How do I connect Active speakers to my Denon 3805 AV receiver?

I have two front speakers that are powered studio monitors that I'd like to use as my Left/Right. I made XLR-RCA cables that are going to run from the speakers to the receivers pre-out. The speakers are Genelec 1037C's

    Hi again. No, the DACMagic Plus is a digital to analogue converter. Sure, it has balanced XLR outputs and an unbalanced output, but no analogue inputs. You are not dealing with digital signal here, just analogue, so you need a device that converts unbalanced high impedence signal (your amplifier pre out) to balanced low impedence signal (XLR to the Genelecs) Great monitors by the way. I run Genelec monitors myself. Cheers, Don

Your Genelec 1037C monitors are professional design with balanced inputs. Balanced inputs expect a low impedance signal with pin 1 earth, pin 2 hot and pin 3 cold. Because the Denon amplifier supplies a pre out for the front speakers (the first pair in the set of pre outs) at 1.2 volts and high impedance, you will need to convert the signal close to the amplifier with a stereo active DI box. Plug the pre out directly into the input of the DI with a SHORT lead and then plug two standard balanced microphone type cables ( XLR to XLR) into each of your active monitors. You cannot make a cable that is RCA to XLR by shorting pin 3 to earth to do this job properly. The inputs on your Genelecs expect a signal in the range -6dBU to +6dBU for rated output. A suitable DI box would be for example a Klark Teknik DN200. Hope that helps.
Cheers, Don.

How to connect the speakers

There are a total of 9 sets of speakers that can be connected to the unit! Refer to page 15 of the manual for detail, as I don't know whether you are connecting main, surround or auxiliary speakers. As a minimum, you would connect a single pair to the 'Front' connections. See the link to the manual.

How do I hook up my bose 901s to this unit?

Well the basic connection of the speakers would be the same as another stereo speaker pair. Wire the left and right speakers to the L/R Front Surround speakers on the Denon.

With the 901's I am assuming that there is an external equalizer supplied by Bose. Typically this EQ is installed in a tape loop on the receiver/amp so that it is ahead of the power amplifier that drives the speakers. This EQ needs to be there to attempt to get reasonable frequency response from a speaker that has only 4" drivers. I'm not sure I see any reasonable way to make the EQ work with the Denon AV receiver. You'd likely be better off using the Bose speakers in a dedicated 2-channel stereo and getting a set of speakers for the AV usage.

Make sure you didn't get the video line out confused with one of the audio lines.
If using composite video the connection should be yellow and the left and right
channels should be red and white

I cannot connect my bose 901 series v1 active equalizer to my denon av surround receiver avr-891

Short answer from personal experience.

There is no way around this part. Get a separate power amp for the 901's if you want to use them in a multichannel way or alongside non-901 speakers.

The reason: You can't use the Active EQ (or ANY processor) in a tape Monitor loop with anything but 2-channel stereo material. As soon as you activate the loop you lose digital sources.

Adding to YOUR particular problem is that the Denon doesn't have a volume-controlled pre-out to feed that amp. If you want to deal with controlling the separate amp volume manually you COULD connect the Active EQ between DVR Out and the 901 amp IN but you would have a stereo mixdown instead of true front channel from the speakers.

Bummer.

I have a Denon AVR 3805 receiver. It does not have a Main Amp in or a pre Amp out in the back. How do I properly hook up the Bose 901 equalizer to this receiver? I use the 901 speakers as surround...

By properly, you must mean WITH the Active EQ.

According to this picture, you're in luck BUT...

(Short answer from personal experience.)

There is no way around this part. Get a separate power amp for the 901's if you want to use them in a multichannel way or alongside non-901 speakers. A good 100-wpc amp will do. (I like Carver)

Connect the Active EQ between the Front pre-outs and the amp input. Run speaker assignment, levels, etc and have fun.

Helpful Hint: If you don't have sufficient between-speaker room for proper reflection off the front wall you CAN turn the 901's around and you won't believe the amount of air these things push! I have actually felt it ten feet away after explosions or crashing ocean wave sounds. Now THAT is multi-media.

How do you connect power amp to av

I presume you want to use it to drive speakers from a source controlled by the Denon??? Probably the Front channels? We'll assume that's it...

Run RCA cables from the Pre Out jacks to the NAD's L and R inputs. If it has a volume control, set the NAD to its maximum volume (for consistency *), run through the setup for levels and you're done.

* If it doesn't have a volume control it's already set to max. That's normal for power amps. Your receiver / preamp controls the volume fed to them.

BTW: If you're thinking of using two sets of Front channel speakers simultaneously you'll have to choose a level on the NAD that will match up with the others in volume.

No surround sound from my Denon 3805

well as long as all signals are routed through the Denon your on the right track, now what else you have to do is connect all devices to the reciever do not loop one device through another. Also you have to try the different surround fields to hear the one you like the best for music I use 5Ch stereo for movies the surround field varies based on the type of movie

Connecting Bose 901 series iv to Harman Kardon AVR 254

Most HK av receivers have pre amp out,power amp in with metal jumpers connecting them for the main or front channels. that would be the best place to hook up the EQ on a AV receiver. If your receiver doesn't have pre out, power in jacks , you can use tape monitor .record out playback in. The tape monitor option is best for stereo use , as the active EQ will charge all speakers in tape mode, possibly damaging other speakers.I run my 901 s with a seperate pre-amp,power-amp hooked up to my Denon AV receiver that way i can run in surround w/standard speakers
