How to Operate the MP1100

Power On and Off
The Red LED above the STANDBY/ON Push-button
lights to indicate the MP1100 is in Standby mode.
To switch ON the MP1100, press the STANDBY/ON
Push-button on the Front Panel or the
Push-button on the Remote Control. The MP1100 will
then go through a brief startup initialization with the
Front Panel Information Display indicating "MP1100
TUBE WARMUP" for 15 seconds, with the Tubes
glowing an amber color. The Front Panel Information
Display will then indicate the last used source and
its settings, with the Tubes now glow a green color.
Refer to figures 60, 61, 62 and 66. To switch OFF the
MP1100 press the STANDBY/ON Push-button on
the Front Panel or the Push-button on the Remote
Control.

Load Control
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 Specifac-
tions. The MP1100 offers capacitance and resistance
adjustments for MM (Moving Magnet Phono Car-
tridges) and 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
RIAA
cartridge's impedance value. If necessary, con-
tact your dealer or the manufacture of the phono
cartridge.
The LOAD Control is for changing the Capacitance
and/or Resistance Phono Cartridge Loading Values
from the default settings. The bottom line of Front
Panel Information Display indicates the current Ca-

pacitance (50pF) and Resistance (47K) Phono Car-

The MP1100 has twelve different Trim Selections with
Adjustments. The Trim Selections include Cartridge
Profile (Phono Inputs), Resistance (Phono Inputs),
Capacitance (Phono Inputs), Gain (Phono Inputs),
Equalizer (Phono Inputs), Rumble Filter (Phono In-
puts), Scratch Filter (Phono Inputs), Digital Out Level,
Sample Rate, Mono/Stereo Mode, Meter Lights and
Display Brightness. The Trim Settings are stored in
memory independently for each Input Source Select-
