5.5.1 Setting the clock
The date and time of the hardware clock is initially set in Eastern
Standard Time. After your PC is connected to the hardware,
check the clock and set it as necessary for the time zone and
region of your installation.
Adds a system Auto On/Off event
This event applies only to the whole system. You can select individual on or off times for the day(s) you choose. Or, you can
select on and off times in a single statement.
Programmer’s Note: One Auto On/Off event specifies
both an “On” time and an “Off” time and is counted as two
events.
To adjust the clock settings manually, click the Set Clock button
in the clock panel. The Clock Settings window opens, allowing
you to make adjustments to the date and time. Click Apply or OK
to set the clock in the hardware, or click Cancel to close the window and leave the clock settings unchanged.
Adds a zone Mute event
This event allows you to mute/unmute the zone output at a
specified time on selected days of the week.
5.5.2 Adding events
When you click the On/Off, Volume, Source, or Auto Volume
event button, an event of that type is added to the event list. At
this point you can change the event settings. When the event list
exceeds the length of the pane, the software will add a scroll bar
on the right side.
A maximum of 64 events may be added to a system. This means
that the total number of events from all event lists must not
exceed 64. An On-Off event consumes two events, while source
change, volume change, and Auto Volume events consume one
apiece. A counter is provided in the Schedule mode window to
keep track of the number of remaining events.
Adds a zone Volume Change event
This event allows you to change the volume level at a specified
time on selected days of the week.
Remaining events
counter
Programmer’s Note: The maximum/minimum volume
stops cannot be adjusted in this pane. To adjust these limit
stops, select the Output Gain function in the Set Up Hardware mode.
Zone events programmed to occur at the same time as a “System ON” event will not occur. To ensure that zone events will happen, they must be programmed to occur 15 minutes after the
“System ON” event. For example, if a “System ON” event is programmed to occur at 8:00 AM, the first zone event should be programmed to occur at 8:15 AM.
Installer’s Note: Flashing the Installer software configuration file to the E4 unit sets the default state of the system
when it is turned on. Whenever possible the default state of
the system should be set to meet the requirements most likely
to occur after a scheduled “System ON” event.

This event allows you to change the source at a specified time on
selected days of the week.
To view any event and change the settings, first click the system
or one of the zone tabs. Then select an event in the list to display
the event settings in the control pane. Now, you can edit the settings just as when an event is added.
5.5.4 Removing events from the list
To remove an event from the list, select the event by clicking on it
and then click the
(Remove Event) button.
Programmer’s Note: After changing any event settings
or removing an event from the list, you must flash the
hardware in order for the change to take effect.
Adds a zone Auto Volume event
This event allows you to turn Auto Volume on or off at a specified
time on selected days of the week.
Programmer’s Note: Do not schedule an Auto Volume
event on a zone that is not set up for Auto Volume.
Programmer’s Note: Events are only saved to the E4

6.0 E4 System Setup
Programmer’s Note: If you are using the E4 system to
drive speakers that are not Bose® products, choose the
No EQ setting or one of the four high-pass filter settings
at the end of the list.
The No EQ setting helps protect the E4 against loudspeaker transformer saturation when non-Bose loudspeakers are connected to
the E4 hardware. This setting acts as a band pass filter and allows
energy between 80 Hz and 16 kHz to be sent to the amplifier section of the E4 electronics.

If you change the speaker EQ type, any subzones will be automatically changed to the new Speaker EQ setting, and be given the
default loudspeaker tap. Depending on the quantity and tap of
speakers, you could receive an error message notifying you that the
system exceeds the 400 W limitation of the E4 system. If this problem occurs, delete the subzones from the subzone list. This will
allow you to change the speaker EQ type.
Subzones table – The Subzones table allows you to document
the speakers used in a zone.
A zone is a group of speakers that are driven by the same amplifier output channel. A subzone is a group of speakers within a
zone that use a common tap or are of a common type.
For example, you may have installed ten Model 16 speakers in a
dining room and set it up as a zone to be driven by channel 1. In
this zone you may have established two subzones, one with five
Model 16 speakers tapped at 8W and the other with five tapped
at 16W.

6.0 E4 System Setup
Input gain setup sequence
Input gain meter – The input gain meter indicates the average
input signal level of the hardware. The meter is divided into three
color segments:
1.
Set Opti-source® to Off. This allows you make the initial
gain setting.
2.
Select the source Type and determine if Mic Power +12V is
needed. Set Mic Power to On if required. Leave it in the Off
setting if you are using line inputs.
Amber = Low signal level
Start your input source and monitor its signal on the gain
signal level meter. If the level is green, go to step 4. If the
level is yellow, increase the input gain until the level is green.
Likewise, if the level is red, reduce the input gain until the
level is green.
Red = High signal level
3.
Green = Good signal level
Signal present indicator – The signal present indicator tells you
if a signal is being received by the hardware:
Inactive = No signal
Green = Good signal
Programmer’s Note: You may have to repeat step 3 a
few times if the input source is a CD player. The output
level of a CD player varies based on the program material.
4.
Set Opti-source to On. If you are using a source that
produces a varying output level due to program material,
such as a CD player, Opti-source leveling will compensate
for these variances. If your system will be switching among
multiple sources, Opti-source leveling will compensate for
variances among the different sources.
5.
Repeat steps 1 to 4 for the remaining system inputs.
Red = Signal clipping
Opti-source – This is the on/off control for this function. When
on, Opti-source leveling automatically manages the input gain
level so that the full output of the amplifier can be achieved. It
does this by adjusting the input signal level to obtain the desired
amplifier input signal level (+11 dBV). When setting the initial
input gain level, check to make sure that Opti-source is Off. If you
do not see this setting in the control pane, click on More to display the Opti-source On/Off boxes.
Programmer’s Note: The Opti-source state cannot be
changed when the Opti-voice® paging system is on.
When you turn Opti-source on, you should only hear a small
change in volume. If you hear a large increase, raise the input
gain. Likewise, if you hear a large decrease, lower the input gain.
Input gain controls

The following chart shows how Opti-source leveling operates.
For sources whose average input signal level is less than –20
dBV, Opti-source leveling will add 20 dB of gain. For sources
whose average signal level is between –20 and 0 dBV, Optisource leveling will add the necessary gain so that the average
output of the Opti-source function is +11 dBV. Sources whose
average level is greater than 0 dBV will have gain reduction
applied so that they maintain an average of +11 dBV at the Optisource leveling output.

Gain slider – Click and drag the gain slider up/down to set the
input gain. Changes in the slider's position are continuously sent
to the E4 hardware so you will hear the change in gain as it is
applied and see the change in the signal level on the meter. The
gain range is dependent on the Type setting: 80 dB for Mic; 70 dB
for Line.
Programmer’s Note: When setting up the system,
adjust the input gain slider until the meter is green.

Input Signal Level (dBV)
Input signals from –20 to 0 dBV fall within the ideal operating
range for the Opti-source leveling function. This is reflected in the
color scale used for the input gain signal level meter. If your input
signal level is within the green area of –20 to 0 dBV, Opti-source
leveling will effectively manage the input source level.

Auto Volume setup procedure
Programmer’s Note: While the Auto Volume calibration is running,
• Make sure that the system hardware installation is complete
and that all components (sense microphones, speakers, and
Auto Volume user interfaces) are properly connected. Remember that speakers must be directly wired to the ZONE OUT
connectors on the E4 rear panel.

4.
Click Set Up to start the Auto Volume Setup process. The
initial Auto Volume Setup dialog appears in the window.
• Make sure that you have selected the correct speaker model in
the ZONE setup pane.
• Make sure that the output gain is set so that the source can be
heard without dropping out.
• Check that sources have been assigned to zones.
Programmer’s Note: If a source is routed to multiple
zones, you need to perform Auto Volume calibration on
that source only once. After calibration, the source is
“locked” (no adjustments to the source will be allowed)
until all zones using that source have been reset.
• Check the EQ pane and make any final adjustments.
• DO NOT USE AUTOTRANSFORMERS: Speakers must be
directly wired to the ZONE OUT connector of the E4 hardware.
DO NOT use an autotransformer on the speaker line to adjust
the speaker volume. If you lower the volume using an
autotransformer, the E4 system will raise the volume. Likewise,
if you raise the volume using an autotransformer, the E4 system will lower the volume.

Wait for the setup steps to be completed.
Programmer’s Note: If you attempt to calibrate a
source that is already calibrated, the dialog box will tell
you that source calibration is being skipped.
When the setup steps are done, you are asked to make volume adjustments. The maximum output gain should always
be greater than -20 dB for proper Auto Volume operation. If
the maximum output is less than -20, the source calibration
procedure might fail. If your system is too loud in this range,
change the speaker taps to a lower setting.

The source calibration process takes about three minutes
per source. For each source, the input gain is measured and
optimized, and the source level is activated. When this is
done, the software displays the following confirmation.

Resetting a calibrated Auto Volume zone
To cancel the calibration in an Auto Volume zone, click the Reset
button. The Reset button is available only after a zone is successfully calibrated.
When you reset a calibrated Auto Volume zone, the keypad control programming is restored to that of a Standard Wall Plate the
next time you perform a hardware flash.
Programmer’s Note: Be sure you want to reset the
zone before you click the Reset button. If you reset the
zone, you will need to run the Auto Volume setup process
again before you can use Auto Volume.
