Input types and input levels...

[yarrick]

Hello,

I am getting into computer based recording and have come along a few *basic* questions that I am unclear on, and I hoping I can get them cleared up here.

I recently purchased a M-Audio Quattro usb interface for recording into Cubase SX. The Quattro is equiped with 4 1/4" TRS inputs and 4 1/4" TRS outputs.

I am planning on feeding all of my inputs (guitars, vocals, etc) through a Mackie CR 1604 mixer (to use its pre amps) and then either out the channel access "ports" or the mains and then into the Quattro.

So, since the inputs on the Quattro are TRS, do I need to get a 1/4" stereo(TRS) adapter for my 1/4" mono(TS) cable on the end I am inserting it into the Quattro, or will a standard 1/4" cable work fine?

Also, should I run the input levels on the Quattro at +4dBu or at -10dBv?

Thanks for your help! Its much appreciated.
Paul

Use TRS, you're going to use the tip only in the inserts of the mackie to send to the quattro. I would guess that even though you're only using half of the balanced jack from the mackie that it is still a balanced connection happening (i think). As for the input level you could use +4 but just make sure to keep that level the same don't mix a -10 input with a +4 and visa versa.......noise and distortion problems will occur.

good luck

No way. You need 3 wires/contacts for a balanced signal!
Elementary, doctor Watson.

Never used a Quattro but in general you can simply plug TS cables in a TRS input for unbalanced operation.

By the way. please don't cross post. Choose your forum wisely and post your question once. That's what we do here.
