CONNECTIONSPLACEMENT

The S410s has two connectors labeled INPUT and THRU. These are both Neutrik Speakon™ connectors, which provide a secure and reliable connection for loudspeakers and subwoofers. These connectors are wired in parallel, and allow for connecting the input signal to another speaker’s input.

NEVER connect more than one output from a power amplifier to the S410s INPUT or THRU connectors.

Keep in mind, when connecting two or more speakers in parallel using the “thru” connections, that you want to avoid going below the minimum impedance requirements for your power amplifier.

The S410s has a nominal impedance of 8 ohms.
Two 8 ohm cabinets in parallel equals 4 ohms.
Three 8 ohm cabinets in parallel equals 2.7 ohms.
Four 8 ohm cabinets in parallel equals 2 ohms.

Use high-quality speaker cable as recommended by the power amplifier manufacturer.

DO NOT use coaxial shielded cable like a guitar cord to make speaker connections. They are not designed to handle the high currents required to drive a loudspeaker.

The Speakon connector is wired as follows: Pin 1+ = Signal (“+” or hot)
Pin 1– = Ground (“–” or cold)

The S410s subwoofer is designed to sit on the floor or stage. A socket is provided on the top of the cabinet for mounting another speaker on top of the S410s, like the Mackie S408 two-way loudspeaker. Use the optional Mackie speaker mounting pole (SPM100) to mount them on the S410s (see Hookup Diagrams on page 5).

WARNING: The cabinet has no rigging points and is not suitable for rigging. NEVER attempt to suspend the S410s by its handles.

As with any powered components, protect them from moisture. If you are setting them up outdoors, make sure they are under cover if you expect rain.

Room Acoustics

The S410s subwoofers are designed to sound as neutral as possible; that is, to reproduce the input signal as accurately as possible.

Room acoustics play a crucial role in the overall performance of a sound system. Here are some additional placement tips to help overcome some typical room problems that might arise:

• Avoid placing loudspeakers in the corners of a
room. This increases the low frequency output and
can cause the sound to be muddy and indistinct.
• Avoid placing loudspeakers against a wall. This, too,
increases the low frequency output, though not as

much as corner placement. However, if you do need

to reinforce the low frequencies, this is a good way
to do it.
• Avoid placing the speakers directly on a hollow
stage floor. A hollow stage can resonate at certain
frequencies, causing peaks and dips in the fre-

quency response of the room. It’s better to place the
