Mackie SRM1801 Features
2. POWER
Press up on this switch to turn the SRM1801
subwoofer on. The power LED [11] above the LEVEL
knob [7] illuminates when the POWER switch is on and
AC power is available at the linecord socket.
Press the bottom of this switch to put the subwoofer
into standby mode. It will not function, but the circuits
are still live. To remove AC power, either turn off the
AC mains supply, or unplug the power cord from the
subwoofer and the AC mains supply.
As a general guide, powered
subwoofers should be turned on after the
mixer and other sources, but prior to full-
range speakers. Additionally, they should
also be powered off after the tops, but before the mixer
and other sources. This will reduce the possibility of any
turn-on, or turn-off thumps in your speakers.
The rear panel is where you connect AC power
and your signals to and from the subwoofer. You may
also adjust the level and polarity to match the other
loudspeakers in your system and account for the
subwoofer’s location and your room’s environment.
1. IEC AC Receptacle
Connect the detachable line cord to this IEC socket
securely, and plug the other end into an AC outlet.
Make sure the AC power is matched to the AC power
indicated on the rear panel above the IEC socket.
