CAUTION : After servicing this appliance and prior to returning to customer, measure the resistance between either primary AC
cord connector pins ( with unit NOT connected to AC mains and its Power switch ON ), and the face or Front Panel of product and
controls and chassis bottom.
Any resistance measurement less than 1 Megohms should cause unit to be repaired or corrected before AC power is applied, and
verified before it is return to the user/customer.

1.1. Digital Output (Coaxial) Check
On the preset menu, set "D.OUT" to "ON".(PMD331/PMD340)
Do waveform observation with the oscilloscope, and confirm
the digital output level of JT01 to be 0.5Vp-p, square wave
within ±20% .
1.2. Balanced Output Adjustment (PMD331/PMD340)
1kHz, 0 dB are played back by using TEST disc.
Turn RB01 on the rear panel, and adjust the output of JB53
(Balanced Out L-CH).
Turn RB02 on the rear panel, and adjust the output of JB54
(Balanced Out R-CH).
Adjust each output level to 16 dBu, within ±0.5dB.
1.3. Service Mode
1) With power off, simultaneously press the PLAY/PAUSE,
MODE and TIME buttons, and at the same time, press the
power button. At this time the LCD shows the model name
and firmware version.
2) Next, press CUE button.
3) At this time the LCD shows " Test : Version ". (TEST MODE
select menu)
4) The NEXT and PREVIOUS buttons change the TEST
MODE(refer to the chart below). The PLAY button selects it.
5) Pressing the CUE button returns to the TEST MODE select
menu.
6) Press the STOP button to exit the service mode.

Notes)
* PCMD is a MSB first, two's complement output.
* GTOP is used to monitor the frame sync protection status. (High: sync protection window released.)
* XUGF is the frame sync obtained from the EFM signal, and is negative pulse. It is the signal before sync protection.
* XPCK is the inverse of the EFM PLL clock. The PLL is designed so that the falling edge and the EFM signal
Atransition point coincide.
* The GFS signal goes high when the frame sync and the insertion protection timing match.
* RFCK is derived from the crystal accuracy, and has a cycle of 136us. (during normal speed)
* C2PO represents the data error status.
* XROF is generated when the 32K RAM exceeds the +-28F jitter margin.

PIN NAMENUMBERFUNCTION
Input Interface Pins
LRCIN1Sample Rate Clock Input. Controls the update rate (fs).
DIN2Serial Data Input. MSB first, right justified format contains a frame of 16-bit or 20-bit data.
BCKIN3Bit Clock Input. Clocks in the data present on DIN input.
Mode Controls and Clock Signals
CLKO4Buffered Output of Oscillator. Equivalent to fs.
XTI5Oscillator Input (External Clock Input). For an internal clock, tie XTI to one side of the crystal oscillator. For an external clock,
tie XTI to the output of the chosen external clock.
XTO6Oscillator Output. When using the internal clock, tie to the opposite side (from pin 5) of the crystal oscillator. When using an
external clock, leave XTO open.
CKSL23System Clock Select. For 384fs, tie CKSL “High”. For 256fs, tie CKSL “Low”.
MODE24Operation Mode Select. For serial mode, tie MODE “High”. For parallel mode, tie MODE “Low”.
MUTE25Mute Control. To disable soft mute, tie MUTE “High”. To enable soft mute, tie MUTE “Low”.
MD/DM126Mode Control for Data/De-emphasis. See “Mode Control Functions” on page 11.
MC/DM227Mode Control for BCKIN/De-emphasis. See “Mode Control Functions” on page 11.
ML/DSD28Mode Control for WDCK/Double speed dubbing. See “Mode Control Functions” on page 11.
