MEN220 with Serial Number starting ADM

When the MEN220 is installed between the preamplifier and the power amplifier the digital to analog processor is always on, even when the MEN220 is switched to Bypass. The Bypass function of the MEN220 only removes the Room Perfect filters, not the analog to digital and digital to analog conversion of the signal passing through it. The MEN220 digitizes the input signal immediately and the A/D and D/A process cannot be bypassed when it is installed between the preamp and the amps.

okay, so say you want to use the Men220 for room correction as it's primary purpose. The signal is going to go through it's DAC. So then, what is the point in spending money and effort on a great DAC at the front of the chain if the original signal from that DAC is going to go through another conversion in the Men220? Wouldn't the sound signature of the DAC at the front of the chain be changed? For example, lets say I found a DAC with a warm sound signature, will that warmth be eliminated by the time the signal goes through the Men220?

Capitalcityguy.......The last DAC in the signal path will impart its sonic signature on the final analog conversion. That can mean any number of things but hopefully it remains as invisible as possible.

hmm. well my system can get hard sounding on some recordings. Not sure if it is a source issue or room issue. So I was either going to get a warmer analog sounding sources or the Men220. My current source is a modded Sony Hap 1zes music storage/player/DAC. Love it's simplicity and one box approach, it is simply ideal. But at the same time I want listenable sound with some of my favorite music. So anyway, I guess I have to decide which route to go. thanks for the input guys.

I tend to believe so, that it is indeed as invisible as possible.

Every time I change filters or something on the Esoteric player or every time I have changed tubes on the c2500, I have always noticed changes on the final sound coming out from the speakers, for better or for worse.

So even after applying all filters, room corrections on the MEN220, something always changes in the sound chain.

That simple but not necessarily very scientific method, has convinced me of the unit being as transparent or invisible as possible.

In the new version are there any more "settings" for the crossover ? In the original there were not enough to use it as a crossover for my Jubilees.

Can you give us more details to what you are trying to achieve? There are no changes in crossover settings. However, the PEQ/EQ voicing tool that McIntosh provides has about 8 or so filters.

I used the MEN220 to crossover from the Basshorn to the Mid-horn & Squaker. The Mid-horn & Squaker used an ALK Engineering Crossover. I also used two MC275 amps, each running a channel to bottom (bass horn) and top. I delayed the top about 8' to time align the speaker. Best sound I have gotten period.

Then I moved homes, for work. All these newer houses do not have adjacent corners, and I put the Klipschorns in storage. I will be moving again, so I will be looking for a room (or will make false corners) in the next home.

I rambled at that to say, I think the Jubilees only can benefit from the MEN220.

Whatever.......The JBL 250Ti Jubilee is a 4 way speaker. The MEN220's active electronic crossover is a two way design. One way you can effectively use the MEN220 as a crossover with the Jubilee is to drive the woofers independently from the MEN220 Low Pass outputs and feed the remaining three drivers from the MEN220 High Pass output while continuing to use the Jubilee crossover network for those three drivers.

A second way to deploy the MEN220 with the JBL Jubilee is to use the MEN220 Low Pass output to feed a subwoofer and feed the Jubilee full range.

The Jubilee is a two Klipsch sorry for any confusion

When the MEN220 first came out it did not have enough filters to work compared to a EV DV-38. At the time I asked on this forum and asked the factory (Chuck)
My question with the upgrade are there any more filters ?
If needed I can provide the settings I need in the DX-38

Whatever.......Opps. I'm a JBL fan so when I read Jubilee I immediately thought of the JBL 250Ti Jubilee.
