In the discussion that follows, we are talking about mixer out to Bose System Channel 1 or 2.XLR to XLR
should be fine
unless you are having problems, but you should be able to solve that by turning down the output from the Mixer. Keep reading - more in three paragraphs.¼" Tip-Ring to ¼" Tip-Ring
unless you are running long lines or picking up noiseXLR (balanced) to ¼" Tip-Ring-Sleeve (balanced)
doesn't do much for you
because the ¼" input on the Bose System is Tip-Ring unbalanced anyway.
So if you Kev are running XLR (from the mixer) to XLR (Bose System), you should be fine.
Things you can do if the signal is too hot (you are having trouble with the input clipping on the Bose System)...
- check to see if there is a 'pad' built-in on the mixer (most Mackie mixers have this on the panel beside the XLR outs)
- turn down the main outs on the mixer
- use a 20 dB pad (attenuator) between the mixer and the Bose System.
For anybody who is still reading.¼" Tip-Ring-Sleeve balanced to XLR balanced
Specialized instrument cable (probably Guitar)
This is probably a specialty cable that was supplied with the instrument, and intended for a microphone input on a mixer. This should work fine with the Bose System.Female XLR to ¼" Tip-Sleeve
will probably not work very well.
The ¼" input was designed for high impedance line-level inputs and may not provide enough gain for a microphone which is probably low impedance. ¼" Tip-Sleeve (unbalanced) to XLR (balanced)
may not work particularly well
You are probably running an impedance mismatch (high impedance from the instrument to low impedance balanced XLR).
