The Bozak Concert Grand is a loudspeaker dreams are made of. I was just a boy, but I remember to this day the impressive pictures of them in Audio magazine. I thought they must be the best loudspeakers ever made because they were so big—they would let more of the music come out. I suspect the Bozaks beckoned to me in some primal way, just as those giant construction trucks do—the ones that. BOZAK MODEL CMA-10-2DL 2DLS STEREO MIXER PREAMPLIFIER OWNER'S MANUAL $ 13.59.

Upgraded New Bozak Cma 10-2dl Rotary Dj Mixer By Mr. Beck Approaching Urei 1620:
$2,200
This mixer was assembled using many new old stock parts, factory service parts, or obsolete original
material built and designed during the 1970s-1990s by the U.S.A. Bozak Company located in Connecticut.
Any part containing the Bozak name, logo, or part reference number including but not limited to main
circuit boards, plug in electronic cards, chassis, faceplates, etc is original material as designed by the
U.S.A. Bozak Company. Parts containing the HB or HBG identification logo or part reference number
are owned and used with permission from HBG Audio Specialists. New or obsolete universal parts
produced by manufactures such as Alps, Allen/Bradley, Amp, Aromat, Beyer Dynamic, Buckeye,
Centralab, Chicago Miniature, Frako, Motorola, RCA, etc are original as used in U.S.A. Bozak factory
products. Any universal replacement parts such as Transformers, Potentiometers, Transistors, Resistors,
Capacitors, Diodes, Switches, etc have been selected from
today’s highest quality parts manufactures. The buyer/user is completely responsible for the proper
installation and any damages that might occur or be created from same. The mixer is guaranteed to not
be DOA if no shipping damage is present. No other warranty is expressed or implied. In no way is this
mixer associated with the company now using the Bozak name and producing Bozak brand electronic products.
As the header states this is a 100% original U.S.A. Bozak brand mixer built with original U.S.A. Bozak
factory obsolete material and factory service parts. The chassis is a smudge proof factory only 110/230
volt DL unit that was designed originally in the early 1980s for export use. It is identical in every way to
its counterpart U.S.A. model with the exception of being able to operate on different line voltages. For
the first time, this mixer has a one of a kind upgrade never available before. Here is what Mr. Beck wrote….
'The main complaint that was heard over the years from so many service facilities and I even get today
is the fact that the potentiometer replacement on U.S.A. Bozak brand mixers is so cumbersome and time
consuming. This issue was addressed for several service repair centers years ago but was never added to
the production line of mixers. A small card accepted the RK40 potentiometer that was installed with pins
instead of the production style solder loops. This made it possible to replace 1 level control without tearing
the entire front panel apart and the addition would save time and costs for both the customer and the service
repair centers. Because most Alps replacement potentiometers are available with pins instead of solder loops
I have designed a card to accept both the black RK40 and blue RK27 level controls. This is the first mixer
other than a handful of prototypes and service repairs that ever received this option. If you need to replace a
level control at any point in time in this mixer you will not be required to cut, chop, or modify anything to install
either a black RK40 if still available or the now more commonly used blue RK27 Alps potentiometers. I
have added this for ease of replacement by technicians and less expense encountered by the customer.'
This mixer features all new
* Smudge proof service chassis with variable voltage option.
* Original U.S.A. Bozak internal electronics.
* Black RK40 Alps potentiometers with replacement boards.
* Alpha soft touch balance controls with resister upgrade.
* Bourns military bass and treble control potentiometers.
* Cue switch with factory wiring.
* Updated power supply card.
* All new rear panel jacks with riveted heavy duty plates.
* Factory knob set.
The mixer will come configured as the original 1976-1989 factory DL mixer that was offered with 2
phono, 2 auxiliaries, and 2 microphone input channels. It is upgradeable to 4 phono inputs with the
addition of the 3rd and 4th channel 919 phono preamp cards. These cards when added makes channel
Aux 1 and Aux 2 become selectable phono channels. The only modification to make either channel
become a phono input is a simple repositioning of the rear input wires as explained in the owners service
manual and of course the purchase of the required 919 phono preamp card. Phono channels 1 & 2 can
become Auxiliary channels by removing the preamp card and replacing it with a jumper or jumper card.
All of the front end cards as pictured are 100 % original Bozak inventory from the 1970s-1990s. All
cards are new and were recently tested or assembled by Mr. Beck carrying new factory or factory

Upgraded New Bozak Cma 10-2dl Rotary Dj Mixer By Mr. Beck Approaching Urei 1620:
$2,200
Today’s Bozak range is inspired by the DJ’s who themselves were inspired…Bozak is truly Audio For The Soul.
Bozak Cma 10 2dl Manual 2016
Rudy Bozak was one of the all time great audio pioneers spanning the 1930’s to the 1970’s. During the 50’s and 60’s the musical map was changing forever, from Rock n Roll to RnB and in the 70’s, RnB then went up-tempo and Disco was born. The rest is pure club land history. The Bozak CMA-10-2DL was the first commercially produced DJ mixer, ground breaking by being larger than life in stereo, but the single fact that finally the DJ had a mixer designed for their requirements. Engineers and DJ’s alike fell in love with the mixers functionality and the unique smoothness and warmth! Featured for so long in so many DJ booths, Nicky Siano’s Gallery, Studio 54 and Larry Levan’s booth at The Paradise Garage, the original Bozak mixer earned its unique place in DJ history. The legacy of the Bozak lives on today, in fact most of the modern manufacturers have copied Bozak’s original mixer in some shape or form but have never quite matched its unique sound.
Bozak’s use of discrete components gave the mixer a unique sound that cannot be re-created with today’s integrated op-amps. Analog Development has designed to the same exacting topology that made that early audio sound so warm, exciting and made the stereo image so dynamic. All the Analog Development products use high performance analogue control circuits using individually selected discrete components.
Analog Developments have faithfully reproduced the feel of the classic rotary controls with its simple but intuitive layout. Every care has been taken to faithfully reproduce the warmth and stereo separation that has made the Bozak name what it is today.
Functionality has been improved where necessary to accommodate today’s DJ’s and sound system engineers with special attention being paid to the connectivity and tactile feel of the product. The superior dynamic response makes the control smooth and predictable whilst the Bozak frequency-dividing technology gives individual tone control, allowing the user to isolate beats, vocals and the high hat as well as adjusting the overall tonal quality. The crossover points of the EQ have been carefully selected to yield a more natural sound and to emphasise the artistry in the musical production.
The producers and musicians, having spent so many hours perfecting their productions, would love to hear them played back in a club so the tracks can be heard to their fullest potential. The natural warmth of the Bozak brings out the dynamics of the sound as never heard before, precise and without the aural irritation and listening fatigue common to so many DJ mixers.

Although often imitated but never surpassed, the Bozak mixer was born in a golden era when sound was pioneered by engineers keen to discover new boundaries. The new Bozak products remain true to the design topology of those times, add in today’s engineering technology and we have achieved a unique sound as only dreamed of by its clones.
The original Bozak mixer was available in a few different guises and it is commonly felt that the product’s life was cut short and never reached its full potential for the DJ.
Today we utilise the original CMA-10 circuits as the bedrock of all the new Bozak products ensuring parity with the Bozak sound and quality but carefully updated to perform in tandem with modern players, system controllers and amplifiers and constructed to current safety standards.
All our products are hand built in our UK factory. All the Bozak products are fitted with the highest quality components selected for the best possible audio performance. Fitted with ALPS RK27 Blue Velvet pots, carbon resistors, environmentally sealed switches, polyester mylar capacitors and ultra low noise hi-fi grade worldwide toroidal power transformer all culminating in Bozak’s signature rich warm sound.
