Could someone post a photo of an MA6200 mated to Bose 901 eq?

[Robvolz]

I know this subject just has been brought up, but only in written form

I just bought a MA 6200 up north of Seattle

I am trying to hook up my Bose 901 series II with EQ to them

I am trying tape Pre-amp out
Then amp in??

pictures would clear this all up
Thank you, I’ll owe you a beer when we meet someday

Pictures? Good luck. Maybe a owners manal in the AK database?

However just to add more confusion to your question.

McIntosh preamps have a very healthy ability to sing much more voltage out of their amp out jacks than almost all of your typical midfi preamps, just like Mac amps like a higher voltage driving them.

This makes the insertion of a typical midfi processor and bad idea between the preout and amp in.

Much better to use a tape loop. Tape 1 output to the Bose main input, then the main Bose output to the tape1 input. Since this takes up one tape loop the processor manufactureres will give you back a tape loop in their device.

You will then be able to engage or disengage the EQ by pressing the tape 1 button.

Had this issue with a client hooking up a Carver Sonic Hologram decades ago and it caused him much grief until he finally relented and hooked it up correctly.

I think what he's asking is where to connect the the Bose EQ in the MA6200 system. There are two places that are obvious. It depends on if you want the EQ ahead of, or downstream from the VOLUME control. Is that the idea?

Yes, volume control is nice

so much easier (and obvious) when you have dedicated Pre-amp and amplifier.

Can anyone sent a pic of a 6200 with RCAs going to and fro to the Bose EQ?

Sorry if I come across harshly, but come on man...

It's Tape 1 out from the McIntosh to amplifier input on the Bose eq and from amplifier output on the Bose eq to Tape 1 inputs on the McIntosh.

Thank you
I get real hesitant when I deal with expensive toys

my old Saab 9-5, I rebuilt the turbo on my kitchen island. Didn’t blink.

my friend buddy (that was his name) asked if I wanted to change the oil and filter on his Maserati quatroporte. Changing oil and filter I remind you.

I kept freezing up and second guessing myself.

so thanks to y’all for talking me through this.

 

[whoaru99]

Stop second guessing and read the back panels. The descriptions should match pretty much spot on.

In any case nothing will break in this situation, unlike screwing up an oil change.

Just follow the words/descriptions; it will be fine. You got this!

 

[Robvolz]

To me, this seems wrong
Tape out to the EQ
Then from EQ to tape in

in my mind that means tape must be selected to hear when I want to hear records


Isn’t power amp input the best choice?


again
To all you, this is old hat

to me, scary stuff.

 

[whoaru99]

You engage tape monitor 1 and leave it engaged, that's it. What ever source you select will then route through the tape monitor circuit through the eq.

 

[whoaru99]

Also, it appears the jumpers that go from preamp to power amp are missing. If you don't have the actual jumpers you can use regular RCA cables.

 

[Robvolz]

I had removed them because in my head, the EQ out should go into amp input

 

[Robvolz]

the jumpers are back

Keep in mind many receivers and integrated amplifiers did not have preamp out/main amp in provisions that the Bose EQ would have been used with in the day. In that case the tape loop was the only alternative for connecting EQs and other processors which is why many of these devices are equipped with tape in/out jacks and switching to replace the one that would be lost.

I agree with the others that the tape loop should be used - thereby allowing the EQ to be bypassed as desired.

The only external processors I trust to put in between a Mac preamp and amp are Mac's EQs. To many of the plethora of others just can not accept the higher voltage Mac preamps will put out or output enough to drive a Mac amp section to full volume.

If you want to hear nasty distortion just over drive a EQs input.....

A tape loop by design works with a level of 1 dB volt or .775 volts rms.

By using the tape monitor button to access the EQ you can easily switch it in and out if you would ever add a second set of speakers that would not like the Bose EQ.

Tape paths have been used for external EQs and processors since the 50's so really a well accepted strategy.

If the processor can handle the voltage then you should be connecting the Bose to the pre-amp out and power amp in. If not then you have to use the tape in and out circuits..to keep from over loading the Bose.
