How do I connect my Yamaha EQ-70 to my Yamaha RX-V2400 receiver?

Hi Tony mucci, to connect your Yamaha EQ-70 equalizer to the RX-661, you must use two double RCA RCA cables and the Line IN connection of the EQ-70, you go to the RX-661 MD / CD-R Rec connection and the Line Out connection of the EQ-70 you go to the MD / CD-R Play of the RX-661
This equalizer will work with the analog audio signals, but not with the digital ones
I hope you can connect it

Hola Tony mucci, para conectar tu ecualizador Yamaha EQ-70 al RX-661, debes utilizar dos cables RCA RCA dobles y la conexion Line IN del EQ-70, vas a la conexion Rec de MD/CD-R del RX-661 y la conexion Line Out del EQ-70 vas a Play de MD/CD-R del RX-661
Este ecualizador va a trabajar con las se?ales de audio Analogicas, no asi con las digitales
Espero lo puedas conectar

Sorry, it doesnt look like you can hook up an external EQ while still using the amplifier section of the yamaha. Instead, You would have to use the preamp out to go to 901 EQ, out of the EQ into another stereo amplifier, then to the 901 speakers. Personally, to power the 901's properly, I'd use another external amplifier. You will barley get 75watts per channel out of the receiver to power the 901's

tape out to line in on eq, line out from eq to tape in on receiver, use tape monitor switch to make eq work

The EQ is connected via one of the Tape loops on the amp (rec out from EQ to play in on amp,rec out on amp to play in on EQ). You then switch "Tape Monitor" on to hear the sound with the EQ settings applied. You can also connect it across Pre out and Main in should you have such sockets. I'm pretty sure it will only affect the main two front channels and not the surround channels.

from cd analog output to input at the yamaha, then from output to dvd/cable/ cinch input at the Denon.

Connect through the tape monitor jacks and if a tape deck is used connect it to the eq! Check your owners manual if you still have it or download one.

Through the tape in/out jacks and also push the tape monitor button when using the eq!

download the amp's manual & you will find on page no. 7

If your receiver has a TAPE IN you can connect the EQ to that, and it will work just fine. Or if you have main LINE OUT / LINE IN, you can create your loop there.
