H4n noise preamp

Wow, that's a long adapter. ( the Rode adapter is about 1.5 inches long )

Just out of curiosity, your adapter doesn't have a "pad" ( which lowers the signal strength ) in the first part of it's connection? ( it looks like two connectors fitted together )

In your picture you have the Marantz MIC / LINE switch set to LINE, which would greatly reduce the signal strength.

The switch should be lining up with the OFF position for a MIC level signal. ( without phantom power )

the cable is 3.5mm to female xlr and so I attached a male to male xlr to allow it to fit the marantz

ill test it but i believe it didn't get any signal either

the max signal seems to be around -40dB



im yelling into the mic at around 1 inch in one of the pics
 
I'm thinking it might be the XLR-F to 3.5mm adapter cable. I'll bet pin2 of the XLR is connected to the TRS tip, pin 3 to TRS ring, and pin 1 to TRS sleeve. Remember in a conventional stereo TRS plug left is on the tip and right is on the ring. When you send a stereo mic input a mono signal, you short tip and ring together so the audio ends up both channels equally. Since the receiver expects to send its mono output to a stereo mic input, I suspect the oiutput jack is wired with tip and ring connected together. In the XLR pin 2 is signal hot and pin 3 is signal cold. I suspect that the two are getting shorted together at the other end of the cable when plugged into the receiver, killing your signal. Get a Rode VXLR stereo 3.5-> mono XLR adapter connected to the receiver with a conventional stereo TRS/TRS cable and I'd suspect it will work. To work properly mic output TRS tip goes to XLR pin 2, TRS ring ALSO goes to XLR-2, TRS sleeve goes to both XLR-1 AND -3.

ill definitely do that, it says that the xlr is hot, is that what you mean?

Pin 2 hot is good but what is going on with pins 3 and 1? I still suspect that pin 3 is shorted to pin 2 when you plug it into the wireless receiver. What is the cable originally intended for? A cable intended to plug into an XLR input such as on your recorder will already end in an XLR male connector. Since yours is female, it is likely built to send an XLR output into the transmitter.

the rental place gave me the cable to connect a handheld mic going from 3.5mm to xlr female
the only one that came with the receiver was the 3.5mm to 3.5mm

As I figured, the cable you have is to connect a mic's XLR OUTPUT to a transmitter's TRS INPUT. Different thing from what you're trying to do now. Get the Rode VXLR ($20) and try connecting using it at the recorder along with the TRS-TRS cable they supplied with the receiver.

one more thing, the seller I bought the 661 from did not include an ac adapter.
could i use any adapter rated 5v and 1.5amp to upgrade the firmware?
would just 5v and 1.5 or less amps work?


thank you!!

Anything rated at 5volts and at least (NOT less than) 1.5 amps should work as long as the polarity of the DC plug is correct. A glance at the manual specs online reveals that the part number of the power supply is DA620PMD and a google on that part leads to any number of sources where it's available for $35 or $40, should you want to get the OEM part.

What is a safe maximum amperage though? I have some 5v 3am and higher plugs

The rated amperage is the maximum it is able to deliver. The actual amperage delivered depends on the load impedance of the device it's supplying. If the device draws 1.5 amps at 5 volts, that's what a supply rated at 3 amps will deliver. Think of the rating as the available amperage, not necessarily the delivered amperage.
