How to Operate the MP100

Power On and Off
The Red LED above the STANDBY/ON Push-button
lights to indicate the MP100 is in Standby mode. To
switch ON the MP100, press the STANDBY/ON Push-
button on the Front Panel.
Note: When the MP100 PWR CTRL (Power Control)
TRIGger INput is connected to other components
with a Power Control (Trigger) Out, the MP100
will automatically go On/Off. Refer to pages 10 and
11 for additional information.
Power Mode
The MP100 incorporates an Auto Off Feature, which
automatically places the Phono Preamplifier into the
Power Saving Standby/Off Mode. This occurs approx-
imately 30 minutes after there has been an absence of
user activity (includes changes to any of the Opera-
tion Functions such as Input selection, Digital Output
selection, etc) or absence of an audio signal. If it is
desirable to disable the Auto Off Feature perform the
following steps:
1. Press and hold in the INPUT Push-button until the
MP100 Front Panel Illumination extinguishes and
the Digital Output LO LED is illuminated, then
release the INPUT Push-button. The Auto Off
Feature is now deactivated.
If is desirable to reactivate the Auto Off Feature per-
form step one again and this time the Digital Output
HI LED will be illuminated. The Auto Off Feature is
now reactivated.
Input Selection
Press the INPUT Push-Button to select either the MM
(Moving Magnet) or the MC (Moving Coil) Phono
Cartridge Input.
Phono Cartridge Load Adjustment
In order for a Phono Cartridge (MM or MC) to deliver
sound with the flattest possible frequency response, it
is important for the Phono Cartridge to be connected
to electronics with an Input Impedance (resistance and
capacitance) the same as the Cartridge Load Speci-
factions. The MP100 offers capacitance adjustments
for MM (Moving Magnet Phono Cartridges) and
resistance adjustments for MC (Moving Coil Phono
Cartridges).
Note: Check the information supplied with the Phono
Cartridge or with the Turntable (if it was supplied
with the Phono Cartridge already installed) for the
cartridge's impedance value. If necessary, con-
tact your dealer or the manufacture of the phono
cartridge.
MM LOAD (PF) ADJUSTMENT
When the connected Turntable has a Moving Magnet
Cartridge installed, use the MM LOAD (PF) Control
to select from the six available capacitance values that
is the closest to the Phono Cartridge requirement.
MC LOAD (OHMS) ADJUSTMENT
When the connected Turntable has a Moving Coil
Cartridge installed, use the MC LOAD (OHMS) Con-
trol to select from the six available resistance values
that is the closest to the Phono Cartridge requirement.
Stereo/Mono Mode
The Stereo Mode by default is active for the MM and
MC Input Sources. To change from the Stereo Mode
to Mono Mode, perform the following steps:
Note: The Stereo/Mono Mode affects all the MP100
Outputs (Analog, Digital and USB).
1. Select the desired Phono Input MM or MC.
2. Press the MONO Push-Button on the Front Panel,

the LED above the MONO Push-Button will il-
luminate.
3. Return to the STEREO Mode by pressing the
MONO Push-Button.
Digital Output
The MP100 provides the greatest possible Dynamic
Range when converting the Analog Audio Signal from
the playback of Phonograph Recordings to a Digital
Audio Signal. There are two Digital Output Settings
to accommodate a wide range of Dynamic Range.
For most recordings the DIGITAL OUTPUT HI Set-
ting will produce excellent results. If the CLIP LED
Flashes On, switching to the DIGITAL OUTPUT
LO Setting will produce better results. To switch Off
the DIGITAL OUTPUT Signal Processing, press the
DIGITAL OUTPUT Push-button until the three LEDs
are no longer illuminated.
USB Output Operation and Driver Installation
The MP100 USB Output provides the capability to
record music on your computer from the playback of
Phonograph Recordings through the MP100 Phono
Preamplifier, when the computer is connected to the
rear panel USB connector.
Notes: 1. The MP100 USB Output is for direct connection
to a computer USB single input only.
2. To playback music from an USB Drive, connect
the USB Drive to another USB Port on the com-
puter and select the USB Drive with the Media
Playback Program.
The MP100 USB Output is compatible with PC
Computers using Microsoft®, Windows 7 (SP1), Win-
dows 8.1 and Windows 10. It is also compatible with
Apple® Macintosh® Computers using OS-10.6.8 or
later.
