@DaveM-Here is the chart I was referring to for general accoustic frequencies per instrument. It will come in handy if your doing alot of audio work with bands and you want to make a surround mix.
Click here for accoustic frequencies
 

know exactly what your doing. It is my main line in video (music video). Your audio sounds clean but you may need to sweeten it. Sweetening sound means making the sound richer. You do this with your EQ. The easiest way is to do this quickly is to sweeten it with Q. That will bring up your bass and treble and leave your mids alone. most mics (that are designed for voice) will pick up mids nicely but the low and high are an after thought. That's OK, you can adjust your audio to make the guitar more moving. The flute's accoustic range can be wide. Try the preset heavy and see what it sounds like. If you want to get down to the nitty gritty with the music you can find out the dynamic ranges of the individual instruments and the pull them out with the EQ and place them in the sound matrix where you want. It's not to hard.
 

n audio this is hard, with so many connecti ons.... the real thing you really have to worry about for beginners isn't really the type of connector you plugging into. It should be the type of signal is being sent to the connection. For example a 1/4 inch with three connections showing (TRS/Tip Ring Sleeve) can be used for a mono balanced line signal for gear to gear connection, mono insert and output for an effects or processor and also for a stereo headphone feed, I've seen older gear use it as a stereo line out from projectors. All three will take the same plug. Once you start to think in terms of signal and not connectors your life gets easier.
A lot of pro gear will use a balanced line for a more robust transfer of signal with less noise, converting from balanced to unbalanced is OK when going over short distances like in a desktop system. If you have to push the singnal on longer runs a balanced line is preferable.
some of the basic signal terms are:
Line Level-a 1 volt peak to peak signal used to send signal from device to device. Consumer and Pro gear have slightly different levels.
Mic Level-a signal from a microphone to a device, its signal is much lower than a line level (millivolts) not used to send signal from device to device in general due to is low signal level is more fragile. Plugging a line level signal into a mic input will overdrive the circuitry and cause distortion.
Mono= one discreet signal
Stereo= two discreet signals one signal path, left and right in the consumer world.
Unbalanced= where the signal is transmitted over two wires one ground and one positive.
Balanced= where the signal is transmitted over three wires, one ground and two "positive". the two "positives" have the signal wave 180 out of phase with each other. once in the device the two are summed together and any difference between the two will leave "noise" which is then removed from the original signal.
BOTH Mic and Line signals can be EITHER balanced or unbalanced.
Some common connectors are:
1/4"(phone)= originally used for patch bays, hence the name from the days when phone operators used them to make connections, TRS are used for stereo headphones , Balanced line connections when there isn't room to mount a XLR connection. TS are used for mono line connections and Hi-z microphone connection, mono headphones and amplified speaker connections(100s of volts)
1/8"(mini)= used for stereo headphones, stereo line o0n computers and other places where a 1/4 would be too big, also used for stereo mic inputs on many consumer DV cameras
XLR(canon)= used for balance lo-Z mics and for balanced line
RCA(phono)= used for mono line levels and for digital stereo
Banna plug= a single connector for a single wire, two would be required to send a signal, used in audio and on test leads for meters(some what old skool nowdays)
I guess the big thing I'm trying to get to is don't confuse connectors with signals. If you match signal to signal then the connetor matters less and less. but this discussion of connections and signals would fill a book
 

 

am going to hazard a guess that what you are plugging into is not a speaker out. Especially since you were on a mic in on your camera. I believe most small PA amps usually have a unbalanced line out or this might be an effects send from the amp. In both cases it probably is unbalanced. If the cord you used gave you audio that was clean I would say continue using it and just give the line in on your camera a try. You'll get a little more headroom before clipping that way. If the audio sounded thin(low or no bass) you might have a problem with the cord. In this case it would be best to try a cord that has a tip/sleeve(mono) 1/4" on the amp end and a XLR with the tip wired to pin 2 of the XLR and the sleeve wired to pins 1 & 3 of the XLR. I see them at Markertek, just checked radio shack and the have one but the xlr is a female not male. Radio Shack doesn't carry as many audio goodies as they used to.
