    Default TRS to RCA?

    I have been looking to buy the AudioFire 2 soundcard recently, but I have just one question... how to you connect a 1/4" TRS to a amp that connects via RCA? All the converter cables that I have seen have been for the 1/8" TRS to RCA. Would that work if I just put a 1/4" to 1/8" jack like the ones for headphones, or would that kill the quality? Help please because I do want a FireWire connection.

    I doubt you'd notice any difference and if your worried making your own cables is dead easy.

    You should be able to pick these up at any good electrical store.

    Amazing cables for the price. Or you can get an adapter but you're better off with the cables.

    That's not what he needs, that's mono not TRS. It would have a 1/4" TRS connector with two RCAs.

    Two mono 1/4 jack to RCA.
    TRS (Tip Ring Sleeve) can be Mono or Stereo. TS TRS or TRRS.

    Sugested reading
    http://en.wikipedia.org/wiki/TRS_connector
    I'm quite familiar with connectors, thank you, however you are wrong.

    Hardware Features*

    * FireWire (IEEE 1394a) interface with 8' cable
    * Bus powered with 6-pin FireWire interface
    * External 12VDC power supply provided
    * 2 balanced " analog inputs:
    o 113dB (A-weighted) dynamic range
    o +4dBu / -10dBV nominal levels
    * 2 balanced " analog outputs:
    o 114dB (A-weighted) dynamic range
    o +4dBu / -10dBV nominal levels
    It says two balanced inputs and outputs meaning he does need TRS>RCA and not mono connectors.

    Look at the pictures you posted, they are two separate inputs and outputs line 1 and line 2, they are not mono connections.

    If that wasn't clear enough:

    Supports full duplex 4 channel in, 6 channel out operation at 24 bit, 96 kHz sample rate

    This says you can plug an unbalanced cable into a balanced port. It just acts like an unbalanced signal. I trust Harmony Central a LOT.

    I've also never run into any issues whatsoever running an unbalanced cable bought from radio shack in the style Karlos has posted into a balanced port. ever.
    It's the FAQ. Read it.

    I am aware of this, they are unclear in the description and by 'balanced' they really mean two channel 1/4" TRS use. It is a 4 channel in 6 out soundcard, so each line input is two channels and requires a TRS for the purpose of making that possible, it has nothing to do with a balanced or unbalanced signal.
