INSTRUCTION MANUAL
DIP switch settings
Thank you for your purchase of the AD-60 Analog Disc Input Board. This board ts into an
option slot on your amp, enabling playback from analog players.
This board includes a 6-pin DIP switch that controls up to three settings, labeled ❶, ❷,
and ❸below. On some amp models, the MC/MM selection (❶) is operated directly from
the amp’s control panel. On these models (see below), the DIP switch setting for ❶is
meaningless. Please refer to the table below, and set the DIP switch accordingly.
Analog Disc Input Board AD-60
In general, the MC input impedance should generally
be set to at least 2 or 3 times the cartridge’s internal
impedance. Listen to the sound at various settings,
and select the setting that sounds best.
This lter attenuates frequencies below 25 Hz, at a
slope of -12 dB/octave, removing subsonic noise
that might otherwise interfere with the quality of
the reproduced sound. This lter can be extremely
effective when you are playing very warped
records, or where subsonic frequencies are causing
distortions in your woofers. We recommend that
you make active use of this feature.
❸Subsonic lter ON/OFF

How to install
1
Switch off the power to the amp.
2
On the rear panel, remove the sub panel of the slot
you wish to use. (See
Fig. 1.
)
◆Retain the sub panel for future use.
3
Insert the board into the slot, aligning the board with
the upper and lower guide rails Fig. 2. . Gently push in
until the board connects with the connectors at the rear
of the slot. When fully inserted, the board panel will be
ush with the amp’s rear panel.
4
Fasten the board in place with the two screws.
●
Be sure to turn off the power to the amp before inserting or removing the board. Leaving power on
may result in equipment failure.
●
Do not put anything other than the board into the slot. Inserting ngers or objects may cause
equipment failure.
●
Do not touch the board’s components, soldered areas, or connector pins, as doing so may cause
equipment failure. Hold the board at the edges or by its panel.
●
Tighten the screws securely, by hand. Failure to tighten screws may result in equipment failure.
●
Never apply contact enhancers or conduction enhancers to connectors or terminals. Use of these
materials may result in equipment damage.
