peaker features
1. MASTER VOLUME CONTROL - controls the overall volume of the SPK 024 as well as the LINE OUT (11)
connector.
2. TONE - this is a variable frequency high-cut tone control that is primarily used to reduce high frequency
feedback. The control is essentially flat when turned fully clockwise and reduces more high frequencies as it is
rotated counterclockwise.
3. LED - displays the power state of the speaker. See A2 for details.
4. MIC INPUT - plug a wired dynamic microphone in here. This 1/4 inch jack is designed to accept a low
impedance microphone. The input volume is controlled by the MICROPHONE LEVEL knob (6). This input
does not supply phantom power.
5. OFF/AUTO/ON switch - this controls the power for the speaker after the MASTER AC SWITCH (10) is
placed in the ON position. The speaker is essentially OFF with this switch in the OFF position. The front panel
LED (3) will glow Red. The speaker will come ON from its standby mode automatically when any audio signal
is sensed when the switch is in the AUTO position. The LED (3) will turn from Red to Green. 10 minutes after
all audio stops the speaker will return to its standby mode and the LED (3) will return to Red. The speaker is ON
at all times when the switch is in the ON position. The LED (3) will glow Green.
6. MIC LEVEL - this knob controls the input volume of the microphone plugged into the MIC INPUT (4). It is
always good practice to leave the control turned all the way down (full counterclockwise) when no microphone
is being used.
7. LINE LEVEL - this knob controls the input volume of anything plugged into the LINE IN (8) jack.
8. LINE IN - this mono RCA jack is designed to accept audio from devices such as CD players, video tape players
or anything else with a line-level audio output. The input volume is controlled by the LINE LEVEL knob (7).
9. LINE OUT - this mono RCA jack provides line-level audio to drive additional speakers or other audio devices
with a line-level input. The level is controlled by the MASTER VOLUME CONTROL (1) on the front panel. If
this output is used to drive the LINE IN (8) of a second SPK 024, the MASTER VOLUME CONTROL (1) will
control the overall volume of both speakers.
10. MASTER AC SWITCH - controls overall power to SPK 024 speaker.
11. AC JACK - this is where the removable AC plug is attached to the speaker. The AC plug is polarized and will
only attach one way.
12. AC FUSE - the replaceable AC fuse is housed here. Follow the marking on the panel for proper replacement if
needed (0.5A for 210-240VAC use or 1.0A for 110-125VAC use).
13. AC VOLTAGE SELECTOR - set down when used with 110-125VAC (US and other areas) and up when used
with 210-240VAC (Europe and other areas). Be sure to check your local voltage before adjusting the selector.
The speaker is shipped from the factory set in the 110-125VAC position and with a cable designed for that
voltage. Note: The supplied AC cable is to be used for 110-125VAC only.
