2 - INPUT MIC / LINE:
Allows the selection of different input sensitivities to permit the connection of many
different sources, with or without the use of a mixer or external microphone preamplifier.
See "Setting Input Sensitivity" on page 23-24.
3 - LEVEL:
Sound level adjustment. With the input in the "MIC" position the level can be adjusted over a large
range. In the "LINE" position most typical applications will require that the level control is set at 12
o'clock. (More details are outlined in "Setting the Input Sensitivity" and "Setting the Gain").
6 - POWER SWITCH:
Turns the power on. The illuminated logo in the front of the speaker serves also as a
power "on" indicator.
7 - LINE SELECT:
Allows the user selection for different local voltage ratings.
8 - AC LINE INPUT:
Standard IEC AC mains input connector.
Indicators
4 - SIGNAL:
Signal indicator. The green LED illuminates when a signal is present.
5 - OVERLOAD*:
The red LED illuminates when the system overload protection is active. If the input signal is too
strong or the "LEVEL" control set too high, the red LED will illuminate constantly. Illumination of
the "OVERLOAD" LED can be avoided by reducing the input level or turning down the
"LEVEL" control to the point at which the red LED occasionally flickers.
Connectors
9 - XLR:
Female balanced XLR and 1/4 inch phone jack combo balanced input connector.
10 -XLR :
Male balanced XLR output connector. This connector provides a full-range signal which can be daisy
chained to another speaker.
