17.  Master Volume Knob

The endless rotary master volume knob allows  

you to adjust the overall output level. This gives  

you the ultimate feeling of power and control over  

the sound level sent to your audience. Adjust this  

control carefully, with your good eye on the meters  

to check against overloading, and your good ear  

to the levels to make sure your audience (if any)  

is happy.

The main meters will display the output signal level  

as the knob is turned and return to bouncing meters 

after five seconds of inactivity.

While the knobs may rotate endlessly, 

there are high and low parameters. In other 

words, you can’t keep cranking the output 

level past max – there is no “beyond max”. 

It also will not wrap around back to off and vice-versa.
•   Output Level:  –  dB (off) to +10.0 dB (max)

This knob also acts like a momentary switch  

with three possibilities:
•   Push down and release to see the current output 

level. 

•   Push down and release three times quickly to zero  

out the current output level (thereby killing the sound)! 

•   Push down and hold for two seconds to switch  

between bouncing meters (peak meter mode)  

and a solid bar (volume level).

18.  Main Meters

These meters are made up of a single horizontal  

row of 17 green LEDs and are used to gauge the input 

and output levels, as well as display the reverb send 

levels and EQ boost / cut.

You can get a good mix with peaks flashing anywhere 

shy of the far right 3-4 LED bars. SRM-Flex will sound 

muddy and distorted if all meter LEDs are illuminated 

constantly. Turn down the master volume knob.

Remember, audio meters are just tools to help assure 

you that your levels are “in the ballpark.” You don’t have 

to stare at them (unless you want to).

19.  Limiter LED

SRM-Flex has a built-in limiter that helps to prevent 

the amplifier outputs from clipping or overdriving  

the transducers. The limiter indicator illuminates red 

when the limiter is activated. It’s okay for it to blink  

red occasionally, but if it blinks frequently or lights 

continuously, turn down the volume knob(s) until  

it only blinks occasionally.

Excessive limiting may lead to overheating, 

which in turn trips the thermal protect  

circuitry and interrupts the performance.  

See ‘Thermal Protection’ on the next page for more  

information.

20.  Mix Out

This is a balanced male XLR-type connector that  

produces a mono-summed post-DSP mix – after  

channel EQ and reverb, but pre-main fader, speaker  

EQ and limiting – from all input jacks. Use it to connect 

a Mackie loudspeaker off of the same signal source.

It is wired as follows, according to standards  

specified by the AES (Audio Engineering Society):
Balanced XLR Output Connector
Pin 1 – Shield (ground) 

Pin 2 – Positive (+ or hot) 

Pin 3 – Negative (– or cold)
