THIS SWITCH IS OVERRIDDEN IF THE CONTOUR/BYPASS SWITCH (20) IS IN THE BYPASS MODE. THE ASSOCIATED LED (21) WILL REFLECT THIS CONDITION.
The Contour/Bypass switch (20) provides a flat response in the "Bypass" or “in” position. The "Contour" or “out” position allows the positions of the other two DynaQ™ switches to affect the tone. This switch overrides the other two switches in the DynaQ section, as the other two switches have no effect when in Bypass mode. When the Contour/Bypass switch is pushed in and is in Bypass mode, the LED (21) to the upper right glows Red. If either of the other two DynaQ switches (18,22) are engaged, the associated LED’s (19,23) go out to indicate that their function has been bypassed.
THE BASS ENHANCER/BYPASS SWITCH (22)
Provides a dynamic bass boost that is signal level dependant
When the "Bass Enhancer/Bypass" switch is pushed in, and the "Bass Enhancer" mode is engaged, the LED (23) to the upper right glows Green.
THIS SWITCH IS OVERRIDDEN IF THE CONTOUR/BYPASS SWITCH IS IN THE BYPASS MODE OR THE MUSIC/ SPEECH BUTTON IS IN THE SPEECH MODE. THE ASSOCIATED LED WILL REFLECT THIS CONDITION.
If full
Music/Speech switch (18): Music mode (button Out, LED dark)
Contour/Bypass switch (20): Contour mode (button Out, LED dark)
Bass Enhancer/Bypass switch (22): Bass Enhance mode (button In, LED lit green)
Then a single push of the Contour/Bypass switch (20) can restore the speaker to nominally flat response, while with the same starting point settings, a single push of the Music/Speech button (18) can provide a Speech contour with no
SLEEP SWITCH (24)
Located above the LINE OUT section, the Sleep switch (24) provides a means to disable the automatic power off Sleep feature so that the Impulse® 12D remains on at all times. The automatic power off Sleep feature is disabled when the switch is in the “out” position, it is engaged when the switch is in the “in” position, and the indicator LED (25) to the upper right of the switch will glow green.
When no signal is present at any of the inputs for approximately 16 minutes, the automatic power off Sleep function will shut the power off to most of the electronics in the Impulse® 12D. The unit will turn back on if a signal is applied, but it will take a few seconds for the Impulse® 12D to start producing sound. This is due to the
Note that when in Sleep mode, all LED’s on the rear panel will be dark. If the front logo LED switch (17) is in the Signal or Power position, the glowing front logo LED will indicate the unit's AC power status. If the front logo LED switch is in the “Off” position, there will be no indicator lights active when in Sleep mode.
LINE OUT SECTION (D)
Line Out is intended to link multiple Impulse® 12D’s in a line or to provide a feed to a powered subwoofer or other electronics that need to receive a full range version of the input signal. The connectors available are a
