POBUSHER'S LETTER
On taking risks
and picking winners
This month we begin presentation of a project which represents our
biggest R&D effort so far - our new 16-Channel Mixer. We believe
that this project would represent a large investment for any commercial organisation but for us it has been very large indeed. We're very
proud of it. From start to finish, it has been more than a year in
coming.
Such a large project is not without a considerable element of risk.
There is firstly the risk that a fair number of readers may not be interested or impressed, or may even be turned off completely, because
it doesn't contain some feature or other. Second, there is always the
risk that the unit may have some bugs which will cause us some pain in
the future. Still, these are the risks in publishing a technical magazine.
These are risks that we gladly take on as we are here to push the
technology forward.
In fact, we take these risks every month to some degree. In the
December issue for example, we published the Digital Voice Board using the new Texas Instruments TMS3477 chip. We did so because we
thought it contained some very interesting new technology and
therefore merited space in SILICON CHIP. We didn't think it would be
popular with many readers. Well, we were completely wrong. Both we
and the stockists for Texas chips were overwhelmed with the interest
from readers. All Australian stocks of the TMS3477 chips were exhausted within days of the magazine going on sale. More than that,
large back orders were placed on overseas sources.
The expressions of interest, and orders, came from everywhere from technical people in security firms, PA and audio manufacturers,
government railways and other instrumentalities, radio stations, and
even the NSW Conservatorium of Music. With the benefit of 20:20
hindsight, it would have been nice to have cornered the market in
TMS3477 chips.
So sometimes you can be wrong and other times you can be right.
Most of the time, luckily, we are right.
This month we take the risks again, in particular with the mixer. We
have spent a large amount of time and money designing and presenting
it. However, while we think that many readers will be interested to
read about its up-to-the-minute design, we don't think it will be built in
very large numbers - perhaps hundreds at the most. But then, we
could be wrong again, couldn't we?
