Hi qazx

This system is proprietary stuff, and is serviced and installed through a dealer network only. The software actually comes with the product, so if you didn't get a copy with the equipment, I am sure that the manufacturers will oblige you. Another approach is to get another agent on the go, or at least if you tell SpeakerCraft what has happened, they should be sympathetic and supply you a disc of the software. Goodluck, let me know how you get on.

What do i need to program a speakercraft mzc64, mzc66, mzc88 ?

This info is meant for all the Speakercraft MZC controllers.

The software used to program the mzc controllers is called EZ TOOLS the latest version of which is 401. This version handles both the IR database versions released in these units.

V313 is the older one and 401 is the latter.

you will need a laptop which runs windows, EZ tools is native to XP but should work emulated under later versions of windows. I have this running on linux under wine with some basic command line mods to allow the com port to be seen by wine, this works well although some of the rendering of graphics looks incorrect but still good enough to use.

You also need a cable with a female 9 pin d sub at one end and a stereo 3.5mm jack plug at the other, use screened cable.

The correct port to use on the back of the mzc is the jack com port not the dsub rs232 port.

There is no way to copy theprogram off a machine, you have to either have the origion project file that works in ez tools or start from scratch with a new file.

If you need to transfer from one mzc to another one if the first mzc unit has failed hardware, you can remove the rom chip which is plugged into the control board located behind the front panel. This can be swapped over to the other mzc and is the identity of the mzc controller.

For making up a communication cable use the following pins..

Pin2 dsub to tip of jack
Pin3 dsub to ring of jack
Pin5 dsub to earth jack

Trust this info helps.

What causes cracking, popping sounds on most zones of a MZC 66 amplifier controller?

Try this to isolate where it is coming from. Either the zone amps are defective, which is not likely, or the main amp is at fault. Hard to believe they are mis-wired, they typically are foolproof in this area.

At the main controller, try the two zones that are good and plug them into the 4 bad zones one at a time and see if you get the same symptom. If you do, then it is not the main controller and something common to the 4 zones is causing the issue. If they are wireless, then you my have interference so check if you can select different channels.

Oh boy, you have your work cut out for you. With a whole-house system you have a zillion opportunities for noise and hum to creep into those miles of wire. Start with total disconnection of as much as possible and see what source or output opens the door for the noise as you add it. Then evaluate the cabling for routing near or parallel to power sources, motors, magnetic fields, shielding in general.

The track light thing plagues me, too, for analog sources only. I just work around it by not using track lights when critically listening.

I'm thoroughly confused on how to hook up a tuner/receiver to put music out through the MZC-66 amp. All of the keypads and connections to them have been installed, but I have inputs for sources on the...

Shame on your Speakercraft dealer for not having installed this system for you or at least telling you how to hook things up! (You did get this from an authorized Speakercraft dealer, didn't you?) As you know, the MZC-66 comes with a 40 page user guide that will show you how to connect the system in your choice of several different ways. You gave very little information as to what keypads you have, what sources you want to connect, or why there is even a standard stereo receiver involved in this picture at all. The MZC is a custom installation product, designed by and for custom installation specialists and it has sooooo many ways to be installed that it can be used in just about any way you might want.
The simplest answer for you right now is that each of the inputs is paired with a "loop-output" which allows you to connect your source first to the MZC, and then (with another patch cord) to another preamp (or in this case, your receiver). You said that you only needed six zones, but the receiver adds in to make seven. Why do you want the receiver in the picture, again? Just for the tuner? Or do you want to use the amplifier in the receiver to power one of your rooms? (Remember, the MZC has pre-outs for every zone!) Depending on what make and model receiver you have, you can do any one of several different methods of making the two units work and play well with others. Again, I go back to the whole authorized dealer thing. With something like this, maybe it's best that you call in a custom installation pro who does this for a living to do this the right way. Too many potential ways to fail in an effort to save a buck. SpeakerCraft dealers are the pros who know how to make these things jump through hoops. They are the ones who put SpeakerCraft at the front of the line in distributed music systems. This is an advanced enough product that there is no way to tell someone the "one" way to make it work. Besides, unless you have just the most basic of keypads, how do you even plan to program the keypads to operate your source equipment? What is it that you want these pieces to do? What keypads do you have? Do you want the keypads to operate the source components? Will you use any of the video distribution functions? Will you use the doorbell or muting functions? How much experience do you have with finessing this kind of thing? Sometimes, it really is best for the DIYer to call in the pros... I just had to call a plumber, myself. It killed me to make the call, but I was wasting too much time and getting nothing done! You should start by calling the SpeakerCraft dealer where you bought the MZC-66. Good Luck!

I am a service engineer and have serviced a few of these units, you can send it back to speakercraft direct but they will charge you an arm and a leg for it, they are very 'cloak and dagger' about supplying parts and service info to anyone else including dealers.

I must say from the outset that these units are not a straight forward amp like some of the posting are suggesting... any professional engineer will not be able to diagnose a problem for a written symptom. these systems require a programmer via a software driven interface to set them up which only a dealer will have. so in some cases a re program can solve the issues.

The amp's (6xstereo modules) are very low powered at about 5w per channel so they are a common problem and each one cost's about £100.+VAT and then labour cost's, but they are loaded with a very complex matrix system for looping video and audio plus the CAT5e localised Keypad's... these are £5K systems when new, but you probably know that.

One way for you to get an better idea of were the problem might lie is to find a pair of powered speakers like PC speakers and connect them to the 'Pre-Out' connections on the rear of the unit located directly above the EZ-PAD connection on the rear.

You should be able to hear audio out of these outputs (one for each zone) and depending on the zone you connect to you will hear the corresponding audio that is selected in that area on the keypad.

if you do hear audio from each zone but not from the speaker outputs then it could be a number of problems probably caused by one or more of the AMP modules failing (which is common).

If you power up the amp with it connected and don't pass any audio through it, put your ear right up to the speakers in each zone and you should hear a VERY faint hissing coming from the speakers (which is good). Which ever zones are not emitting that hissing correspond to the amp modules that are faulty.

If you can't get any audio from the pre-out's on each zone on the rear of the MZC66 then it could simply need a re-program.

sometimes when a amp module blows it takes out another board and they are expensive.

This won't fix the problem but may go some way to helping you get a better idea of the problem if you haven't already.

Many thanks.

If your installer is an authorized agent or dealer of speakercraft product, it has a 2 year warranty. What type of problems are you experiencing with the system? Do you have a single 8 zone system or are you daisy chaining two units? post a comment, and I can do some research for you. I am an integrator and it's quite possible to have system failures do to a number of causes relating to all sides of the product. Firmware, Software, Hardware, Programming, as well as power failures and wiring issues all can play a part in creating a real headache. I have had systems in the hundreds of thousands of dollars crash due to one conductor of one wire in a 30,000 + sf home. And it is very time consuming as well as aggrivating to all concerned. If I can help in any capacity, I will gladly do so. If your installer has your confidence, that's 80% of the battle.
