GB WARNING
All ICs and many other semiconductors are susceptible to
electrostatic discharges (ESD). Careless handling during
repair can reduce life drastically.
When repairing, make sure that you are connected with the
same potential as the mass of the set via a wristband with
resistance. Keep components and tools at this potential.
F ATTENTION
Tous les IC et beaucoup d´autres semi-conducteurs sont
sensibles aux décharges statiques (ESD). Leur longévite
pourrait être considérablement écourtée par le fait qu´aucune
précaution nést prise à leur manipulation.
Lors de réparations, s´assurer de bien être relié au même
potentiel que la masse de l´appareil et enfileer le bracelet
serti d´une résistance de sécurité.
Veiller à ce que les composants ainsi que les outils que l´on
utilise soient également à ce potentiel.

Alle ICs und viele andere Halbleiter sind empfindlich
gegenüber elektrostatischen Entladungen (ESD).
Unsorgfältige Behandlung im Reparaturfall kann die
Lebensdauer drastisch reduzieren.
Sorgen Sie dafür, daß sie im Reparaturfall über ein Pulsarmband mit Widerstand mit dem Massepotential des
Gerätes verbunden sind.
Halten Sie Bauteile und Hilfsmittel ebenfalls auf diesem
Potential.

NL WAARSCHUWING
Alle IC´s en vele andere halfgeleiders zijn gevoelig voor
electrostatische ontladingen (ESD).
Onzorgvuldig behandelen tijdens reparatie kan de levensduur
drastisch doen vermindern. 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.
I
Tutti IC e parecchi semi-conduttori sono sensibili alle scariche
statiche (ESD).
La loro longevità potrebbe essere fortemente ridatta in caso di
non osservazione della più grande cauzione alla loro
manipolazione. Durante le riparationi occorre quindi essere
collegato allo stesso potenziale che quello della massa
delápparecchio tramite un braccialetto a resistenza.
Assicurarsi che i componenti e anche gli utensili con quali si
lavora siano anche a questo potenziale.

- The intention of this description is to explain the most important performance measurements for DPL (Dolby Pro-Logic)
sets for service.
- Test instruments (recommended) :
- Dolby Prologic test CD 4822 395 10216
- AC mv meters (4x) L, C, R, S
- Oscilloscope (double beam)
- Distortion meter
- CD player.
WARNING:Be sure that the ground connection (-) of each instrument is not connecteded with
the safety earth ⊥ connection. To avoid damage to output amplifiers (balance type)
Use only cinch (input) ground connection
STARTING CONDITION :
-Replace the loudspeakers for all four output amplifiers with loud resistors according the output impedance for each
amplifier (or use 8 Ω as standard loudresistor).
-Set volume to min. position
-Set Bass + Treble at 0 db .
-Select Surround <Prologic> .
-Select “LARGE” size for Center channel.
-Set time delay in Surround channel at 20 msec.
-Dolby Prologic test CD in CD player.
SERVICE TEST DESCRIPTION
Test 1 : Output and balance setting for all four channels
Select track 2 :
Adjust L, C, R and S for ≈ 1W output on the loudresistor with master volume. Adjust with L/R balance and
Centre/Surround “TRIM” all four channels to equal level (equal meter readings)
Note: 1Watt output corresponds with 2.83V across 8 Ω
P = U≤/R → U = √ P x R = √ 1x 8 = 2,83V
Test 2 :Frequency response for Left and Right channel
Requirement : -3 dB points at ≤ 50 Hz and ≥ 15 kHz
Select track 3:
measure (and note) the overall gain of Left channel across the load resistor.
Select track 4:
measure (and note) the overall gain on Right channel across the load resistor.
Test 5 :Modified Dolby B type NR decoding freq. response of the Surround channel
Requirement : Roll off behaviour at ± 5 kHz related to 100 Hz. In this case use 100 Hz as 0 dB reference gain.
Select track 14:
measure (and note) the overall gain of Surround channel across the load resistor.
Note : The output level on track 14 = -35 dB below the 1W output reference of the Surround channel.
Test 6 :Total harmonic distortion measurements for Left, Center, Right, Surround channels for 1 Watt output
Note : If necessary use a special CD test filter 20 Hz ... 20 kHz between the output channel and the distortion meter
to prevent spurrious products out of audio waves (> 20 kHz) from to the CD player in test.
Select track 3 :
Measure distortion at 1 kHz across the Left channel.
Output load resistor : requirement THD < 0,3 %
Select track 4 :

1- Center size “LARGE” requirements : -3 dB at ≤ 50 Hz and ≥ 15 kHz (same as L/R requirements)
2- Center size “SMALL” requirements : -3 dB point at ± 100 Hz and ≥ 15 kHz (the difference is the
roll-off behaviour of the bass frequencies).
Select track 5 :
measure (and note) the overall gain of Center channel across the load resistor in “LARGE” size (only in sets with
this option) and repeat this measurement in “SMALL” size.
Test 4 :Frequency response for Surround channel
Surround requirements : -3 dB point at ≤ 100 Hz and ± 7 kHz (6 kHz ... 8 kHz)

Test 24 : Time delay control in Surround channel
-Principle description encoded burst signal spots (see fig. 1)
1- Tone burst 1 kHz during 1 msec with interval time at 20 msec are given at the same time to the Lt; Rt inputs.
(in phase 0∞)
2- The next tone burst is given at the same time to the Lt Rt input, but in reverse phase to the R
These 2 tone bursts are repeated continuously during 2 minutes.
-Principle description decoded signal spots in Center/Surround channel
- In case of 20 msec time delay mode the results are shown in fig. 1 in Center and Surround channel.
The center spots in Center channel can be used as ìMarkerî spots (trigger signal) → repeated every 40 msec.
The delayed surround spots occur at the same time as the center spots (markers)
- When time delay mode is changed to 15 msec the delayed surround spots move to the left with respect to the centre
mark spots.
- When time delay mode is changed to 25 msec or 30 msec the delayed surround spots move to the right with respect
to the center spots.
- In case of no time delay ! (faulty condition) the surround spots fall just between 2 center markers spots (20 msec)
-How to check with a double beam scope
WARNING: Be sure that the ground connection (-) of each instrument is not connecteded with the safety
earth ⊥ connection. To avoid damage to output amplifiers (balance type) Use only cinch (input)
ground connection
- Select Pro Logic size “LARGE” or “SMALL” (phantom in case of no Center output.)
- Select 20 msec time delay in Surround channel.
- Adjust scope at 5 msec/division and trigger at A input
- Connect input A to Center channel (or L or R in case of phantom mode)
- Connect input B to Surround channel
- Adjust trigger level and the X position to set pulse A in the middle of the scope . see fig.2 (if L or R used in
phantom mode choose the largest (amplitude) pulse. see fig 3
Select track 24:

Change time delay to 15 msec (only in versions with variable delay).
he surround pulse in channel B moves to the left with respect to side from center marker (channel A) position.
Change time delay to 25 or 30 msec (versions with variable delay).
The surround pulse in channel B moves to the right with respect to center marker (channel A) position.
Time delay with track 6
Alternative methode :
The functional operation of the time delay can be made visible with a lisajous figure, with an single beam scope.
Connect X-direction on Surround output
Connect Y-direction on Left or Right output/input.
Note : be careful and use only 1 ground connected to scope.
Select track 6 (surround test) :
Make the lisajous figure visible on the scope (amplitude adjust) see fig. 4
