CONNECTING THE SYSTEM
Your MiniRay™Active Line Array system is designed to run as a simple full-range audio
solution with no need for any outboard processing. Simply connect XLR cables from the
output of your mixing console to the input of the MiniRay speakers, then daisy-chain to
the next ones. The Output (2) delivers full-range audio to all downstream speakers. The
active amplifiers contain their own respective active crossover networks with either a
High-Pass Filter (MR652) or Variable Low-Pass Filter (MR12). For extra control of the sound
you may use an outboard active 2-way crossover and connect LF output to the MR12s and
HF to the MR652s. When used as a full-range system, engage the High-Pass Filter (4) on the
MR652s and adjust the Low Pass Filter (4) on the MR12s to your liking.
Connecting for Full-Range Operation
Perform the following steps to connect the system for Full-Range operation using the
internal filters:
1. Ensure that all equipment to be connected is powered off and unplugged before
making any connections.
2. Using an XLR or 1/4" TRS cable (not included), connect one end to the output of
your mixer, then connect the other end to the Input (1) on the first MR652 speaker
in the chain.
3. Using the included XLR Jumper Cable, plug one end into the Output (2) on the first
MR652 speaker, then plug the other end into the Input (1) on the next MR652
speaker or MR12 subwoofer in the chain. Repeat until all speakers and subwoofers
are connected.
4. Using the included AC Power Cord, plug the NAC3FCA end into the power Input (5)
connector on one of the speakers or subwoofers. Do not plug it into a power outlet
yet.
5. Either repeat step 4 for each speaker and subwoofer or, using the included AC
Jumper, plug one end into the Output (6) on the first speaker or subwoofer, then
into the Input (5) on the next speaker or subwoofer in the chain. You can connect

14
up to 1x MR12 subwoofer and 4x MR652 speakers or 6x MR652 speakers in a single
power chain.
6. Repeat steps 4 and 5 until each MR652 speaker and MR12 subwoofer has a power
connection.
7. Ensure that the AC Power (7) switch on each MR652 speaker and MR12 subwoofer is
in the OFF position and that the Volume (3) knob is fully counterclockwise
(minimum).
8. Enable the High-Pass Filter (4) switch on each MR652 speaker, then set the Variable
Low-Pass Filter (4) knob on each MR12 subwoofer to the mid position.
