How many SRM loudspeakers can be chained together using the THRU jacks?

The number of SRM450 loudspeakers that can be chained together at a time is limited only by the output impedance of the mixer or equipment that is directly feeding them.

To insure optimum signal transfer, the net input impedance of a group of SRM450 inputs (ZT) should be no less than 10 times the output impedance of the equipment acting as the signal source.

The net input impedance of a group of SRM450's can be found by donning a propeller-laden cap, and using the following simple formula: Where n = the number of SRM450's being chained together and ZT = the total input impedance in Ohms of the SRM450 chain.

For those of you with Mackie compact VLZ and VLZ PRO mixers, this means that you can chain up to sixteen SRM450's together without any problem; and if this isn't loud enough, then you should remove the earplugs before continuing.

Is it normal for the speaker to "pop" when it is switched on or off?

It is normal for the SRM to emit a slight "pop" when it is powered up or down. The pop is caused by electricity left inside the amplifier circuitry discharging to the speaker.

The speaker hums when I connect something to its input...

The presence of a 60Hz hum in the speaker only when a connection is made to another piece of equipment suggests the presence of a ground loop. Such a loop is caused by electrical interaction of the signal grounds on two pieces of equipment, and is not necessarily an indication of broken gear.

If a balanced connection to the SRM is being used, the simplest way to correct this problem is to lift the signal ground on the end of the connecting cable closest to the signal source.

NOTE: This is not to be confused with disconnecting the safety ground on the power plug - this should be avoided at all costs, as it can present a safety hazard. If an unbalanced connection is being made to the SRM, a line coupler such as the Ebtech Hum Eliminator can be used to eliminate the ground loop.

What happens if the Limit light is turning on?

When the Limit light is flashing or on, this means that the amplifier is being pushed a bit too hard. If you see this happening, turn down the level control immediately until the Limit stops lighting.

What is the proper method for flying or mounting the speaker?

Our engineers have designed the speaker with integrated fly points to simplify its integration into a permanent installation. Due to the inherent dangers involved in hanging or mounting these or any speakers, we strongly recommend that a qualified professional be employed in any such installation. The SRM550/650 accepts M-10x1.5x37mm eyebolts. SRM350 / 450 M – 10 x 1.5 x 20mm

Will the SRM350, 450, 550, 650 function as a floor monitor?

Absolutely!! In fact, you will probably have a hard time finding a floor monitor that sounds as good as this! The asymmetrical trapezoidal design of the box lets you set the speaker on its side giving the perfect tilt for a floor monitor -- without tipping over and making a hassle.
