Installation of the S100 RIAA Phono Module into the NAD S100 pre-amplifier.

Before installation, make sure the correct settings for the cartridge have been selected.
The module is factory-set at MM; 35dB gain; 47kohm, which will suit most Moving Magnet
(MM) cartridges. Refer to chapter “Changing settings of S100 RIAA Phono Module” if you
need to change the internal settings of the module. To install the module:

• Switch power off to the entire system.

• Disconnect the mains from the NAD S100 pre-amplifier.

• Using the correct size Allen key (3mm), remove the top 3 Allen/Hex bolts at the S100

back panel. Keep the bolts in a safe place.

• Gently remove the S100 top-cover panel by first sliding the panel slightly backwards
and then lifting upwards.

• With the controls (volume, input buttons, etc) facing towards yourself, you will notice
the space reserved for the NAD S100 RIAA Phono Module in the top right-hand
corner. The 3 holes in the Printed Circuit Board (PCB) correspond with the 3 legs on
the module.

• Being careful to orientate the Module’s legs into the 3 corresponding holes in the
PCB, insert the module into the space reserved. Push the module gently home. Note
that this requires little force.

• Once the Module is in place, replace top cover panel.

• Remount Allen bolts.

• Connect the turntable’s plugs to Phono inputs.

• Connect S100 pre-amplifier to mains again.
