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

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. |
