For microphone connections, you can
daisy-chain up to two SRM450v2s using the THRU
jacks as shown.
Take great care to point any microphones

SRM450v2: USING A MICROPHONE AND THE THRU JACK
The SRM450v2 may be
paired with a Mackie SRM1801
subwoofer to create an
incredibly powerful system.
The active crossover inside
the SRM1801 splits the full-
range input signal into two
ranges. The SRM1801 plays the
low-frequency range and sends
the high-pass range to the
SRM450v2.
The SRM450v2 can be pole
mounted on top of the SRM1801
as shown using the optional
SPM200 Speaker Pole Mount,
saving the cost of a more
expensive tripod stand.
