To the best of our knowledge the KCL system is at least 10 years old
and would be of such old and out-of-date-technology that we hesitate to recommend it.
Nevertheless, here is a description of the Kurzweil KCL system:
The heart of Kurzweil's class piano lab is the KCL
Teacher Controller. The KCL handles up to 16 student workstations.
A standard ethernet cable connects the individual headphone
boxes to the KCL Teacher Controller.
This elegant design greatly simplifies installation and
maintenance of the Lab because the ethernet cables can be
cut to any length and can also be EASILY REPLACED should
any become damaged.
The individual student pianos are equipped with small headphone
boxes called SI Units (Student Interface):
|| The SI Units (student headphone
boxes) are attached directly to the student piano, usually
underneath the keyboard. A stereo patch cable is connected
from the piano to the back of the unit. A stereo headset
with microphone is then plugged into the SI Unit.
Actual size of a student headphone
box (SI Unit) is: 2.5" x 1.25"
The KCL is equipped to control 16 individual keyboards
and can be connected (networked) to another KCL for
a total of 32 individual stations. The KCL is extremely
flexible, allowing the teacher to communicate, using keyboard
or microphone, to one student, several students, or the
The KCL Lab can be configured for groups of students
to work together (for example, duets or ensembles). Individual
groups include 8 pair of students or 4 groups of 4 students.
The instructor can enable or disable two-way keyboard or
voice communication between students. The KCL control
unit has no MIDI implementation which means that the Teacher
Control Unit does not send or receive MIDI directly.
Stereo headsets with microphones are available for $79.00
each. Sorry, no picture available.
The only physical connection between the student piano and the Kurzweil
system is the individual student headphone box and this connection
is strictly an AUDIO connection. Consequently, the Kurzweil Class
Piano Lab equipment is designed to function with any manufacturer's
keyboards. Kurzweil Music Systems does have several models of
digital pianos in various price ranges and with a range of features
which are especially suited for a Class Piano Lab. However, because
of the recent acquisition by Hyundai, we have not been able to review
and test any Kurzweil keyboards and consequently cannot recommend
any at this time. BUT, no doubt this will change shortly -- so stay
tuned for the next exciting episode in the KURZWEIL SAGA!!
[February 14, 2008. We have it on good authority that Kurzweil
is designing a Class Piano Lab keyboard which will HAVE THE STUDENT
HEADPHONE BOXES BUILT IN!!! We'll keep you posted.]
The Kurzweil company has had many adventures over the past
30 years. Originally founded by Ray
Kurzweil in the 1970's, Kurzweil was purchased by A &
G Music Corp. in the late 1980's. In 2004, Kurzweil was acquired by
Young Chang. However, in 2004 A & G acquired the company back
and was in the process of a complete reorganization until 2007 when
Hyundai purchased the company. In addition, Hyundai has reconnected
with its original founder, Ray Kurzweil with hopes of
a complete overhaul of products, company image, and most important
-- development of new and innovative products.
The long-and-short of all this messy acquisition stuff is that Kurzweil
class piano lab products have literally been unavailable for about
3 years. NOW THEY ARE BACK!! .. and according to Kurzweil USA's
main spokesperson, the Class Piano Lab equipment is at long last,
once again AVAILABLE. (August, 2008)
May 1, 2013. Until recently, we were assuming that the Kurzweil KCL class piano system was no longer availalbe.
The Kurzweil website had no information about it and stated that "The [KCL] does not yet have any
Knowledge Base entries created for it." See Kurzweil. However, just recently a KCL link has appeared on Kurzweil's home page under "Home Digital Pianos: KCL
Kurzweil's KCL Class Piano Lab system was never manufactured in Korea
but was designed and manufactured in California by JL
Cooper Electronics, one of the most stable and respected electronics
designer/manufacturers in the business. In addition to Kurzweil, JL
Cooper has also designed and manufactured other Class Piano Lab systems
