Follow the instructions below to hear individual input channels through your headphones or control room monitors. Depending on your model, however, these steps may vary slightly.

The angle of the microphone will help avoid reflecting sounds reaching the capsule of the mic on the top panel of the PAA2 or PAA3. You may also choose to have it pointing straight, or any other positions, however it will only lock into place at 45 degrees.

As long as the cables are wired correctly you should not have any problems outputting the pink noise.PAA3

The 3 numbers you refer to (300/600/1200) are actually the RMS/Program/Peak power handling wattages of a speaker. The RMS (which is also known as continuous power) value could be described as the power handling of the speaker if a constant sine wave was sent through the speaker for a long period of time. It is not a real indication of the power handling of the speaker when real music is fed to it, though. The Program value is based around the occurrence of a complex program signal being sent through the speaker (ie. more like real music). The Peak is the absolute maximum power handling (but only for extremely short periods of time). Of course typical audio signals are ever-changing, so the power should generally be somewhere in between the RMS and Program values.

The USB Helix Boards are plug-and-play compatible with all Mac computers with OS 9.1 or above, provided the language of the operating system is English (other languages’ OS may vary). If you have an even later version of OS, you will also be able to use the program “Garage Band”, which will allow for easy recording and editing of tracks from your Helix Board.

It’s normally quite okay to use very long cables for the majority of our products. AC power (120-240, 50Hz/60Hz), usually works fine for a very long cable installations. The most important thing is that you use proper rude cables for this. If you are using a typical home AC cable, you should change it for a rude AC grounded cable (the ones with three blades), and make sure that your wall AC connection is strong enough so you can use long cables (usually this ones works good with long cables, but most of them are not build on constant AC consumption like the ones from your speakers). If your AC connection is not strong enough, find one that can give you a very good AC connection (as close at the main connection point from your AC distribution connection from the electrical company, the better will be) and bring you a very good AC supply, and no drop outs at your speakers or at your AC fuse (you can blown it). Your device will undoubtedly require a constant and strong AC supply, so make sure that your connection is strong enough so it can have a constant AC connection.

The main (and most interesting) feature in the upgraded Helix Board FireWire MKIIs is the Pre/Post switch, which allows the user to swap the streaming input channels to computer from pre-low cut,- EQ to post-EQ, post-fader.

Both Channels 1 and 2 on the Firefly 302 feature 1/4″ and RCA inputs, however only one of these jacks can be used at any one time. Using both simultaneously will combine the two signals as one, however certainly won’t cause any problems.

Voltage and signal transients (peaks) are sent through any circuit when equipment is powered on or off. These signal surges can be potentially damaging in the long run to components like power amps and especially speakers. An effective prevention is to think of the flow of “sound material” or program from its source to its destination. Always turn the components on in the direction from source through destination (i.e., first plug in mic, then turn on mixer, signal processor, and, finally, the power amp/speakers). Conversely, turn them off in the opposite direction - from destination backwards toward the source. This way, the “feeder” transients from the mixer and signal processor will never be amplified by the power amp and broadcast at high volume through your speakers.

Pink noise will provide an even distribution of power across all ISO frequency bands. Being able to visually display what is picked up by a good microphone allows you to determine the frequency characteristics of the room and is a tool to help identify trouble spots that EQ might help you improve. Of course there is no better tool than your ear, so you should use this as the final determining factor for good sound.
