Mark Levinson DUAL MONAURAL PREAMPLIFIER N26 - Manual (Page 13)

Set-up and installation
The Nº26 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 standards.
When connecting the Nº26 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 Nº26 offers internal gain adjustment of the line amplifiers, in 6dB
steps via two four-pole miniature rocker switches (one for each
channel). These switches have been factory-adjusted at the lowest
gain position (6dB of line gain in single-ended operation, and 12dB of
line gain in 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.
Switch Gain
#1 #2 #3 #4 Single-Ended Output Balanced Output
On On Off Off 18dB 24dB
Off On On Off 12dB 18dB
Off Off On On 6 dB 12dB
The Nº26 is available with either a high-gain or low-gain phono option.
Each option offers two internally adjustable gain settings via two two-
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
settings.
