ENGLISH OPERATION USING A MASTER CLOCK GENERATOR WHEN PLAYING DISCS The master clock generator In digital devices such as CD players or super audio CDs, there is a process that samples or restores the analog signal. In order to conduct this process, a clock signal (sampling frequency) is used. A master clock generator is an oscillation device that makes this clock signal. The clock signal output by the crystal oscillator built into this unit is extremely accurate, enabling you to fully enjoy high quality sound playback. However, you can also perform playback using the clock signal output from an external master clock generator, to enjoy the difference in the sound that the master clock generator can provide. In recent years, research has found that the difference in clock signals causes differences in tone quality. In response to this finding, many companies have released master clock generators. Generally speaking, the more precise the clock signal time base is, the closer it is to the natural time base of the sound, thus enabling the reproduction of higher fidelity sound. Therefore many master clock generators insist that they are capable of outputting a highly precise clock signal. Anyway, the different clock seems give differences sound tone. This unit offers the possibility of enjoying the change. The frequency of the clock signal that can be input into this unit is 44.1, 88.2, or 176.4kHz. Use a master clock generator that is capable of outputting these signals. 7 Using a master clock generator for playback Should you elect to use an outboard master clock generator, be sure to select one that has an extremely accurate clock to avoid degrading the sonic performance of this unit. OPEN/ CLOSE DISPLAY OFF 44.1KHz 88.2KHz 176.4KHz LOCK EXT.CLOCK POWER ON/OFF INV.PHASE SOUND MODE PLAY STOP PAUSE t, u y q, r q Switch off the power supply. w Connect the EXT. CLOCK INPUT connector on the rear of this unit to the output connector of the master clock generator using a commercially available BNC terminal coaxial cable. (See page 12) e Switch on the power of the master clock generator, and check the clock frequency to set. For details on this operation, please refer to the instruction manual that came with your master clock generator. r Press the POWER switch on this unit to switch on the power supply. t When the unit's LCD display is on, press the EXT. CLOCK button on the front of the unit. y Each time the EXT. CLOCK button is pressed, the clock frequency indicator lights in the window, in the order shown below. OFF (Internal clock operates) 44.1 kHz 88.2 kHz 22 176.4 kHz u Press the EXT. CLOCK button to match the frequency with the clock frequency set in the master clock generator, and when the LOCK indicator switches on, the settings are complete. You will be able to hear the changes in sound quality by changing the clock signal. Set the frequency to your own personal tastes. Caution: • Switch between the master clock generator and the internal clock when playback is stopped to prevent excessive sound occurrence from the speaker. • Sound will be muted when the LOCK indicator blinks. Check the settings of your master clock generator, the connections etc. During this time, the DIGITAL OUTPUT signal will not be muted. • The information after this operation is stored by the last memory function even after the power is switched OFF.
