26. Exposure to extremely high noise levels may cause permanent hearing loss.
Individuals vary considerably in susceptibility to noise-induced hearing loss,
but nearly everyone will lose some hearing if exposed to suciently intense
noise for a period of time. The U.S. Government’s Occupational Safety and Health
Administration (OSHA) has specified the permissible noise level exposures shown
in the following chart.
According to OSHA, any exposure in excess of these permissible limits could result
in some hearing loss. To ensure against potentially dangerous exposure to high sound
pressure levels, it is recommended that all persons exposed to equipment capable
of producing high sound pressure levels use hearing protectors while the equipment
is in operation. Ear plugs or protectors in the ear canals or over the ears must
be worn when operating the equipment in order to prevent permanent hearing loss
if exposure is in excess of the limits set forth here:

SRM-Flex is the perfect tool for singer-songwriters touring the local coee shops. Bring your favorite axe and mic,
SRM-Flex and cables and power cord. Do you have a special guest that joins you on keys on a few tracks? Have them
bring their keyboard, cables and power cord, as well!
In this example, a dynamic microphone is connected to the channel input of SRM-Flex. Note that the mic-line / Hi-Z switch
is set to “mic” (switch lef).
Now grab your axe and plug it directly into the channel 2 input. Or if you use eects, connect the guitar to the eects input
and another cable from the eects output to the channel 2 input. Note here that the mic-line / Hi-Z switch is set to “Hi-Z”
(switch right).
Your friend’s keyboard may be plugged directly into stereo inputs 3/4 using cables with /4" jacks. Lastly, a phone
may be connected via Bluetooth to stereo channel 5/6. The phone can be used as playback music between sets
and/or as backing tracks to your compositions!
Before wowing the crowd with your tunes, you will want to set a speaker mode, described in detail on page 3.
For this type of setup, live works well.

SRM-Flex is a really simple – yet very powerful – tool to use for presentations, karaoke and other similar situations.
Here we just attached two mics to channels and 2 of SRM-Flex. Note that the mic-line / Hi-Z switch is set to “mic”
(switch lef) on both channels.
Set the speaker mode to speech and deliver the great news to your company employees, to the board, stakeholders,
convention attendees, or whatever other presentation you can think of... the possibilities are endless!
Is there a post-speech karaoke-o? Or maybe there is no speech and you’re just having friends over on a Saturday
night for karaoke. Either way, keep the mics as they are, plugged into channels and 2, but also connect a phone
via Bluetooth to stereo channel 5/6. This phone has all of the karoke tracks. What song(s) will you sing?!
For karaoke, you will want to set the speaker mode to music. More information about speaker mode is described in detail
on page 3.

Perhaps you’re a DJ that’s been hired to work a wedding. Well, the SRM-Flex works great for playing bumpin’ tunes all night
to the happy newlyweds and raucous crowd that’s groovin’ and dancin’ to your fine selection.
In this example, a mic is connected to channel of SRM-Flex and the mic-line / Hi-Z switch is set to “mic” (switch lef).
This mic may be used for best man / maid of honor toasts, for the DJ to announce the couple’s first dance and any
“...someone with a blue truck, license plate XYZ23 lef their lights on...” announcements.
All the music is on a playlist on the DJ’s laptop. It’s connected directly to the /8" stereo channel 5/6 input.
The last connection is an XLR cable from the mix out jack of the first SRM-Flex to the channel input of an additional
SRM-Flex.
The speaker mode on both may be set to speech when toasts are happening and switched back to music when the dancing
begins!
Pro Tip: wrap each SRM-Flex with wedding garland so they blend in with the theme!
