FAQs

The SRM1801 has its own crossover built in for the signal coming in and out. So go ahead and give it full range signal, it will take it from there.

The SRM1850 features a variable crossover that gives you even more control over your sound.

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 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.

The High-Pass outputs are perfect when using full range speakers along with the SRM subwoofers. What it does is basically sends back out the audio that you are putting into it but subtracts a lot of the low end. The reason for this is since you have the SRM subwoofer taking care of your low end, your full range speakers don't need to worry about it, so by connecting them to the high-pass outputs, they will be able to perform their duty of reinforcing the midrange and high frequencies much better and under much less stress.

With the SRM1850, you can choose which frequency you want to star to roll off the lows on your High Pass outputs. There are also preset levels that will match the SRM1850 perfectly with either the SRM550 or SRM650.

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.
