10. Volume Knobs

The endless rotary volume knobs adjust the channel's
relative volume to the master bus. This allows signals
from the outside world to be adjusted to run through
each channel at optimal internal operating levels.
The main meters will display the input signal level
(for that channel) as the knob is turned. The main
meters will display the output level 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 input
level past max – there is no "beyond max".
It also will not wrap around back to off and vice-versa.
• Channels 1-4: – dB (off) to +16.0 dB (max)
• Bluetooth: – dB (off) to +10.0 dB (max)
These knobs also act like momentary switches
with three possibilities:
• Push down and release to see the current input level.
• Push down and release three times quickly to zero
out the current input level.
• Push down and hold for two seconds to see the peak
input level.

11. Reverb Send Knobs [Chs. 1 and 2]

These endless rotary reverb send knobs allow
you to select the amount of reverb you would like
to add per channel.
The main meters will display the reverb level (for that
channel) as the knob is turned. The main meters will
display the output level 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 reverb
level past max – there is no "beyond max".
It also will not wrap around back to off and vice-versa.

These knobs also act like momentary switches
with two possibilities:
• Push down and release to see the current reverb
level.
• Push down and release three times quickly to zero
out the current reverb level.
Don't hear any reverb? Make sure
it's turned on either via the SRM-Flex
or SRM-Flex Connect app.
Channel Equalization (EQ)
Channels 1 and 2 have 2-band EQ with shelving hi
— low shelving at 90 Hz and high
and shelving low
shelving at 6.0 kHz. "Shelving" means that the
circuitry boosts or cuts all frequencies past the
specified frequency. For example, maxing the low EQ
to 5 dB boosts bass starting at 90 Hz and continuing
down to the lowest note you never heard and 6.0 kHz
on up boosts the treble in the case of the high EQ
With too much EQ, you can really upset
things. We've designed a lot of boost and cut
into the equalizer circuit because we know
that everyone will occasionally need that. But if you
max the EQ, you'll likely get mix mush. Equalize subtly
and use cut as well as boost. If you find yourself repeat-
edly using a lot of boost or cut, consider altering the
sound source, such as placing a mic differently,
19
trying a different kind of mic, a different vocalist,
changing the strings, or gargling.

12 and 13. Low and Hi EQ Knobs [Chs. 1 and 2]

These endless rotary EQ knobs allow you to boost
and cut EQ to channels 1 and 2.
The main meters will display the EQ boost / cut
(for that channel) as the knob is turned, with the
center LED being 0 dB (flat). The main meters will
display the output level 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 EQ levels past max – there is no
"beyond max". It also will not wrap around back
to –15 dB and vice-versa.
• Low EQ: –15 dB (cut) to +5 dB (boost) at 90 Hz
This frequency represents the punch in bass drums,
bass guitar, fat synth patches, and some really serious
male singers who eat raw beef for breakfast.
• Hi EQ: –15 dB (cut) to +5 dB (boost) at 6 kHz
Use it to add sizzle to cymbals, an overall sense
of transparency, or an edge to keyboards, vocals,
guitar and bacon frying. Turn it down a little
to reduce sibilance or to mask tape hiss.
