SPEAKER OUT
The AC601/AC101 can be connected to one or two speaker cabinets. The high-quality Neutrik SPEAKON COMBO jack (23) accepts either a SPEAKON or a ¼"
speaker cable, and the second SPEAKER JACK (22) accepts only ¼" cables. Do not use instrument cables.
The AC601/AC101 delivers 150W of power into an 8 ohm cabinet, or 250W into a 4 ohm cabinet.
By default, the AC601/AC101 head is connected to the speaker cabinet housed in the combo. However, you can either connect the head to a separate,
external cabinet (unplug the ¼" cable from the speaker out jack, and replace it by a speaker cable that you connect to the external cabinet), or you
can use both the internal cabinet and an external cabinet by using both speaker jacks.
LINE OUT
This balanced XLR (24) output sends a balanced signal to the mixing console or snake in live and studio situations. The line out signal is pre-EQ and
pre-filters (which means that the signal that you send to the sound engineer is not affected by your EQ and filter settings), but can be easily
modified by a qualified technician to be post-EQ if desired.
GROUND LIFT
Occasionally when you're playing live and using the LINE OUT (24), the soundman will detect a hum from your amp's signal. This is almost always due
to a grounding problem related to your power source; you will likely eliminate this hum simply by flipping the GROUND LIFT (26) switch.
