What is a Source? This is a line-level input signal such as pro-
grammed music, CD player, VCR/DVD, satellite feed, tape player,
radio, message repeater, or juke box. These sources are then
equalized, dynamically controlled, and routed by your selections
and priorities on the Soundzone Controller.
What is a Zone? This is the area where you wish the signal to
end up. The Z21S/Z32S outputs a stereo or mono signal to your
chosen Zone. Built-in subwoofer crossovers allow you to include a
subwoofer in that Zone. This allows you to attain the wide band-
width sound your patrons are used to hearing.
What is a good volume? Determining a good volume is a balance
of art and science. You need maximum coverage without interfer-
ing with the workplace environment or customer comfort and com-
munication. The Z21S/Z32S give you the tools you need in the
form of AutoWarmth™ and LevelGuard™ to get the best sound
quality from the volume that each application requires. Once you
have set your volume preferences, AutoWarmth™ and
LevelGuard™ help you keep it that way.
What is AutoWarmth™? In its simplest terms JBL's AutoWarmth™
can be thought of as being similar to the “loudness” control on a
home stereo, except it’s actual functions are considerably more
complex. AutoWarmth™ operates on a variable basis and auto-
matically makes the proper adjustments to maintain an even tonal
perception. This circuitry constantly adjusts for the ear's tendency
to hear less low frequencies at low volumes, and more low fre-
quencies at high volumes. AutoWarmth™ automatically ensures
full music fidelity at all volumes.
What is LevelGuard™? The LevelGuard™ circuitry helps keep
the volumes of various sources consistent by sensing the level of
the incoming audio source and automatically compressing the sig-
nal to a user selected preference.
