    INTRODUCTION Mytek 8X192 ADDA is an 8 channel Analog to Digital and an 8 channel Digital to Analog converter maticoulsly designed to provide the highest quality signal path. No compromises have been made to sound quality, and we feel that this is the best sounding Mytek converter to date.
  • Page 6: Signal Flow

    SIGNAL FLOW The 8X192 ADDA has two independent signal paths within the unit. They offer independent signal paths but must operate at the same clock source and sampling frequency. It's recommended that as much as possible the unit should be clocked from its internal CX 797 clock generator.

    AND OTHER INTERNAL ADJUSTMENTS Analog input/output alingment The 8X192 ADDA analog input/output sensitivity comes as factory default fixed at -15dBFs corresponding to +4dB (OVU=1.228VRMS measured between hot and cold). This gain is optimal for most situations and unless another level "is necessary for systemic reasons, we recommend leaving the gain at the default setting.

    SETTING CLOCKING AND SIGNAL SOURCES NORMAL OPERATION. AD AND DA ON INTERNAL CLOCK. AD FEEDING THE RECORDER, DA MONITORING RECORDER LED ON LED OFF In this mode both the AD and DA run on the internal clock. This mode provides the lowest jitter and most sonically robust performance.
  • Page 13 NORMAL OPERATION. AD AND DA ON EXTERNAL WORDCLOCK. AD FEEDING THE RECORDER, DA MONITORING RECORDER LED ON LED OFF In this mode both the AD and DA run on an external clock. Holding the "Ext. Clock Source" button selects this mode. Although this mode does not provide the lowest jitter performance it might be desirable for systemic reasons.
  • Page 14 NORMAL OPERATION. AD AND DA ON EXTERNAL CLOCK OTHER THAN WCK. AD FEEDING THE RECORDER, DA MONITORING RECORDER LED ON LED OFF In this mode both the AD and DA run on an external clock. Although this mode does not provides the lowest jitter performance it might be desirable for systemic reasons.
  • Page 15 FORMAT CONVERSION OPERATION. ADC IS OFF, DIGITAL IN TO DIGITAL OUT, DA MONITORING DIGITAL IN. LED ON LED OFF In this mode the 8X192 unit can be used for format conversion between all installed digital interfaces. Once a digital input is selected for "SOURCE TO DIGITAL", the "SAMPLE RATE" switch is disabled and EXT.CLOCK SOURCE and SOURCE TO ANALOG OUT automatically set to selected digital input.
