[. . . ] You may need to reduce the sampling rate if you are using the Digital Processor Loop, as many external devices will not operate at 96 kHz or 192 kHz. Speaker compenSation (2 ohms, 4 ohms, 5 ohms, 6 ohms, 7 ohms, 8 ohms, >8 ohms): Digital impedance compensation filter allows fine tuning of the top octave to match the speaker impedance. The effect of this filter may not be audible* but it is measurable, and it compensates for the small effect of the digital reconstruction filter that eliminates the 288 kHz sampling frequency of the amplifier. *The exception may be some electrostatic speakers that have very low impedance at high frequency. The lower the HF impedance, the greater the deviation from flat response. polaritY (poSitive, reverSed): Allow compensation for recordings that have reversed polarity. Positive: A positive sine wave at the input remains positive at the output. Reversed: A positive sine wave at the input is negative (inverted) or reversed at the output. IMPORTANT NOTICE For all of the above menu options, a chosen option or level setting will not immediately take effect upon selection. There will be a slight delay or pause before the corresponding action or response is realized. RENAMING A SOURCE INPUT A particular source input can be renamed according to your preference. example: Rename "DIGITAL OPTICAL 1" to "BD PLAYER". 1 Press the front panel "optical 1" button to select "DIGITAL OPTICAL 1" input. Then, press and hold the front panel "optical 1" button until "DIGITAL OPTICAL 1" is shown in the lower section of the VFD and with "D" flashing (Note that "DIGITAL OPTICAL 1" is also shown at upper section of the VFD). 2 Within 5 seconds, rotate the VOLUME control knob clockwise or counterclockwise to select the first character ("B" from the alphabetical list). 3 Press the front panel "loop" button to select the character and at the same time move on to the next character. 4 Complete the renaming process by pressing the front panel "menu" button to save the new source input name. NOTES · Renamingofasourceinputcanonlybedoneusingthefrontpanelbuttons. · Ifnochangeismadewithin5secondsorifthefrontpanelbuttonofthe source input being renamed is pressed, the renaming process will be automatically terminated with any renamed characters made not saved. · Youcanterminatetherenamingprocessbypressinganyotherfront panel buttons (except "loop", "menu" or the current source input being renamed). The renamed characters at the time of terminating the process will be saved. 7 SVENSKA NEDERLANDS DEUTSCH ITALIANO ESPAÑOL FRANÇAIS ENGLISH IDENTIFICATION OF CONTROLS rear panel ENGLISH FRANÇAIS ESPAÑOL ITALIANO DEUTSCH NEDERLANDS SVENSKA 16 17 18 ATTENTION!Please make sure that the M2 is powered OFF or unplugged before making any connections. It is also advisable to power-down or unplug all associated components while making or breaking any signal or AC power connections. [. . . ] · Restart again the M2 by switching ON the rear panel POWER switch (if you have shut down the M2 via the POWER switch) and then pressing the front panel STANDBY button or remote control's [ON] button. · Right output short circuit. · Left and right output short circuit. · Left channel internal error. · Right channel internal error. · Left and right channel internal error. · Error with the internal power supply. · Internal initialization error when powered on. · The M2 is too hot due to insufficient ventilation. No power. · The power cord is disconnected. · POWER switch shut down. · Shut down M2 by turning off the rear panel POWER switch. Ensure that there is adequate space below, above and to the sides of the M2 to allow proper air flow. [. . . ]
