Roland RCS-848
- Positive Features: Extremely flexible and sophisticated system
consists of a HUB with a basic 8-unit control panel (8 student workstations
and 1 teacher station). Up to FIVE additional control panels (RCS-8EXP
expansion kits) can be networked to the HUB for a total of 48 individual
student workstation controls. Individual keyboards are equipped with
a small mixer -- student interface unit (SI Unit) -- into which
are plugged the sound output of the keyboard along with the student's
headphones. The SI Units are then connected to the RCS-848
via network cables (CAT-5) which are plugged into the back of the
RCS-848. Students control
their individual volumes by adjusting the volume control on their
keyboards. There are no volume controls on the SI Units.
Roland RCS-848 - Negative Features: None to speak of. One
minor problem is the lack of an audio input into the student headphone
box. However, most of Roland's keyboards have auxiliary inputs so
that is not a serious problem unless you're planning to use the RCS-848
with older keyboards which may not have inputs. We retrofitted the
SI-Units with auxiliary inputs to handle General MIDI sound
modules and that has worked well.
The Roland system is no doubt the most flexible Class Piano Lab and
is definitely THE EASIEST TO USE. If there are serious techno-phobes
in your school who are intimidated by pressing buttons on scary black
boxes, then this is the system for you -- ANYONE can use this system
FIRST TIME without having to read any technical manuals.
Korg GEC3 - Positive
Features: Sophisticated and state of the art system with computer
interface (IMB-PC only, but Macintosh version promised in the future)
and software which reproduces the touch-screen on the computer (perhaps
easier to manipulate with a mouse). Instructor record keeping software
(grades, attendance, etc.) is described, although we have not seen
this demonstrated. Two GEC3's can be interfaced together for
a total of 32 individual workstations.
Korg sells the individual student interface (headphone) boxes separately
and you can design a lab with as few and as many stations as you want.
The Korg student headphone boxes are sturdy (metal, not plastic)
and have auxiliary audio and microphone inputs.
Korg GEC3 - Negative Features: We have not found any negative
features to speak of in the system itself. Korg has committed to an
unusual headphone design from Koss which uses a specialized
mini-XLR jack. Consequently, "regular" stereo headphones
can not be used. The Koss headphones are not heavy duty and wear out
quickly. Although inexpensive to replace ($5.00), the replacement
time for us was 2-3 months (our experience as opposed to the 3-4 weeks
as advertised). Korg has recently made available an ADAPTER for their
system which will allow the use of "regular" headphones
($25.00 each).
Here's a "biggie" negative. Korg will not warranty their
system with any other pianos except Korg pianos. This is really stupid
because the only physical connection between the student headphone
boxes and the individual pianos is AUDIO and this is just a simple
stereo patch cable (DUH!). Nevertheless, this is the situation and
if you decide to go with a Korg class piano lab system, be prepared
to purchase new Korg pianos as well ($$$) unless you're willing to
go-it-alone on the warranty.
Other manufacturers (Roland and Yamaha) have recently gone with a
flexible modular design. Consequently, labs can be configured in groups
of 8, which means that you could have any configuration: 8, 16, 24,
32, or 48. This is especially good news for schools needing small
labs (4-8) since you can install a lab at a VERY reasonable cost.
Also, it is possible to design a single lab with up to 48 workstations
-- the equivalent class piano hell!
Nevertheless, Korg has stayed with their old design which means that
you are locked into a system which accomodates either 16 or 32 workstations.
Of course, you could use the basic controller in a small lab, say
of 4 - 8 workstations, but you would still have to purchase the complete
controller which has 16 workstation hookups. And it's not cheap!!
The basic controller with related paraphenalia including cables, student
interface boxes, and headphones for 8 workstations lists for $4295.00.
A similar Roland System lists for $3495.00.
Yamaha MLC 100
- Positive Features: The MLC 100 is relatively inexpensive (under
$3000.00), easy to learn how to use, yet elegant and sophisticated.
Yamaha MLC 100 - Negative Features: The Yamaha headphone boxes
do not have any auxiliary audio inputs. Consequently, there is no
place to connect an auxiliary sound (synth) module to the individual
student headphone box for those who want to do this. This is not a
huge problem if you don't mind using TWO sets of headphones on each
student workstation (one for the piano and one for the synth module).
But, this means you now have 32 sets of headphones to look after instead
of 16 (ARGGGHH!!). Most professional model digital pianos (including
some, but not all, of the Yamaha Clavinova series) have auxiliary
audio inputs in the back along with MIDI and auxiliary audio outputs.
In addition, many digital pianos have a BUILT IN General MIDI sound
bank. But our experience has shown that most elementary schools opt
for inexpensive student pianos and these do not have auxiliary audio
inputs or General MIDI sound banks. There are only two solutions to
this problem: (1) use an add-on audio line mixer (Radio
Shack, $89.95); (2) have the student headphone boxes RETROFITTED
with an auxiliary input. We have not had any experience retrofitting
a Yamaha headphone box, but we assume that it would be similar in
cost to retrofitting a Roland box (see above under Roland). Don't
even think about using "Y-adaptors"
to get around this problem -- it just won't work. You end up changing
the impedance of the the headphones and introducing and unbearable
HUM into the audio system. A line-mixer or a retrofit is the only
solution.
We have not found any negative features to speak of in the system
itself. However, (similar to Korg, see above) Yamaha has a corporate
sales philosophy which prohibits ALL authorized Yamaha dealers from
selling their class piano systems -- that is, all dealers which sell
Yamaha products (such as guitars, drums, etc.) are not allowed to
sell the MLC100 class piano system. Although Korg has only
ONE authorized dealer nationwide, Yamaha has only one designated dealer
REGIONALLY. But, you still have the problem of not being able to get
competitive bids. When the system is available from ONLY ONE dealer,
why should they give you a break on the price? Getting timely repairs
may also be a problem when there is only one regional dealer.
Kurzweil KCL
- Positive Features: The KCL Class Piano Lab is potentially
a promising new design. It is AFFORDABLE, easy to install, and easy
to use. It would be ideal for schools that are looking for a new,
state-of-the-art class piano lab but who are definitely budget minded.
However, with the ongoing state of confusion of the Kurzweil company
and the unknown availability of its products, it would be foolish
at this time to consider a Kurzweil system. We certainly hope this
situation changes in the new future and we will keep you informed
on this website. CHECK BACK OFTEN!
Kurzweil KCL - Negative Features: Unknown availability and
support of its products.
Kawai KML-SG - This
product may no longer be available.
Kawai KML-SG - Negative Features: The only negative feature
of the Kawai system is that it is an old design. At a time when all
other manufacturers have gone to ETHERNET cables for connecting audio,
the Kawai system is still using MIDI cables. Don't be confused here
about the MIDI cables. About 15 years ago, ALL the class piano
lab systems were using MIDI cables (which were SHIELDED, cheap, and
readily available) to connect the audio from the individual student
headphone boxes to the teacher control unit. There is absolutely NOTHING
wrong with this design and it works great (it's quiet). However, ETHERNET
is much easier to install, especially where unusual lengths are concerned
and since ethernet cable has become so prevalent in computer installations
in recent years, it has become the audio connection of choice for
new class piano lab systems.
One way to look at the Kawai system is negative: it's an old design
and has no "bells and whistles." But, you can look at this
as a POSITIVE as well: "WOW, this is a system that is
BARE-BONES with NO BELLS AND WHISTLES!!"
