tridge Loading values, refer to figure 61. The change-

able load value is indicated on the Front Panel Display 

by an Equal Symbol (=) between the Loading Type 

and Value. To change the current Resistance Load 

Value, rotate the Front Panel LOAD Control, refer to 

figures 61 and 63.

To change the Capacitance Load Value first momen-

tarily press the LOAD Control and the Equal Symbol 

(=) will now appear between the Capacitance Loading 

Type and Value. Refer to figure 64.

To change the current Capacitance Load Value rotate 

the Front Panel LOAD Control, refer to figures 64   

and 65.

Trim Functions

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-

Remote Control. Refer to figures 60, 62 and 66.

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 

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-

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      (Power On) 

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.

Note: For an explanation of the Remote Control 

Push-button functions, refer to page 12.
