  1. Guidelines for boosting sub EQ with REW and MiniDSP 2x4 unbalanced

    REW Forum
    If I want to apply some boost to sub EQ to avoid the need to cut everything greatly to the same level (which is my current approach), what guidelines should I follow? I want to do generate auto filters in REW and where should I set max individual filter boost and max overall filter boost...
  2. Balanced or Unbalanced MiniDSP?

    Electronic Processing/Equalization Devices
    I recently acquired a QSC DCA1622 amp second hand to use in my HT rig. The plan is to use one of the amp's channels for a 2 driver IB sub and the second channel to drive a sealed Tempest sub. Both subs will present a 4ohm load to the amp which specs 500W @4ohms. I've tested the Sealed Tempest on...

  4. Behringer ADA8000 to convert Marantz 7007 RCA unbalanced to XLR Balanced for QSC RMX 850.

    Home Theater Receivers | Processors | Amps
    I am looking to amp my home theater with QSC PA style amps, the issue I am facing is converting the RCA amp pre out on my Marantz 7007 to a signal that is usable for the QSC amps. Looking to convert it to balanced XLR with the cleanest sound possible without any additional distortion. I have...
  5. MiniDSP 2x4 unbalanced question re output voltage

    Electronic Processing/Equalization Devices
    I was looking at replacing my SMS-1 with a MiniDSP 2x4 unbalanced. I emailed the company and they are recommending that I purchase the balanced version (which requires some rather inconvenient and inelegant wiring). They said that it is because the 2x4 unbalanced output voltage is only 0.9V...
  6. Unbalanced output to balanced input

    DIY Subwoofers - General Discussion
    I have a receiver (denon 2309) that has an RCA subwoofer output. I send that signal to a behringer ep1500 via an rca to xlr cable purchased from monoprice (the signal is always converted to unbalanced I believe). My question is should I use an unbalanced to balanced converter box? In short...
  7. Unbalanced HK Receiver

    General Service and Technical Information
    Hi. I got an old Harman Kardon 630 stereo receiver for cheap. Unfortunately, the left channel of both speaker outs is audibly louder than the right channel. I swapped the fuses for the right and left channels but the issue persists. Is there any additional troubleshooting I can do other than...
  8. Balanced vs Unbalanced

    AV Home Theater
    Unless I'm mistaken, unbalanced speaker connections are simply bare wire or connected to spades, etc.. I've seen the inputs on amps for unbalanced. What are the benefits of one over the other? Or is it just another adapter, like a spade, that attaches to bare wire? Thanks in advance!
  9. Unbalanced vs xlr balanced cables

    Remotes | Cables | Accessories | Tweaks
    I have 2 SVS PB13 Ultras and I have connected them with rca cables to wall jacks. The running length of the rca cables are 30 ft and 20 ft. I am considering switching to XLR cables as I read that I maybe losing signal strength because of the long cable distance. If I run dual XLR cables the...

  12. DCX2496 Unbalanced Output

    Electronic Processing/Equalization Devices
    I have just ordered a DCX2496 and am now working on the cabling required. All my sources and amplifiers have balanced interfaces, except for my subwoofers. One of the output channels from the DCX will drive my sub amps, which have unbalanced inputs. The DCX has balanced XLR outputs only...
  13. unbalanced to balanced converters

    System Setup and Connection
    I have a question about the unbalanced to balanced converters as far as do they apply fixed amplification or are they adjusting the voltage according to the input level they receive? Rite now I have my processor volume turned up high enough to get a 0dBfs level with movies into my 3...
  14. Balanced and unbalanced from the same preamp?

    Home Theater Receivers | Processors | Amps
    Hi guys, Just wondering, are there any electrical issues if you used both the balanced and unbalanced outputs of your preamp to feed your power amps? I'm thinking of investing in Denon's latest preamp, the AVP-A1HD. As you can see from the PDF, there are both types of outputs on the back, but...
