:The easiest way to 'get through the gig' is to simply remove the top section and play through the bottom only. To balance out your sound in this mode, plug a cable into the 'bass line out' (don't connect it to anything).

:by removing the top half the L1 speaker the impedance effectively doubles for this section thus reducing the power output of the mid-highs and the bass will be more pronounced. By inserting a cable into the "bass line out" the power stand will "believe" that a PackLite has been connected and it will reduce the bass output level and the sound will now be "balanced".

; Classic

NOTE: The impedance issue affects the {{Model I}} and {{Model II}}. The {{Classic}} uses separate amplifiers for the top and bottom sections of the {{L1 CR}}. So the rationale for using a cable (or just a connector) into the bass line out may be different, it is still worth considering. You may also get decent results using the R1 Remote or {{T1}} to turn down the bass output.

Question:Mike: Is it safe to assume that getting the 1/2 pole raised to approximately ear level will help?

Question: Mike: Is it safe to assume that getting the 1/2 pole raised to approximately ear level will help?

Answer: Yes. Ideally, this is best. You need a sturdy flat surface to set the unit onto. A sturdy square bar table works.
