SAFETY INFORMATION
1. Parts that have special safety characteristics are identified by the symbol on schematics
or by special notes on the parts list. Use only replacement parts that have critical characteristics
recommended by the manufacturer.
2. Make leakage current or resistance measurements to determine that exposed parts are
acceptably insulated from the supply circuit before returning the unit to the customer.
Use the following checks to perform these measurements:
A. Leakage Current Hot Check-With the unit completely reassembled, plug the AC line cord
directly into a 120V AC outlet. (Do not use an isolation transformer during this test.) Use a
leakage current tester or a metering system that complies with American National Standards
Institute (ANSI) C101.1 "Leakage Current for Appliances" and Underwriters Laboratories (UL)
UL6500 / UL60065 / IEC 60065 paragraph 9.1.1. With the unit AC switch first in the ON position
and then in OFF position, measure from a known earth ground (metal waterpipe, conduit, etc.)
to all exposed metal parts of the unit (antennas, handle bracket, metal cabinet, screwheads,
metallic overlays, control shafts, etc.), especially any exposed metal parts that offer an electrical
return path to the chassis. Any current measured must not exceed 0.5 milliamp. Reverse the
unit power cord plug in the outlet and repeat test. ANY MEASUREMENTS NOT WITHIN THE
LIMITS SPECIFIED HEREIN INDICATE A POTENTIAL SHOCK HAZARD THAT MUST BE
ELIMINATED BEFORE RETURNING THE UNIT TO THE CUSTOMER.
B. Insulation Resistance Test Cold Check-(1) Unplug the power supply and connect a jumper
wire between the two prongs of the plug. (2) Turn on the power switch of the unit. (3) Measure
the resistance with an ohmmeter between the jumpered AC plug and each exposed metallic
cabinet part on the unit. When testing 3 wire products, the resistance measured to the product
enclosure should be between 2 and infinite MOhms. Also, the resistance measured to exposed
input/output connectors should be between 4 and infinite MOhms. When testing 2 wire products, the resistance measured to exposed input/output connectors should be between 4 and
infinite MOhms. If it is not within the limits specified, there is the possibility of a shock hazard,
and the unit must be repaired and rechecked before it is returned to the customer.
CAUTION: The Bose® E4 Series II Business Music System contains no
user-serviceable parts. To prevent warranty infractions,
refer servicing to warranty service stations or factory service.

PRODUCT DESCRIPTION
E-4 Series II Business Music System
The Bose® FreeSpace® E-4 Series II Business Music System is an integrated four-channel
digital signal processor and 400-Watt power amplifier for 70/100V business music applications.
The E-4 chassis provides a total of four source inputs (two Line In, one Mic/Line and one Mic/
Line/Page) to meet the needs of most business music installations. A Music on Hold (MOH)
output is also provided for simple integration into a phone system.
As a single component, the chassis provides all of the processing and control features required
for one to four zone business music applications. These features include:
• Auto Volume: When used with the optional FreeSpace Auto Volume Sense Mic, the E-4
system dynamically controls the program level in each zone so that the audio program
material can always be heard, regardless of the background noise.
• Scheduling: Allows you to program the E-4 system for automated on/off and source
selections according to time of day or day of week.
• Opti-Voice® Paging: Provides the appropriate sound level regardless of variations in
speech projection.
• Source Leveling: Automatically compensates for variations in source input levels.
• Dynamic Equalization: Maintains tonal balance at all listening levels.
• Room Equalization: Provides easy adjustment of tonal balance in each zone.
• Limiting: Protects loudspeakers from unwanted transient power loads.
• Signal Router: Meets the demands of most four-zone systems, allowing for any input signal
to be routed to any of the amplifier outputs.
• RS-232 Connection: Provides easy interfacing to your PC.
• Contact Closure Input: Allows remote power sequencing.
The integrated 400-Watt power amplifier features a patented power-sharing technology which
allocates power to each output.
For example, if you have a two-zone system that requires 5 Watts in zone 1 and 395 Watts in
zone 2, the FreeSpace E-4 Series II system distributes the power based on those needs.
The E-4 Series II also includes an easy-to-replace memory module, which holds a design file
and the current hardware configuration.

Hardware configuration
The system hardware version numbers
appear at the top of the Error Log listing.
These are the version numbers of the
software installed in the hardware at the time
of manufacture. These version numbers do
not pertain to the Installer™ software installed on your PC.
Power-on self-test results
The power-on-self test (POST) results are
only displayed when an error has occurred.
The POST test checks the basic operation of
the E4 Series II hardware to determine if it is
capable of properly performing audio processing and amplification. During the POST
test, six major components of the hardware
are tested.
• Host controller – The host controller monitors and controls the operation of the system
hardware. A host controller failure will cause
the message, “Power-on self-test incomplete” to appear in the host controller test
section. The failure type for a host controller
is an SRAM address failure.
• Flash memory test – The flash memory
contains the configuration, design file, and
system event schedule. A flash failure will
cause the message, “Power-on self test
incomplete” to appear in the host controller
flash test section.
• Peripheral controller – The peripheral
controller monitors contact closures, front
panel connections and user interface connections for incoming event messages. Any
failures in these areas will cause the message, “Power-on self-test incomplete” to
appear in the peripheral controller flash test
section. If a user interface failure occurs,
check the user interface wiring for shorts.
• DSP test – The DSP performs all signal
processing and routing functions.
• Upper and lower amplifier test – The upper
and lower amplifier test determines if the
amplifiers are operating properly. An amplifier failure will cause the message, “Poweron self-test incomplete” to appear in the
upper or lower amplifier section of the POST
test results. Additional details on the exact
cause of an amplifier failure can be found in
the amplifier section of the Error Log.
• Front panel board test – The front panel
board test deter-mines if the USB port is
working properly. A USB failure will cause
the message, “Power-on self-test incomplete” to appear in this section of the POST
results.
Note: The USB port is not currently used for
communication with the E4. If a USB failure
occurs, the E4 will still function normally for
audio processing and amplification.

TROUBLESHOOTING
Amplifier alarms
Each amplifier section monitors its own
operation and performance. If a fault condition occurs, it is reported in the Amplifier
Alarm section of the Error Log. Upper amplifier alarms affect channels 1 and 2, and
Lower amplifier alarms affect channels 3
and 4.
The amplifier section of the alarm log indicates the following:
• Alarm type – The generated alarm type is
the first item.
• Amplifier status – When an alarm is
generated, the amplifier reports its current
operating status for diagnostic purposes.
The following items are reported in the
status:
Date & Time: Date and time when alarm
condition occurred.
Rail Voltage: The amplifier positive and
negative rail voltages. Normally, the amplifier
rail voltage should be between 100V and
190V. Voltages outside this range will cause
the amplifier to shut down. In the 70V mode,
a normal rail voltage is approximately 125V.
In the 100V mode, a normal rail voltage is
approximately 165V.
Temperature: The internal operating temperature of the amplifier. Normally, this will
be between 0° and 160° Fahrenheit (-18° to
71° Celsius).
Output Voltage: The actual output voltage of
the amplifier at the time of the alarm.
Output Current: The actual output current of
the amplifier at the time of the alarm.
Input Status: The status of the input signal to
the amplifier. Possible status messages are
DC sense fault, amplifier module fault, AC
power fault, sleep mode, high-frequency
sense fault, and retry fault.
Output Status: The status of the amplifier
output at the time of the alarm. Possible
status messages are “amplifier module
muted,” and “speaker relay off.”
Fan Speed: The fan speed at the time of the
alarm.
Operating Mode: The current setting of the
output voltage select switch, 70V or 100V.
Amplifier alarms – using output voltage and
current
Reviewing the output voltage and current
can help to diagnose a problem. Compare
the output voltage and current for each of
the two amplifier outputs to determine the
nature of the problem.

Amplifier alarms – using rail voltage
Normally, the amplifier rail voltage should be
between 100V and 190V. In the 70V mode a
normal rail voltage is approximately 125V. In
the 100V mode a normal rail voltage is
approximately 165V.
By comparing the + and – rail voltages, you
can determine if you are driving an impedance which is too low (<12 Ohms). In this
case the difference between the two rails will
probably be greater than 20%. If one of the
rails shows a voltage, and the other does
not, the amplifier module should be replaced.
As you review all alarm records you can
compare the plus rail voltage in each of the
status sections. For example, a drop of 50%
in one status could indicate a brownout
condition occurred.
85
TROUBLESHOOTING
Amplifier alarms – input and output
status
The Input and Output Status sections display
the fault condition which caused the alarm
and the current status of the amplifier output.
A number of fault conditions can be displayed in the Input Status section:
DC Sense Fault: A power supply fuse, output
FET, amplifier module, or some combination
of the above has blown. The amplifier module should be replaced.
Amplifier Module Fault: When the Amplifier
Module fault occurs by itself it can be caused
by any of the following:
• Shorted loudspeaker line – Check the
loudspeaker line for shorts.
• System power exceeds 400W – Check that
system power does not exceed 400W.
• Loudspeaker transformer saturation –
Check that proper loudspeaker EQ is being
used or use a high-pass filter for loudspeaker EQ.
• Line voltage too high (surge) – Check Error
Log for a rail voltage that exceeds 150V, in
70V mode, or 190V, in 100V mode.
• Line voltage too low (brownout) – Check
Error Log for a rail voltage which is lower
than normal by at least 20%.
• 70/100V mode switched with unit operating
– Check that output voltage and AC input
voltage selector are correct.
• Blown power supply fuse (as opposed to
AC line fuse) – Replace the fuse and perform the test procedures in this manual. If
the fuse blows again, replace the amplifier
module and retest.
AC Power Fault: Might be an AC line dropout
or severe brownout, or simply AC power
turned off without first placing the E4 Series
II in standby mode. You can check that the
power has been removed from the unit, or
that you experienced a power dropout.
Sleep Mode: The host microcontroller has
told the amplifier and power supply to turn
off. This only occurs in conjunction with
another alarm (usually AC power fault),
because it in itself is not an alarm condition.
When an AC power dropout occurs, the
amplifier immediately shuts the amplifier and
loudspeaker relay off, then the other processing is shut down. This all happens fast
enough to prevent data loss or corruption,
and to prevent loud pops in the loudspeakers. When this occurs you should check the
alarm history to determine what other faults
occurred at this time.
High-Frequency Sense Fault: This protection
mode is designed to prevent damage to the
amplifier or loudspeakers from excessive
high-frequency audio or ultrasonic energy.
The amplifier is not capable of sustained
operation at full power in the 10kHZ to
20kHz (+) range.
Generally, this fault results in a one-time 3second dropout. If, when the amplifier tries
to restart after 3 seconds, the excess HF is
still present, the amp (and loudspeaker
relay) will remain off for another 3 seconds
and the loop repeats. Six of these in a row
will cause the amp to shut down, and will
trigger a Retry Fault.
When this fault occurs you can check your
program material for excessive high-frequency content, or for a potential ground
loop which has created an oscillation internal
to the system. You can also reduce the
output gain for this amplifier zone in an
attempt to reduce the high-frequency energy
going to the amplifier.
86
TROUBLESHOOTING
Retry Fault: The amplifier has tried to start
up or recover from a fault condition at least
six times. When this occurs, you will need to
place the E4 Series II system in standby and
then press the STANDBY button again to
clear the fault, at which time the system will
again try to start up.
When this occurs you should check the
alarm history section of the Amplifier Alarm
to determine the exact fault type that triggered the Retry Fault.
Input and Output Alarm History: This part of
the Error Log displays the sequence of fault
conditions where “0” is the initial fault reported followed by “1-6”. These occur over a
very short period of time.
Solving faults reported in the Error Log
When errors are reported in the Error Log,
you can try to solve the problem by performing one of the following actions:
• On the unit’s rear panel, turn the POWER
switch to OFF. Wait a few seconds and turn
the POWER switch to ON. Then press
STANDBY on the front panel.
• On the rear panel, turn the POWER switch
to OFF. Disconnect all input/output signal
cables. Wait a few seconds and turn the
POWER switch to ON. Then press
STANDBY on the front panel. Reconnect
one cable at a time and check the Error Log.
This normally occurs due to one of three
reasons:
• The PC and unit under test are not connected via a “straight-wired” serial cable.
• Another software application has control of
the serial port. Applications such as the Palm
OS, or other audio applications control the
serial port while they are open. Close these
applications and click the TRY AGAIN
button.
• The unit is connected to another communications port. If this is the case you should
select the appropriate COM port and click
the TRY AGAIN button.
Note: Before dismissing the “Choose COM
port” dialog, select the COM 2 port and click
the TRY AGAIN button. Not doing this will
cause the COM 1 port to be locked. If the
port locks, you must restart your computer.

THEORY OF OPERATION
Power Supply / Amplifier PCB Overview
CAUTION: There are dangerous voltages present on most of the power supply and amplifier
circuitry. Under normal conditions, it can take 5 to 10 minutes after power is removed for these
voltages to discharge to a safe level. Please use extreme caution and resist the temptation to
probe during this period.

The FreeSpace
Class-D switching power amplifiers, four separate microcontrollers (uCs), and numerous DSP,
interfaces, memory, logic, analog and communication devices. The accompanying software
includes error flagging and logging features that will usually help you isolate the cause of any
failures.
Power Supply
The E-4 Series II power supply section consists of four sections. First is the main high-voltage
DC supply formed by the toroidal 50/60 Hz transformer, bridge rectifier (BR1) and filter capacitors (C1-C4). This is a conventional unregulated split supply (the only addition is SW1 to change
transformer secondary taps). The raw DC output is about
volt output, and
nal line voltage, these sag to about
thermal protection in the event of a catastrophic power amplifier failure.
E-4 Series II is a complex system that employs high-voltage direct-coupled
+ 130VDC when SW1 is set for 70
+ 170VDC when SW1 is set for 100 volt output. At full power output and nomi-
+ 110V and + 150V respectively. Fuses F1-F4 provide
The next power supply section, formed around TOPswitch
®
regulator U2 and transformer TR2,
is referred to as the “Standby Supply” because it is operational whenever power is applied to the
unit and the rear panel power switch is on. Its purpose is to supply approximately 9 volts (locally
regulated to 5 volts) to several microprocessors and other circuitry. These microprocessors
respond to turn-on stimuli, i.e. power-up via the E-4’s real-time clock, computer control or user
intervention via standby switch or wall plate.
The TOPswitch IC performs all the functions of a complete 130 kHz SMPS flyback-mode controller and switch, i.e. slow-start, current limit, overvoltage lockout, fswitch dither, low current
skip-cycle, etc.
The other, large TOPswitch section formed around U1 and TR1 response to “wakeup” commands from the E-4’s main host processor, which operates from the standby supply. It provides
+ 22 volts (locally regulated to + 15V) and +10 volts (locally regulated to + 5V and + 3.3V) which
powers multiple analog, DSP, communications and indicator sections throughout the E-4. The
forth output from U1 and TR1 (labeled -160) is more accurately described as “180 volts above
the minus rail”. This voltage is locally regulated to 12 volts, and provides the gate-drive current
for the main output FETs.
Also included on the power supply schematic sheet are two other ancillary circuits. U3A is a
resettable one-shot whose output is normally high with AC power applied. If there is an AC line
dropout exceeding approximately 2 cycles, a logic 0 from U3A is used to immediately shut down
the amplifiers and DSP in time to save all current configuration data and prevent any spurious
thumps etc. from appearing at the speaker outputs.
Q1 and Q2 form a simple buffer that switches the cooling fan from low to high speed if either of
the Fan-U or Fan-L signals are at logic 0. This occurs when the power amplifier thermal sensors
report a heatsink temperature of over 160
o
F.
90
THEORY OF OPERATION
Power Amplifier
Refer to the power amplifier channel block diagram below for the following information.
The E-4 Series II power amplifier section employs a number of protective devices and communication circuits to ensure continued reliable operation, and to enable reporting and logging of
any fault conditions. In addition, there are several measurement circuits, whose primary purpose
is to provide information to Bose
configuration of the E-4 Series II unit itself, and the speakers connected to it. The block diagram
provides a simplified view of one of the four channels, however many of the peripheral functions
are shared with one or more other channels. Refer to the schematics for more information on
exactly how the circuitry and functions throughout the units various PCB assemblies.
The power amplifier module itself consists of a single heatsink assembly with two circuit boards
mounted to it back-to-back. The upper PCB contains amplifier circuitry for output zones (channels) 1 and 2; the lower PCB contains amplifier circuitry for output zones 3 and 4, plus power
supply components shared by the entire unit. The power amplifier module receives analog
inputs and 2-way serial communications from the E-4 Series II DSP and host processor sections
via a 34-pin ribbon cable. Power is also supplied from the Amp/PS module to the rest of the unit
via this cable.
Component designators in the block diagram refer to channel 4, see the schematic diagram to
find appropriate designators for other channels. The core of the power amplifier section is a pair
of high voltage MOSFETs (Q10 and Q11). These are driven by a “Class T” hybrid control module from modulation pattern to drive Q10 and Q11’s gates. Contained in the hybrid module itself
are a proprietary analog/DSP IC operating from a single +5 volt supply, and a pair of high
voltage half-bridge gate drive chips including charge pumps for high-side drive. There are also
other discrete components to perform level translation, gain scaling, buffering, etc.

91
THEORY OF OPERATION
The Tripath’s modulation pattern has a no-signal center frequency of about 700 kHz. The
switching frequency varies downward as the signal level increases, reaching about 100 kHz just
before clipping. Near clipping, the switching pattern is further adjusted to provide soft clipping
behavior. This appears to be oscillation when viewed on a scope, but all of the artifacts are well
above the audio band, and the “fuzz” actually helps reduce the audibility of clipping. Choke L4
and capacitor C41 form a 2-pole low-pass filter at approximately 70 kHz to remove the switching
frequency from the audio output. C42, R84 and R85 are a Zobel network whose main function is
to damp the resonance of the L4/C41 filter with very high impedance or nonexistent speaker
loads. This network also does double duty: the voltage across R84 and R85 is rectified to
determine if the amplifier is being fed a signal with too much high frequency content. You’ll
notice that there is no analog feedback from the audio output. All of the feedback in the amplifier is derived by comparing the actual FET switching transitions with the predicted transitions,
thus avoiding the inherent delay of the output LC filter. “Servo Amp” A1 provides DC feedback to
insure that the entire amplifier’s output DC offset remains very low. This is especially important
in distributed sound applications, where the speakers are connected through matching transformers that have very low impedance at DC.
The voltages across R87 and R86 are sensed differentially and level-shifted within the Tripath
module (this is how excessive current i.e. a shorted load is determined). This over-current, or
main rail voltages that are too high or too low will cause the module to shut down very quickly
and output a logic 1 on the module’s “Fault” pin.
Protection
PIC microcontroller, U14, monitors amplifier functions including the Tripath’s “Fault” pin (and
numerous other inputs) and responds by turning the amplifier on and off by means of the
Tripath’s “Mute” pin. The speakers are also disconnected under U14s control via relay K1.
In order for the amplifier to become fully functional at start-up, the following conditions must be
true:
• The AC power must be OK.
• The heatsink temperature must be below 160
o
F.
• The “Wakeup” line from the host processor must be high.
• The “Amplifier Off” command (I
• The main rail voltages must be within prescribed limits (
2
C) from the host processor must be absent, i.e. set to “On”.
+100-190V).
• There must not be DC at the output (after a 1 second “servo setting time”).
• There must not be excessive high frequency content at the output.
In addition to this series of tests at start-up, the determination is made whether the unit is set for
70V or 100V output by measuring the + rail voltage <140V = 70V mode, >150V = 100V mode.
70V mode causes a 1 (+5V) output on U14s “Vshift” pin. This 1 causes a small amount of
current to be sourced/sunk into Tripath pins 37 and 38. These currents cause the Tripaths
internal Overvoltage/Undervoltage limits to shift downward corresponding to the
+ 130V rails vs.
+ 170V.
Once the amplifier is up and running, all of these parameters are monitored continuously, with a
o
few minor adaptations. If the heatsink temperature exceeds 160
F, the fan is switched from low
to high speed operation. If the power dissipation is still excessive, and the heatsink exceeds
o
210
F, the amplifier will be shut down until the temperature is under 160oF. Once the initial
voltage measurements are made, the Tripaths internal overvoltage/undervoltage sensing is
relied upon.
92
THEORY OF OPERATION
If anything other than a shutdown command causes the amplifier to go into protect mode (i.e.
AC dropout, overvoltage/undervoltage, short circuit, DC or high frequency), the speakers are
immediately disconnected, and the amplifier is shut down for approximately 3.5 seconds. It is
then restarted and checked again after a 1 second stabilization period. If everything is not OK, 6
more off-wait-stabilize-reset cycles are attempted, normal operation can resume after any of
these. If after 6 retries within 1 minute, everything is still not OK, the amplifier is returned to a
state that requires a “Standby-On” cycle, a “hard power down” or some other form of user
intervention to restart.
Measurement
Measurement of the rail voltages and numerous other parameters are accomplished via an
internal 10-bit A/D converter section in PIC uC U14. Most inputs to the A/D are multiplexed
(under the PIC’s control) via 8-channel analog switch U15. The A/D’s output is truncated to 8
bits and incorporated into the I
Heatsink temperature is monitored via U12, which provides a calibrated output of 10mV/
Several gain, precision rectifier, average circuits are provided to condition the following signals
for measurement via the MPX - A/D section (via voltage across R91):
• Amplifier input voltage
• Amplifier output voltage
• Amplifier output current
To provide repeatable, reliable measurements, the time constant of all these averages is
approximately 100 mSec.

FreeSpace® Installer™ software uses these measurements to calculate answers to
questions , such as; “Is the amplifier set up and running properly, and providing adequate output
voltage?” “Is the speaker line tapped for the proper output power on this Zone?”
Fault Logging
The amplifier PIC microprocessors are in continuous communication with the E-4 Series II host
processor via the I
2
C serial link. Pin 26 of the PIC micro is connected high or low on the two
amplifier PCBs so the host can distinguish between the upper or lower amplifier PCB. If any of
the events mentioned in the protection section cause the amplifier to shut down, an “Amplifier
Status Record”: plus a set of amplifier measurements (Vout, Iout, TEMP, Vrail, etc.) is saved into
flash memory. Some of the more common fault conditions can be identified by careful dissection
of these status records.
Amplifier Operating States
Pins 4, 5 and 6 on the PIC microprocessor programming headers (JP1 lower) or (JP2 upper)
provide a binary indication of which one of 6 states of operation the amplifier is in. If you monitor
these pins, you can observe the states being walked though, and determine where operation is
getting interrupted.
93
THEORY OF OPERATION
Amplifier Operating States (continued)
The order is pin 4 = MSB, pin 6 = LSB. For example, if pins 4, 5 and 6 measured high (+5V),
high (+5V), low (0V), you would be in state 6. Some of the states are transitioned through so
quickly that you would need a storage scope to verify operation in that state (ex.: state 4). Below
is a brief description of the states:
State 0 Amps and speaker relay OFF-waiting for Wakeup and/or Amp On command.
State 1 Delay- Wakeup received, wait 1 second for rail voltages to stabilize.
State 2 Test supply rails - return to state 0 if out of range. If OK, set to 70V or 100V mode
according to rail voltages.
State 3 Un-Mute (turn-on) amplifier (speakers off). Return to state 0 if Off command
received. Wait 1 second, but go to state 6 immediately if high frequency input
detected.
State 4 Test for power OK, DC, high frequency, overheat, etc. + Tripath faults. Go to state 5
if OK. State 6 if not OK.
State 5 Normal operation - Set speaker relay On (amp still running). Reset retry count to 0.
Watch continuously for Off commands or any faults.
State 6 Retry state. If retry count = 6, go to state 0. Mute amp, set relay Off. Add 1 to retry
count. Wait 2.5 seconds, then go to state 3.
E4 Series II DSP Theory of Operation
1. Overview
The E-4 Series II DSP section consists of five boards manufactured as a single panel. Unregulated power is distributed to the boards and each, except the flash card, contains its own regulators. The DSP board contains the 56K DSP and the 80C251 host processor along with its
subordinate PIC processor for peripheral control. This board also carries the audio codecs and
their associated analog circuitry. Two audio inputs are line level and two may be configured for 0
to 60 dB of gain. The direct input bypasses the DSP and codecs and allows a signal to directly
drive the amplifier system. A ribbon cable transports the audio output signals, various control
and monitoring signals, and raw power between the amplifiers/power supply and the DSP
system.
A flash memory chip that holds the host operating program and system configuration information is mounted on a small card that plugs into the processor board. The LED board holds the
front panel indicator LEDs, standby button, and the USB interface connector. The wall plate
connectors, contact closure input, direct audio output, and music on hold output are on the Wall
Plate Sense board at the back of the unit. The Auto-Volume Mic Sense board is mounted above
the Wall Plate Sense board and also contains the RS-232 connector.
When the system is on, it can be in one of two states: standby or operating. When the system is
in standby, the host and peripheral processors are powered up and functioning as are the LED
and Wall Plate Sense boards. The power to the amplifiers, the Auto-Volume Mic Sense board,
the DSP section and the analog I/O circuitry and codecs is shut down. When you bring the unit
out of standby all sub-systems are powered.
94
THEORY OF OPERATION
2. DSP Board
Digital power on the DSP board is regulated by a 5 volt (U547) and a 3.3 volt (U550) voltage
regulator. The analog section of the board, running from plus and minus 15 volts (U548) (U549),
and 5 volts (U551), is powered only when the system is not in standby. Power on system reset
is managed by (U552).
The DSP is a Motorola 56362 (U517) running at 112.896 MHz. An internal PLL multiplies the
22.579 MHz crystal oscillator (U527) frequency by five. The oscillator runs from the 3.3V supply
and also drives a D flip-flop divide by 2 and level shifter that is made from ½ of (U525). The
112.896 output drives the MCLK inputs of the audio codecs and (U526) synchronous counter
that serves as the clock divider chain to provide the 2.822 MHz SCLK and the 44.1 kHz LRCK.
The DSP sub-system also has flash memory (U516) and three 128K by 8 static RAMs (U513,
U514, U515) running from the 3.3 volt power supply. The host processor holds the DSP subsystem in reset with power off when the E-4 Series II is in standby.
The host processor sub-system is always running when the E-4 Series II is powered up. The
host processor sub-system consists of (U520), an octal D flip-flop (U519) to latch the low order
address lines, (U521) used as a memory block decoder, (U518) a 32K by 8 static RAM and
(U701) the flash memory on the daughter card. It communicates with the outside world through
its RS-232 port buffered by a MAX202E (U524) or through the USB interface on the front panel
board.
The microprocessor (U544) serves as a peripheral controller to extend the I/O capacity of the
(U520). The host communicates with it over the I
and the USB bus interface (U106) that is mounted on the front panel board.
Pressing the standby button on the front panel sends a signal to the PIC that is relayed to the
host over the I2C interface. The host then sends a wakeup signal to the power supply by lowering a port line that is buffered by one section of (U522) that in turn drives PNP inverting transistor Q501.
Strobe signals from the PIC drive three gates on (U522) to gate serial clock signals from the
host that drive the three audio attenuators (U531, U203, U211) in the system, one on the DSP
board and two on the mic sense board. These gated clocks along with the serial data line and
the I/O clock for the wall plate board then are buffered through (U553) so that drive is disabled
when the unit is in standby and power is removed from the DSP analog section and the two rear
auxiliary boards.
Two serial in, parallel out shift registers (U545, U546) are driven by the PIC to provide control
bits to the gain controls on the two mic inputs. The final output bit from the second shift register,
controls NPN transistor Q503 to output a control signal.
The PIC also contains an eight input 10 bit A/D converter. The four sense lines from the auto
volume mic sense circuits drive the first four inputs and the four sense lines for the amplifier
sense circuits drive the second four inputs. Each input has a .01 uF capacitor to minimize high
frequency noise and a dual protection diode connected to ground and the 5V power rail. Header
JP501 is present to allow the PIC to be programmed on the circuit board.

THEORY OF OPERATION
The analog section of the DSP board contains the two stereo codecs (U503, U507) and their
associated analog input and output circuitry. Line 1 and 2 each have two inputs that are resistively mixed and buffered through difference amplifiers (U529, U532). Each of the difference
amplifiers feed a channel of the volume control (U531) that in turn drives the two dual op-amps
(U501, U504) that convert the single ended signals to differential drive for the codec.
Mic in and Page in are balanced inputs, each driving an instrumentation amplifier (U537, U540).
These two channels each have a voltage regulator (U536, U539) that can be enabled by the
host to provide phantom power to external mics. The gain of the voltage regulator is controlled
by the host switching on analog switch sections (U541, U542, U543) that connect gain control
resistors. The range of gain is 0 to 60 dB in 10 dB increments.
The outputs of the instrumentation amplifiers are each served by ½ of an op amp (U538) to a
fixed DC offset of 2.5V to provide one half of the differential drive to the second codec. Each
channel is inverted by half of a dual op-amp (U505) to provide the second phase of differential
drive to the codec. Each of the four input channels is fed to a multiplexer (U535) that selects
one channel under host control for output as music on hold.
The four differential outputs of the codecs drive four identical circuits built around switchable
amplifiers (U509, U510, U511, U512). One differential input of each is configured as a low-pass
filter and differential to single ended converter and is fed from a codec output. The second input
is connected to a common input signal, the direct input. A PNP transistor circuit (Q502) detects
ground on the PTT input and switches the switchable amplifiers to the direct input while also
signaling the PIC to inform the host that an override is occurring. The four switchable amplifiers
drive the power amplifier inputs from the selected input signal path.
The outputs from the switchable amplifiers also drive four channels of amplitude sense circuitry.
Each sense path consists of an op-amp gain stage followed by a low pass filter, a high pass
filter and a precision rectifier/average circuit. The op-amps are contained in dual op amps
(U700, U706) and quad op-amps(U702, U703, U704, U705).
3. LED Board
The LED board contains the front panel indicator LEDs, the standby switch and the USB connector and interface circuitry. Power is applied to this board even when the E-4 Series II is in
standby and is regulated to 5V by U105 voltage regulator and to 3.3V by U107 voltage regulator. Serial input from the host on the DSP board drives a sequence of three serial in, parallel out
shift registers (U102, U103, U104) to drive the LEDs. To reduce power consumption three
inverters from U101 are configured as an oscillator to multiplex the LED drive. Two more of the
inverters are used to buffer and debounce the standby switch. When the standby button is
pushed the signal is detected by the PIC processor on the DSP board, which then communicates over the I
board to allow the host processor to communicate with an external PC through the USB interface IC (U106).
4. Auto-volume Microphone Sense Board
The auto-volume microphone sense board contains the input and level control circuitry for four
sense mics and an RS-232 connector to allow the E-4 system to communicate with an external
PC. Power is not applied to this board when the E-4 is in standby. The board regulates analog
power supply voltages with a positive 15V regulator (U216) and a negative 15V regulator
(U215). There is also a positive 8V regulator (U204) to provide power to the external sense
mics.

THEORY OF OPERATION
Each mic sense path consists of input protection circuitry and a resistor to the 8V supply followed by a 330uF DC blocking capacitor, input protection diodes to the plus and minus 15V rails
and an op-amp serving as an input gain stage of 37dB. The output of the op-amp passes
through another DC blocking cap to ½ of a volume control IC. This output passes through
another capacitor into an op-amp gain stage followed by a low-pass filter, a high pass filter and
finally a precision rectifier/average circuit and off the board to one of the PIC A/D inputs. There
are two attenuators (U203, U211), two dual op amps (U206, U213) and four quad op amps
(U207, U208, U214, U215) on the board.
5. Wall Plate Sense Board
The wall plate sense board contains the circuitry to scan up to four wall plates that are connected through four RJ-45 jacks and to drive the LEDs on the wall plates. In addition there are
connectors and passive protection components for the music on hold output, the line 4 expansion output and its associated control line, and the control input to allow an external device to
wake up the system.
Power is applied to the board even when the E-4 Series II is in standby and is regulated for the
board and the external wall plates by a voltage regulator (U401). The wall plate input lines are
scanned by three parallel in, serial out shift registers (U404, U405, U406) Resistors on the wall
plate sense board pull the input lines up, switch closures on the wall plates pull the inputs down.
Two serial in, parallel out shift registers (U402, U403) apply multiplexed drive to the LEDs on the
wall plates in the interim when the switches are not being scanned.
6. Flash Memory Board
The flash memory card is powered from the main DSP board. The board contains a 2 Mb, 5V
flash ROM (U701) and power supply bypass capacitor. This memory stores the system configuration data as well as the host microprocessor operating program.
