Analyzer. With the RSA27 you have acquired the flexible and applied realtime spectrum analyzing tool and pink noise
generator, which can optimize stage monitor sound quality and reduce feedback problems.
The RSA 27 offers the simple and clear operation interface and excellent performance. It contains the four pushing-
buttons, each of them is equipped with the LED indicator; 28 bar LEDs display, through which, the RSA can react
readily on program materials, then you can find the specific feedback points easily; a input gain control and a MIC
input socket.
In order to get the best out of your RSA 27 Realtime Analyzer, please go through this manual carefully.

3. INPUT GAIN Control
Rotating this control will give you proper gain. The control is provided with two different indication rings, when
releasing the LINE switch (5), you should read the inside ring (10dB ~ 60dB) indication; otherwise, pressing the
switch allows you read the outside ring (-12dB ~ +12dB) indication.
