WARNUNG
I
WAARSCHUWING
AVVERTIMENTO
NL
Alle IC’s en vele andere halfgeleiders zijn
gevoelig voor elektrostatische ontladingen
(ESD).
Onzorgvuldig behandelen tijdens reparatie
kan de levensduur drastisch doen
verminderen.
Zorg ervoor dat u tijdens reparatie via een
polsband met weerstand verbonden bent met
hetzelfde potentiaal als de massa van het
apparaat.
Houd componenten en hulpmiddelen ook op
ditzelfde potentiaal.
Tous les IC et beaucoup d’autres semiconducteurs sont sensibles aux décharges
statiques (ESD).
Leur longévité pourrait être considérablement
écourtée par le fait qu’aucune précaution
n’est prise a leur manipulation.
Lors de réparations, s’assurer de bien être
relié au même potentiel que la masse de
l’appareil et enfiler le bracelet serti d’une
résistance de sécurité.
Veiller a ce que les composants ainsi que les
outils que l’on utilise soient également a ce
potentiel.
GB

and that parts which are identical with those specified be used.
NL
Veiligheidsbepalingen vereisen, dat het apparaat in zijn oorspronkelijke
toestand wordt terug gebracht en dat onderdelen, identiek aan de
gespecifieerde worden toegepast.
Alle IC und viele andere Halbleiter sind
empfindlich gegen elektrostatische
Entladungen (ESD).
Unsorgfältige Behandlung bei der Reparatur
kann die Lebensdauer drastisch vermindern.
Sorgen sie dafür, das Sie im Reparaturfall
über ein Pulsarmband mit Widerstand mit
dem Massepotential des Gerätes verbunden
sind.
Halten Sie Bauteile und Hilfsmittel ebenfalls
auf diesem Potential.
D

Fur Reparaturen sind Original-Ersatzteile zu verwenden.
I
Le norme di sicurezza esigono che l’apparecchio venga rimesso nelle
condizioni originali e che siano utilizzati pezzi di ricambiago idetici a quelli
specificati.
Tutti IC e parecchi semi-conduttori sono
sensibili alle scariche statiche (ESD).
La loro longevita potrebbe essere fortemente
ridatta in caso di non osservazione della piu
grande cauzione alla loro manipolazione.
Durante le riparazioni occorre quindi essere
collegato allo stesso potenziale che quello
della massa dell’apparecchio tramite un
braccialetto a resistenza.
Assicurarsi che i componenti e anche gli
utensili con quali si lavora siano anche a
questo potenziale.

Left/Right Clock - LRCK
Pin 12, Input
Function:
The Left/Right clock determines which channel is currently being
input on the serial audio data input,
SDATA. The frequency of the Left/Right clock must be at the input
sample rate. Audio samples in
Left/Right sample pairs will be simultaneously output from the
digital-to-analog converter whereas
Right/Left pairs will exhibit a one sample period difference. The
required relationship between the
Left/Right clock, serial clock and serial data is defi ned by the
Mode Control Byte and the options are de-
tailed in Figures 29-33
Serial Audio Data - SDATA
Pin 13, Input
Function:
Serial audio data is input on this pin. The selection of the Digital
Interface Format is determined by set-
tings of the Mode select as detailed in Figures 29-33. The data is
clocked into SDATA via the serial clock
and the channel is determined by the Left/Right clock. The
required relationship between the Left/Right
clock, serial clock and serial data is defi ned by the Mode Control
Byte and the options are detailed inin
Figures 29-33
Soft Mute - MUTE
Pin 15, Input
Function:
The analog outputs will ramp to a muted state when enabled. The
ramp requires 1152 left/right clock cy-
cles in Single Speed, 2304 cycles in Double Speed and 4608
cycles in Quad Speed mode. The bias volt-
age on the outputs will be retained and MUTEC will go active at
the completion of the ramp period.
The analog outputs will ramp to a normal state when this function
transitions from the enabled to disabled
state. The ramp requires 1152 left/right clock cycles in Single
