Connections from Mixer

XLR to XLR

(balanced to balanced) 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.

¼ Inch Tip-Ring to ¼ Inch Tip-Ring

(unbalanced to unbalanced) is fine: You could have difficulty if you are running long lines (and losing signal or picking up noise). If you are, consider using shorter cable runs, or running an balanced line. To do this you can use a short unbalanced cable to a DI (to convert from unbalanced to balanced) and run from there: XLR to XLR (balanced to balanced) to the Bose System.

XLR (balanced) to ¼ Inch Tip-Ring-Sleeve (balanced)

This doesn't do much for you. This is because the ¼ Inch input on the Bose System is Tip-Ring unbalanced anyway.

Other (not Mixer)

¼ Inch Tip-Ring-Sleeve balanced to XLR balanced

Specialized instrument cable (probably Guitar)

This is probably a specialty cable that was supplied with the instrument. It is intended for a microphone input on a mixer. This should work fine with the Bose System.

Female XLR to ¼ Inch Tip-Ring

Microphone adapter

This will probably not work very well. Sometimes you see these being used for home karaoke machines. These are not suitable for professional use. The ¼ Inch input was designed for high impedance line-level inputs and may not provide enough gain for a microphone which is probably low impedance.

¼ Inch Tip-Ring (unbalanced) to XLR (balanced)

Instrument adapter

This may not work particularly well. You are probably running an impedance mismatch (high impedance from the instrument to low impedance balanced XLR).
