    Hi everyone, Im new to the forum.

    my question is about low latency monitoring and how to hook up my rig.

    im using logic 8, dual 2.7ghz g5 4.5 gb ram.

    recording source in>dav bg1 pre-amp>(soon to be LynX l22, or similar) into logic 8 then lynx22>m-patch passive volume controls>monitors and headphones.

    my question is that when recording through this chain i expect latency. how do i monitor without latency say recording vocals? im not sure how to monitor directly ? at the moment my chain will be going through logic and picking up latency i suspect by the time it reaches my headphones, what can I do?[/b]

    Hi, and welcome to the forum!

    Are you tracking or doing single-pass recording?

    If single-pass (no concurrent replay of recorded tracks), you could use a pair of balanced Y-cables to split the output of the BG1 to both the input of the Lynx and also the balanced input on your M-Patch 2. There is no L-R mixing with this configuration, but you could use the mono switch on the M-Patch 2 to avoid the two separate input channels appearing in separate ears. I assume you have the M-Patch 2 outputs wired to give you a choice of headphone amp or loudspeaker monitors for recording or mixdown respectively. Re-connect the M-Patch 2 inputs to the Lynx outputs and switch back to stereo for mixdown.

    If tracking, you have more of a problem, as you need a mixing function to mix the live pre-amp output and replayed tracks from Logic. A simple 2, 3 or 4-channel line-level stereo mixer would work here, depending on how many channels you are tracking. Mixer sound quality is not of the first importance, as it is not in the recording chain. Use Y-cables as above. Logic 8 can replay already recorded tracks compensated for latency (buffer size, etc), so connecting up the live signals directly to your monitoring should ensure that your tracks line up properly.

    yes im doing single pass recording.

    forgive me but im still confused. i get using the y cables coming out of pre into s-card and monitor/headphone. but i dont understand how i can hear the song coming from logic whilst doing this?

    I'm confused by your confusion. Single track recording, you do not need to hear what has been recorded, you only need to monitor the input you are recording. If you are tracking then that means you are recording a new part over or onto a new track of an existing recording. Which is it?

    As jg says, that means you are tracking, even if it's only karaoke. Follow the second set of instructions about using a simple mixer.

    The alternative is to save up for a higher-spec audio interface that lets you mix real-time input with replayed tracks out to headphones.
