Frequently Asked Questions

The SRM 1550 uses a standard 3 prong IEC cable.

Is the power supply universal?

The SRM 1550 offers two XLR-F connections for inputs A and B. Each input has both a High Pass output 
and Full Range output. All 4 output connections are male XLR.

What connections does the SRM 1550 have?

The High-Pass outputs are perfect when using full range speakers with the SRM 1550. They send the  
audio signal out after going through a filter that subtracts a determined amount of the low end. Then 
your full range speakers can better reinforce the midrange and high frequencies while the SRM 1550 
takes care of the rest.
With the SRM 1550, variable mode lets you choose the cutoff frequency you want to use to roll off the 
lows to the High Pass outputs. There are also preset levels that will perfectly configure the SRM 1550 
for use with either the SRM 350 or SRM 450.

What are the High Pass outputs used for?
