SRM-Flex: Top Panel Features

3. Power LED

This LED will illuminate green when the SRM-Flex
is turned on, as a reminder of how on it really is.
If it is not on, then it is off, and it becomes a rather
nice weight for keeping your morning newspaper
from blowing away in the wind.
If it does not turn on, make sure the power cord
is correctly inserted at both ends, the local AC mains
supply is active, and the power switch is on.
There is a horizontal LED bar located
near the bottom of the base station /
subwoofer, as well as near the top
of the high frequency driver column.
These, too, will illuminate green when powered up.
However, they may be turned off or set to show signal
via the SRM-Flex Connect App. Read the reference
guide for more information.

4. XLR and 1/4" Combo Inputs [Chs. 1 and 2]

Input channels 1 and 2 may accept a balanced
mic signal using an XLR connector. They are wired
as follows, according to standards specified by
the AES (Audio Engineering Society).
XLR Balanced Wiring:
Pin 1 = Shield (ground)
Pin 2 = Positive (+ or hot)
Pin 3 = Negative (– or cold)
In addition to accepting a balanced mic signal
using an XLR connector, these input channels may
also accept 1/4" line-level signals driven by balanced
or unbalanced sources.
Also, both channels may accept a Hi-Z source
(such as a guitar) via the 1/4" input without
the need for a separate DI box. Be sure to set
the Mic / Hi-Z switch to the right, though!

To connect balanced lines to these inputs, use
a 1/4" Tip-Ring-Sleeve (TRS) plug. "TRS" stands
for Tip-Ring-Sleeve, the three connection points
available on a stereo 1/4" or balanced phone jack
or plug. TRS jacks and plugs are used for balanced
signals and are wired as follows:
1/4" TRS Balanced Mono Wiring:
Sleeve = Shield
Tip = Hot (+)
Ring = Cold (–)
RING
To connect unbalanced lines to these inputs,
use a 1/4" mono (TS) phone plug, wired as follows:
1/4" TS Unbalanced Mono Wiring:
Sleeve = Shield
Tip = Hot (+)
NEVER connect the output of an amplifier
directly to an input jack. This could damage
the input circuitry!
