Technics
SA-DX930 Receiver
Affordable Digital Surround - for the mainstream consumer
By Jim Bray
Technics has long
been one of the leading names in consumer home audio components (among
other things), so it isn't surprising that it would have a series of competitive
entries into the audio/video receiver marketplace.
The SA-DX930 is in
Technic's "higher end" of affordably priced ($400US) units and offers
all the major features the average consumer will need for a relatively
modest, yet relatively state-of-the-art home theater. For example, it
gives you both Dolby Digital AC-3 and DTS digital audio decoding, and
a good sounding amplifier that cranks out 100 clean watts into each of
the five channels - and that's the bottom line for a reasonable home theater
receiver today.
Like the Sony
STR-DE835 A/V Receiver reviewed elsewhere in TechnoFILE, this Technics
is a "mainstream" receiver, which means it's positioned in the lower to
middle end of the market - where most people shop. Like the Sony, this
is an affordable unit; unlike the Sony, it isn't chock full of digital
toys and isn't as flexible. It's also cheaper, though, so that may make
up for some of the differences.
The Ins and Outs
The receiver comes
with conventional RCA inputs for Phono (a nice touch one doesn't always
see nowadays), CD, Tape, DVD, VCR, and TV/DSS. It also has two optical
inputs - designated for a CD player and a Digital Satellite System - and
a coaxial digital input for a DVD player.
This arrangement of
digital inputs struck us as a bit strange, since our DSS receiver has
no digital output (though it's also a couple of years old) and we like
to use the optical digital audio output from our reference DVD player.
This meant we had to hook the DVD player into the TV/DSS inputs and vice
versa to get our favorite configuration. Not a big deal, but a surprising
oversight.
We were also surprised
to find very small and compartively fragile, "clip-type" speaker terminals
instead of the much preferred binding posts. This made it difficult to
hook in our "banana plug-equipped" heavy gauge speaker cable, though it
won't be a drawback for people who use the more common and thinner gauge
speaker wire. Still, it struck us as another oversight in what's generally
a good unit.
The layout of the
handsome front panel is straightforward, from the power button to the
"sound mode selector" and "Sound Field Control" selector (that lets you
choose from a variety of stereo, surround, or digitally synthesized listening
environments like club or concert hall), to the rotary input selector
and the big volume control. There are also tone/balance controls, tuning
and preset/memory buttons for the tuner section, and a large display section
that reads out about as much information as you could want. Some of the
display sections are pretty small and hard to read from across the room,
but this is a common problem with such components.
There's also a "Help/reset"
button which is a nice way to bail yourself out of any programming/setting
mistakes you make while getting to know the system.
Using the SA-DX930
is pretty straightforward once you have everything hooked in (though the
layout of the input panel on the back leaves something to be desired)
and we found listening to it to be a very pleasurable experience. As with
the last Technics receiver we tested, this unit produced very good sound
quality that belied its low price.
Still, it's inevitable
that corners be cut in such an affordable unit, and one big corner Technics
trimmed was the remote control, which (to be bluntly honest) was a real
disappointment. It's a "universal" remote, so it controls various components
from various manufacturers, but it's too small, poorly designed and laid
out, and we had problems working it. We'd prefer to have seen Technics
add a few bucks to the admission price and put a real remote here.
Still, this problem
isn't unique to Technics, either, though this particular remote is one
of the poorer examples that we've seen. We found ourselves getting up
from our easy chair and controlling most functions from the front panel
- and using the other components' remotes for their operation instead
of trying to muddle through with this Technics. This made the remote rather
superfluous.
The owner's manual
does a decent job of walking you through most of the hookups and operations
and, like most of the complex audio/video receivers these days, you'll
probably want to spend some time here when you unpack the unit. It'll
help you get comfortable with the features and how to access them.
On the whole, we were
disappointed with some of the "fuzzily thought out" features we've mentioned
above, but feel that if you can live with them, this Technics receiver
can be a good value for the dollars spent. It offers true digital home
theater surround sound for a budget price, and gives audio quality above
and beyond its modest cost.
So while we'd encourage
readers to spend a couple of hundred dollars more and get a higher end
audio/video receiver with fewer compromises, people for whose budgets
this Technics is truly intended may find this product well worth a look
and, even better, a good listen.
