If you only have one set of tape in/out connectors, then hooking up two tape decks and an equalizer is going to be difficult. You could hook the "tape out" to one tape deck, that tape's output to the second tape, and the second tape's out to the equalizer, connecting the output of the eq back to your receiver....

Please see my answers regarding the hookup of Marantz amps and preamps.

It sounds like you've read one of my many posts on 901 deployment in the AV world.

Functionally, what is the difference between one amp with 'x' channels or 'x' mono amps? Nothing. Pre-outs don't know or care what else an external amp does.

According to this link http://www.ecoustics.com/electronics/products/new/642968.html those amps are 2- and 5-channel, respectively.

There was a time when I had two bridged-mono Carver Cube atmps (at a real 400 watts) pushing one 901 each but that was big time overkill.

I now use a Carver AV-406 (functionally the same as your MM7055) with the 901 EQ in between the AV Receiver's front pre-outs and two 110-watt channels. Other channels on the AV-406 pull subwoofer and surround back duties. My AVR directly powers only the center and surround speakers.

The MM7025 would work for you.

Blue wire connects to XLR pin 2.
Red wire connects to XLR pin 3.
You can find a wiring diagram on Shure's website.

XLR connectors are a two-wire plus ground system. Using a 1/4 inch to XLR adapter may not connect the wires correctly to your sound system input.

The A-T Freeway 200 Series has a 1/4" output jack. This would indicate a line level. A cable to connect the tip of the 1/4" jack to pin 2 of the XLR and the sleeve of the 1/4" jack to pins 1 and 3 of the XLR should work. The XLR should be plugged into a device that accepts line level.

Ideally, you should plug the 1/4" into a 1/4" or RCA jack that is designed for line levels.

Lets verify the simple stuff first. Make sure that the unit is set to use the "external" mic rather than the internal. If it is set that way, then there may be an internal problem. I will look up the service manual and get you more specifics should they be required. Please update this with the status.

Thanks,
Dan

Undo the set screw near where the xlr cable would connect. Use needle nose pliers to gently pull out the connector. Check to see if the connections are solid. Some of the sm48 have switches for on and off, so it could be that as well. hope this helps.

Does your Marantz have an "optical" or "digital" out?

If so, use them. Assuming you have a quality receiver/pre-amp/amplifier it will have it's own D/A converters.

If you plug into the receiver's CD inputs you will be using the D/A converters in the Marantz.

If you plug into the DVR/SACD inputs - it depends on the receiver et al.

Try both. See if one sounds better. Select the one that sounds best. For a top-notch system you need high quality from cables to receiver, and speakers. You system can only be as good as your weakest link, so what sounds good/great to your ears, that is the best!

The Samson CO2 is a condenser (also called capacitor) mic, and thus requires phantom power to operate. In order to apply phantom power, you must have a board capable of handling an XLR connection, and supply phantom power. Usually there is a switch located near the XLR-input jack on your board - if you post your sound board type, more help can be given.
