An extended
Eurocard (220mm x
100mm) with an extension at
the audio transformer end of
the pcb for
Neutric PCB mounting XLR
connectors to be fitted. This
section may be
cut off if not required.
This board offers an easy
method of interfacing
unbalanced stereo audio
equipment for professional use
at low cost yet retaining high
performance.
The MKII board has the
following features:
* electronically balanced
Inputs and Outputs
* provision for mounting of
Lundahl transformers
* 20dB output gain available
* active input stages with
attenuation if required
* built in 240v AC psu
* unbalanced connections on 10
way IDC header (as MKI)
* balanced connections on 16
way header (as MKI) plus XLR's

5690 Keyboard Encoder/Driver
| |
A
PCB containing a 16 key encoding
IC (74C922 with a latch/decoder
(4514)
and Darlington Driver (ULN2803)
for each of the 16 lines. Either
a
keypad or individual switches
can be used as inputs. |
| |
The
output lines have two routes,
one via a resistor network
package for
LED driving, the other direct
for driving lamps, relays etc.
Provision
is also made for inserting
diodes in the output lines if
required. |
| |
The
circuitry can be powered from
+5v to +12v DC as required thus
making it
suitable for interfacing to
other boards and equipment. If a
higher
input voltage is required then
the PCB is laid out to take a
regulator
IC. All connections are via IDC
connectors to allow easy
connection for
servicing. |
