Making the internal adjustments;"
refer to the tables below for the proper switch positions for each gain
