5 Basic operation of the electronics
This chapter describes someof the key circuits of the PPE2470. The
completecircuit drawingscan be found on page 18 to 44.
5.1 The input / output board
The input / output board contains the electronics for the input
amplifiers, the bypass
relays, the output amplifiers, the MIDI and
the SAnetconnections.
The input amplifier is a straightforward opampdifferential
amplifier.
The amplifier provides for a 3 dB gain. Common
moderejection can be
trimmedwith TR2for low frequencies and with TRl for high
frequencies. See
page
52 for the exact adjustment
procedure. The
value of R4 is three times higher than R5 to obtain the same
input
impedanceat the + and - inputs (24k0 each leg).
o{í $ttr
Fig 4 Input amplifier
Both inputs and outputs are equiped
with reiays to provide full
bypass in case the power of the equaliser is turned off.
The outputs are electronically balancedand have
a DC servo
feedback. This feedback
provides for a Iow output offset.
The outputs are cross-coupled so that a shortcircuit of one output
results in a 6 dB extra gain on the other (transformer simulation).
Output symmetrycan be adjusted with TRS
and TR6. See page 52 for
the adjustment procedure.
The output board also contains the digital interfaces.
A SN75176RS422
driver provides the SAnet interface.
MIDI,
is only buffered and the controller is located on the processor
board

5.2 The boost / cut board
The boost / cut board contains the electronics to supply the filters
with the right amount
of signal and to add the filter output to the
original signal.
Each
of the two channels has its ownboost / cut board and figure 6
shows
the basic set up.
The input level is controlled by DCl and extra gain can be addedÍn
the feedback
network around
R13
and R14. The digital code at the
digital input of the DAC
determines
the attenuation of the circuit.
This level in dB can be calculated with the formula:
A=20*Iog n
4096
where n is the decimal value of the bit code. when
extra gain is
used, add 10 or 20 dB.
since the Ínternal resistance of the DA
converter influences the
overall gain of the circuit, R13, R14and R15
should be matched
to
the DA
converter. Page
22 contains a table where
the exact values
canbe found.
TheDAC
resistance
can
be measured
between
pins 1 and20 after
has
beenremoved
fromits socket.A condition is that you have
supply
the DAC
with a voltage
of 1.2V between
pins 3 (Gnd)
and
18 (vdd).

FiS. 6 Boost / cut board set uP
Next the signal is fed to four DA
converters which provide the cut
signal for the state variable filters. In figure 6 only one (DC4)
is
shown
for the cut signal of filter 1. This circuit can provide a
gain factor of -0.89.
After inverting the signal with IC1-b, another four DAconverters
feed the signal for boost purposes
to the filters. The boost circuit
for filter 1 is shown
(DC8)
and this circuit can provide a gain
factor of 8.44,
Here again, aII the feedback
resistors have to be matched
to the
DAC.
The values can be found in the tables at page
24. The DAC
resistance can be measuredbetween
pins 1 and 16 after the DAC
has
been removed
from its socket. A power
supply is not necessary.
The original signal is added
with the filter outputs at the input of
ICZ-a. The polarity of the output signal of each
of the filters
determines
whether the signal is going to be boosted
or cut at a
certain frequency. The frequency is determined
by the filter
settings at the filter board
The output level is controlled by DCZ.

5.4 The
clip and
level detectionboard
Themain
function of the clip andlevel detectionboard
(see
schematics
at page
33) is to interface analoglevels to the
microprocessor.
There
are two types of interfaces, one
for Ievel
detection andone
for clip detection.
For the level detection, four analogue
signals (both the inputs and
both the outputs) are precision rectified (Fig 8) and
fed to an
analoguemultiplexer. After the multiplexer, eachof the DC
signals
is convertedin a digital code.

converteris built aroundIC1, IC2andIC3. After the
multiplexer the signal is passed
to a buffer andcomparator IC3

level dependson the digital code

D is the analog value of the digital code (00000000

For the cIÍp detection, all possible places where
an overload can
occur are sensed
and fed to comparators.These
are:
The two inputs of the equaliser (an overload can occur when
10 or 20 dB extra gain is used).
- The four boost outputs of each channel (each filter can
provide 19.5 dB of gain).

5.7 Thefront control board
The
front control boardcontains
the drive electronics for the
displays on the front boardand
the circuitry to readthe position
of the switches.
All information
for the displays is sent serially to the front
board. Eachframe
contains
the informationfor onecolumn
(32 bits).
Eachtime data is written to a certain columnof leds or displays, a
read
anda write cycle is performed.
In the read
cycle, the "video int" level is lowand
the display data
is stored by the processor
into RAllIC9. The
processor
adressbuss
is passed
to the RAIIthrough
ICl andIC2. The
data contains32 bits
that are divided over 8 nibbles. The
data is stored into IC9
through
IC10-A.
In the write cycle, "video int" is high anddisplay control is taken
over completelyby the control circuit. TheRAl,{nibbles are
subsequently
loadedinto IC11
andserially transmittedto the front.
The
endof the cycle is detectedby ICS.
The
readout
circuit for the switches
comprehenses
IC12, IC13 and
IC14.
Thekeybuf
signals are normallyhigh. To reada row of
switches,
oneof the keybuf
signals is madelow by the processor.
The
output of IC13
goes
low
andthe keycot
byte is transferred to
the data bus.
5.8 Themother
board
0n the mother
boardall interconnections
betweenthe various PCB's
are made.
It also containsthe decodinglogic for variouscontrol andchip
enable
signals.
5.9 The
power
supplyboard
The
power
supply
(page
43 and 44) is a straightforward regulated
supplywith 78 and79 series regulators.
The
5 volt supply
(mainly
for the digital circuitry) is extended
with a power
transistor to provide for a higher
current capability.
Its output is filtered to eliminate
processor
noise
out of the
supply
andmainsnoÍse
out of the processor
circuit.

The
processor
circuit (see
page

and
the MIDI
controller.
The
processor
hasthree different kinds of on board memory.
IC4 is
an EPROI'Iwhich
contains
the software for starting the processor,
testing the other memories
anddownloading
the system software.
IC3, a Flash
EPRO}I,
contains
the systemsoftware andcanbe
programmed
through
SAnetwithout removingit.
ICSis a RALlwhich
contains
program
variables, e.g. the equaliser
control settings. This IC is provided with battery backup
to save
the settings when
the mains
power
is switched off. The battery has
a life time of approx. 10 years.
IC7 and IC8 are protection IC's to save
is switched on and off.
IC6 is the MIDI controller which is the
MIDI and the processor.

5.6 Thefront board
The
front board
(seepage

the user interfaces:

Boththe readout
of the buttonsand the display drive are
multiplexed.
The
buttonsare scannedin the following víay:
AII keyrow
signals are normallyhigh. Keycol0 to 7 are normally

a rorf, of switches,
its keyrowinput is made'Iow'by the processor.

issue: update I
Resistor and capacitor values for PPE-2410band 1 frequency circuit
using SA1010or AD7524JN. In general, PPE'swith an lD-code > 121
use E12-range
capacitor values. However,values with an "t" are E24.
Resistor values are in ohms,capacitor values are in picofarads.
