- The * sign next to a control signal name indicates that this control is active low
The Vetta Combo electronic circuitry is distributed across 8 PCBs:
- Vetta Power supply PCB
- Vetta Main PCB
- Vetta Power amplifier PCB
- Vetta U.I. (User Interface) Left PCB
- Vetta U.I. Right PCB
- Vetta Guitar Input PCB
- Vetta Headphone Output PCB
- Vetta Speaker Output PCB
Power supply system:
On the Power Supply PCB:
The main components of the power supply system are located on the power supply PCB. This
is a switch mode power supply. Directly connected to the AC input is the line filter. The line
filter limits the noise that the power supply injects into the AC line. L1 and L2 are common
mode inductors, which work with “Y-caps” C6, 7, 43, 44, 45 to filter common mode noise.
Common mode noise is on both the line and neutral. A Y-cap is connected from line or neutral
to the chassis. The chassis should be connected to earth ground. There are two X-caps - C3, 43
which are connected from line to neutral and they filter differential noise. Service note: Both
X and Y caps go through special testing from the safety agencies and should only be replaced
with approved parts.
The fuse F1 provides protection in case of a failure in the primary circuit. Service note: It is
very unlikely that this fuse will blow without a catastrophic failure. Never replace the fuse and
apply power before repairing any failed components.
The negative temperature coefficient (NTC) thermistor RT1 limits inrush current when the unit
is cold.
D1, C1, and C2 comprise a full-wave, or voltage doubler rectifier circuit. If a jumper is
installed across J5, the unit is in voltage doubler mode and the nominal AC input range will be
100 to 120VAC. If no jumper is present the range is 200 to 240VAC. When the jumper is set
properly for the available AC, the DC voltage across C1, C2 is a roughly constant 350VDC.
Service note: If no jumper is installed (240VAC mode), and the unit is operated at 120VAC, it
will function but it will not be able to output full power. If the opposite condition is present
(jumper in 240VAC) the unit will get damaged (350V across 200V caps). Obviously, great
care should be taken to avoid this condition.
The power converter is a flyback topology (The correct term for the magnetic element in a
flyback converter is a coupled inductor but it is commonly referred to as a flyback transformer.
VETTA Theory of Operation………………Line 6 confidential ……………………………. Page 1 of 18
An inductor can store energy while an ideal transformer transfers energy but does not store it.
We won’t buck tradition so we’ll call it a flyback transformer).
The basic operation is to apply the input voltage across T2-A by turning on Q3, 15. Energy is
stored in T2 and all of the secondary diodes are reverse biased. When Q3, 15 turn off, the
stored energy is transferred to the outputs. As the voltage fly’s back, the secondary diodes are
forward biased. Voltage clamp D17, C22, R17, 18, 20 limits the voltage across Q3, 15 by
providing a path for primary current flow while the energy is being transferred from primary to
secondary. The secondary voltages will track each other quite well as long as a nominal load is
applied: Service note: This supply is not designed to be operated with no load, and this
condition may over stressed the output caps. Constructing a test fixture with the following
resistors will allow test bench operation: 390Ω 10W from J6.2 – J6.3; 390Ω 10W from J6.4 –
J6.5; 10Ω 2W from J6.5 – J6.6; 330Ω 2W from J2.1 – J2.2; 330Ω 2W from J2.3 – J2.2; 10Ω
10W from J2.4 – J2.5
A buck regulator consisting of IC U3 Inductor L6 and Capacitor C59 regulates the voltage
generated by winding T2_B. This generates an 8V regulated output. Also, the voltages
generated by the T2_D winding are stepped down to ±18 V by the linear regulators U8 and U9.
The Voltage Feedback circuit monitors secondary voltages (+8Pre, +45Pre, -45Pre and
PS_Valid). The PS_VALID signal is AC coupled into the feedback and does not play a part in
determining the DC output voltages. Transistors Q1, 4, 5, 8, 9, 10, 12 comprise a circuit that
does level shifting, voting and output voltage switching. The regulation scheme looks at +8Pre,
+45Pre, and -45Pre and decides which is at, or below, their nominal regulation point and
regulates this output. The other outputs are ignored and allowed to exceed their regulation
points.
This circuit controls the duty cycle of the primary switching through the opto-isolator U1 and
shunt regulator U4 on the secondary side. On the primary side, controller IC U2 (U2 is itself
supplied by the T2_E secondary winding) drives the gates of the main MOSFETs through
buffer transistors Q2, 11. This provides the voltage regulation feed back loop. A thermal
protection circuits monitors the temperature of the primary components through the thermistor
NTC2, and shut down the controller IC U2 if necessary.
The sequence of events at application of power is as follows: C1, 2 are charged and current
flows through R1, 2. The PWM chip U2 is in a low power mode and the main MOSFETs are
not being switched. When the voltage at +HK (house keeping) reaches about 17V, the PWM
chip starts running and the main MOSFETs start switching. The current supplied by R, 1 is not
sufficient to allow continued operation so the voltage at +HK drops. If the secondary voltages
ramp up properly, then winding T2-E will power +HK before it drops to the lower cut off point
of about 10V. If there is a short on the output or one of several other failures, the PWM will
shutoff at +HK=10V and +HK will start to charge again. This charge and discharge cycle will
continue at a rate of several Hz. Service note: Do not attempt to monitor primary voltages
with an oscilloscope. The safest method is to use an isolation transformer. Removing the
‘scope ground connection or “floating” the scope is potentially lethal for the technician or
others that may come in contact with the ‘scope.
VETTA Theory of Operation………………Line 6 confidential ……………………………. Page 2 of 18
In addition the Z_SELECT signal controls the voltage feedback circuit and allows to select
one of two sets for DC output values:
On connector J6 to
On connector J2 to
the Power Amp
the Main PCB
+ LO - LO –HI +20V -20V PS_Valid +8V
If Z_SELECT is set at +15V
+32 -32 -36 +18 -18
+20
+8
If Z_SELECT is set at 0V (or floating) +45 -45 -50 +18 -18
+30
+8
This feature is used to adjust the voltage rail of the power amps (+LO and – LO) in function of
the speaker impedance that they currently drive. For 8 Ohm load the Z-select line will be left
floating and the supply will provide ±45 Volts. For 4 Ohm load the Z-select line will be pulled
to 15V and the supply will provide only ±32 Volts. This will result in the same maximum
audio power on each load setup.
The PS_VALID validate the other supplies. A high level indicates that all the supplies are
within a valid range. This line will also go low before any of the supply start to drop
significantly.
Note that the ground references for the voltages on J6 (to power amp) and J2 (to main PCB)
are not connected together on the supply. The same is true of the AGND and DGND signal on
J2. They will be connector together only through the Main PCB and Power Amp PCB.
On the Main PCB:
The ±18V (labeled ±20V on the connector J49) are further stepped down and regulated ±15V
by the linear regulators U7 and U8. These ±15V supplies directly drive a number of Op amps
on the main board and on the power amp PCB. The ±15V are both further filtered by an RC
network (R165 and R166) to create the ±15V_IN supplies, which are used by the op amps of
the guitar input circuitry. This extra filtering removed any possibility of supply induced audio
feedback between the audio output and input stages. Finally, the ±15V are also delayed and
slowly ramped up over a two seconds period after the main power is turned on (detected by the
state of PS_VALID) by the circuitry around Q2 and Q1. The resulting ±15VDEL supplies are
used by the op amp U14 which drives the Direct output connectors. This setup limits the audio
thump, which would otherwise appear on the direct outputs when the main power is turned ON
or OFF.
The +8V is stepped down and regulated to +5VA (A= Analog) by U25, +5V by U6 and +3.3V
by U8.
The +5VA is used only for the Audio converters U19, U20, U18, and U16.
The +5V supplies the logic on the Main PCB and the U.I. PCBs.
The 3.3V supplies the logic on the main PCB including the microprocessor (Coldfire) U27 and
the two Sharc DSPs U35 and U36.
The +8V also directly supplies the FBX (Foot Controller Option) where it will be regulated
down to 5V.
VETTA Theory of Operation………………Line 6 confidential ……………………………. Page 3 of 18
While the main power is turned ON, the 3.3V supply the SRAM U29. When the main power is
OFF the SRAM supply is maintained (to avoid memory lost) by the battery BAT2 voltage. The
battery voltage should be above 2.7V. If it drops below the battery should be replaced. The
current draw on the battery, while the main power is OFF, should be less than 3.7 micro amps.
This will correspond to a maximum voltage of 100mV across R185. With this maximum
current, and a fresh battery, the battery life should be a minimum of six years.
On the U.I. PCBs:
After arriving on the U.I. Left PCB, the +5V and its ground (GND) are separated into two local
signal pairs +5V/ GND and +5VA/AGND. The separation between these pairs is only achieved
through the U.I. PCB layout. The +5VA/AGND drives the 10 potentiometers and the front
panel ADC U10. The +5V/ GND drives all other circuits on the front panel PCBs. This setup
improves the potentiometer jitters immunity.
VETTA Theory of Operation………………Line 6 confidential ……………………………. Page 4 of 18

Audio system:
On the Main PCB:
There are four independent audio circuits on the main PCB. The only audio connection
between them is through the DSP signal path.
Guitar input (Page 7 of 8 of Main PCB schematics):
The guitar input is first buffered and amplified on the Guitar Input PCB before it reaches the
Main PCB at connector J26 (15Vpp @ 5Vpp at the guitar jack). An analog switch made of U15
and U22 allows for selecting the input signal either from J26, or from an optional I/O PCB
connected to the main PCB at connector H2. This option board is currently not available, and
until then this switch will not be used and is permanently switched to the J26 input (= The
Guitar/Line_Select control signal should be at 3.3V). After the switch, the signal is spliced into
two branches. R96 and R23 divide by 3 the upper branch to +/-2.5 VPP (@ 5Vpp at guitar
input). C40 allows this signal to be DC biased at +2.5V by the ADC input. Q7 and Q8 clip the
signal to a maximum range of 0/5V. The signal then enters the right channel of the ADC U19.
In the lower branch, U22-B adds a gain of 5.3 to the signal. C39 allows this signal to be DC
biased at +2.5V by the ADC input. D14 and D15 limit the maximum signal swing to a -0.6V
/+5.6V range before entering the left channel of ADC U19. The net result is that the ADC left
channel is feed by a signal 16 times larger than the one on the right channel. Once these signals
are converted and moved into the DSP#1, the DSP code will monitor the amplitude of the
signals and use the one of the two versions most appropriate for the current input level. This
scheme allows for significantly improving the signal noise and low-level distortion
performance of the ADC.
Direct output (Page 5 of 8 of Main PCB schematics):
The direct output audio circuit supplies the audio signals to the Direct ¼”jacks and XLR
Outputs. The digital signal from DSP#2 feeds DAC U21. The left and right differential outputs
of the DAC are amplified and Low Pass filtered (FC = 31KHz) by U18_A and B. U18 outputs
directly feed the headphone amplifier made of U24 and U23. They also feed a differential
buffer made of U14 which drives the XLR balanced outputs, and, through a divider made of
R12/R6 R13/R7, the ¼” unbalanced outputs. Notice that U14 is supplied by ±15VDEL
supplies (see Main PCB power supply operation for the justification).
Power Amp output (Page 6 of 8 of Main PCB schematics):
The power amp output audio circuit supplies the audio signals to the power amp differential
inputs. The digital signal from DSP#2 feeds DAC U20. The left and right differential outputs
of the DAC are amplified and Low Pass filtered (FC = 31KHz) by U13_A and U4_A. Their
outputs directly feed the left and right positive inputs of the power amp through connector
H12. (U39 shown on schematic version C was removed and bypassed by an ECO prior to
FCS). U13_B and U4_B invert the signal and feed the left and right negative inputs of the
power amp.
Effect loop (Page 6 of 8 of Main PCB schematics):
The effect loop audio circuit provides a path to bring the analog FX Return signals into the
DSP#2 and to bring DSP#2 digital audio output to the analog FX Send.
FX Return:
VETTA Theory of Operation………………Line 6 confidential ……………………………. Page 6 of 18
Diodes D3/D4 and D5/D11 protect the op amp U10 from overdriving and electrostatic
discharges. R44/R170 and R43/R169 attenuate the FX Return signal from the maximum
specified 20Vpp to 5Vpp. R44 and R43 also protect the input of the CODEC ADC in case the
voltage would exceed +/-2.5V. C14 and C15 allow the signal to be DC biased at +2.5V by the
ADC input. D8/D7 and D10/D9 are not installed on the PCB. The ADC output of CODEC U16
feed DSP#2.
FX Send:
The differential outputs of CODEC U16 DAC are amplified and low pass filtered (31KHz) by
U11_A and B. U11 outputs feed the FX Loop ¼” jack (20Vpp max)
On the Power Amp PCB:
The differential inputs at connector P1 feeds the two power amps. Notice that the gain of the
power amp is conditioned by the status of the Z-Select line. This allows for setting the
maximum power amp output swing, and power, in function of the current load impedance (4 or
8 Ohm). Notice also that the power amp can be muted by the POWERAMP_MUTE* signal
(0V = muted, above 3V = un-muted)
On the Speaker Output PCB:
The function of SPLIT switch on the Speaker Output PCB is described in the VETTA User
Manual. The wiring of the ¼” jack J9 is such that if no jack is plugged into it, the split switch
SW2 default to the Split OFF position. This was designed so that if no external speaker is
plugged in the LEFT speaker output jack the split switch will have no effect on the speaker
signals routing.

Clock system:
Except when the digital I/O option board is used (currently not available), all the clocks are
contained within the Main PCB.
There are two master clocks: CLK_30 (30MHz) and CLK_40 (40MHz).
The crystal oscillator Y3 generates the CLK_30 clock. Its only purpose is to set the execution
speed of the two Sharc DSP U35 and U36.
The crystal oscillator Y1 generates the CLK_40 clock. It has a number of distinct functions:
1). It sets the execution speed of the microprocessor U27 and drives all its peripheral access
timing through the PLD U28.
2) It provides the run rate for the MIDI and FBX interface (internally generated in U27).
3) After being divider by four by the flip-flop U32 it becomes the 256FS_CLK (10MHz) which
is the master clock for the audio sample rate. U17 implements a two-way switch, which allows
for using an alternate clock generated on a future digital I/O option card. This card is not
currently available and the switch should always be set to the U32 divider branch (= the
SEL_LOCAL/OPTION* control signal should remain high). The 256FS_CLK drives the
CODEC U16, which generates the FS-CLK (256FS_CLK/256= 39.0625KHz) and the
64FS_CLK (FS_CLK * 64 = 2.5MHz) signals. After buffering by U34 the 256FS_CLKB,
64FS_CLKB1, and FS_CLKB1 clocks drive the guitar input ADC U19 and the direct and
power amp output ADC U21 and U20. Also, after buffering by U3, the 64FS_CLKB2, and
FS_CLKB2 drive the DSP #1 and #2 to synchronize the DSP processing with the converters
sample rate.

Bus system:
DSP #1 U35 and #2 U36 share a common 32 bit wide data bus named DSP_DATA[00:31] and
a 24 bit wide address bus named DSP_ADDR[00:23]. These buses allow for communication
between the DSPs and with the SDRAM. The SDRAM can be configured either with two
1Meg. by 16 ICs (U37 and U38) or two 4 Meg. by 16 ICs (U39 and U40). The current Main
board is stuffed with U37 and U38 (1Meg.) (U39 and U40 are not installed on the PCB). Since
each SDRAM IC is only 16 bit data wide they each carry only half of the DSP data bus. U37
and U38 are accessed together as a single 1 Meg by 32 bit wide SDRAM with U37 carrying
the 16 less significant bits and U38 carrying the 16 most significant bits. These two busses also
permit communication between the DSPs and the microprocessor U27. The address bus lower
10 bits [00:09] can be driven by the microprocessor through the tri-state gate U41. The lower
16 bit of the data bus [00:15] can be bidirectionaly connected to the microprocessor address
bus through the bidirectional buffer U42. This interface permits to move the DSP code from
the microprocessor flash memory U26 into the DSP memory upon power on initialization. It
also permits to send new parameters to the DSP when a new patch is recalled or a U.I. control
is changed. This interface must be working for the DSP to run valid code after power on.
On the microprocessor side, the 32-bit data bus is called HOST_D[00:31], and the 24-bit
address bus is HOST_A[00:21] (bit 22 and 23 are not used). Through these buses the
microprocessor can access the FLASH memory U26 that holds the microprocessor and DSP
code. The data to the FLASH is bidirectional allowing the microprocessor to transfer new code
from MIDI to the FLASH thus allowing reprogramming the VETTA software operations from
the outside. These buses also connect to the SRAM U29, which is permanently supplied by a
battery, and hold the user defined data setups.
Finally, to allow bidirectional communication with the U.I. PCB, bit 24 to 32 of the data bus
are bidirectionaly buffered by U30 to the U.I. bus FB_D[00:07]. U31 buffers the 3 less
significant bits of the address bus.

I/O system:
The following Input and Output (I/O) signals control the VETTA operations
GUITAR_IN_SENSE
This input signal is generated on the Guitar Input PCB and read on the Main PCB by an I/O pin
of DSP #1. It is high when a jack is plugged in the guitar input and low otherwise.
When this signal is read low (= no jack plugged in), the DSP mutes the audio signal path in
order to keep the noise on the audio outputs at a minimum
On the Option Board (not available yet):
LINE_IN_SENSE (USED ONLY WITH OPTION BOARD PRESENT)
This input signal is generated on the option board (when present) and read on the Main PCB by
an I/O pin It is high when a jack is plugged in the Line input of the option board and low
otherwise. As with the GUITAR INPUT, muting is applied to the DSP if the LINE input is
selected and no jack is present (=Low).
Option card ID reading (USED ONLY WITH OPTION BOARD PRESENT)
If an option card is installed, the firmware can read from it an eight-bit serial ID code unique to
that type of card. If no card is installed the ID read will be 0FFh
The IDs currently assigned are:
000h =
Digital OUT only card
001h =
Digital IN and OUT card
…
Unused
0FFh =
No card
Hardware version reading
The three lines BDM_DDATA0 = bit 0, BDM_DDATA1 = bit 1, and BDM_DDATA2 = bit 2
can be read at anytime by the microprocessor U27 to determine what hardware revision of the
Main PCB hardware is being used. The code read is determined by the set up of the three
resistors R125, R130, and R131 that can be installed to be either pull down or pull up.
This allows for future version of the firmware to automatically adapt to older Main PCB
hardware version. The first board version released in the market had code 0 (= all three
resistors are wired to be pull down). If necessary, following version code will increment by 1.
Seven hardware IDs from 0 to 06h are allowed. The hardware differences of relevance to the
firmware between the Main PCB versions will be documented in ECOs. Code 07h is reserved
for test mode.
Test mode reading
When, while during the firmware initialization, the three lines BDM_DDATA0 = bit 0,
BDM_DDATA1 = bit 1, and BDM_DDATA2 = bit 2 are read all high (07h) by the
microprocessor U27, it signals that the MAIN BOARD is being tested (likely on a bed of nail
fixture), and that the test firmware should be executed instead of the regular firmware. Those
three lines can be forced high by the tester’s bed of nail by forcing the right side of R125,
R130, and R131 to 5 volts.
VETTA Theory of Operation………………Line 6 confidential ……………………………. Page 13 of 18
Z-SELECT status reading (CURRENTLY UNUSED)
The status of the Z_SELECT signal can be read by the microprocessor U27 through the circuit
made of Q6 and Q9 (page 8 of 8 of the Main PCB). The reading is done in two paths.
- First the BDN-DDATA3 line is read while the Option_Sel_3* line is held low. This first
reading brings bit 0 of the Z_Select status.
- The BDN-DDATA3 line is read again while the Option_Sel_3* line is held high. This
second reading brings bit 1 of the Z_Select status.
- The status of the Z_Select is then determined as follows
4 Ohm (+15V) 0
8 Ohm (open)
16 Ohm (-15V)
Bit 0
1

GUITAR/LINE*_SELECT (USED ONLY WITH OPTION BOARD PRESENT)
This output control line, generated by an I/O pin of DSP #1, controls the analog switch made of
U15 and U22 (page 7 of 8 in Main PCB) and selects which one of the GUITAR or LINE jack
(on the option board) is active. A high level (3.3V) selects the GUITAR jack and a low level
selects the LINE jack. Due to the possible presence of different DC offset level on each input
an audio click could appears on the output when this signal is switched. To avoid this the
following switching sequence is used:
1) Ramp the amplitude of the DSP audio path to 0 over approximately 20ms second
2) Switch the GUITAR/LINE_SELECT Line.
3) Ramp the amplitude of the DSP audio path back to its original level over approximately
20ms second
NOTES:
- On all three VETTA versions the LINE INPUT is available only if a DIG I/O card is installed. Therefore if a
DIG I/O card is not installed the GUITAR / LINE selection page is not available on the menu.
RESET-IO*
This output line, generated by an I/O pin of DSP #1, resets the main ADC, both DACs, the
effect loop CODEC, and the option card (when present). It is pulsed low for a few
microseconds as soon as the firmware starts to run.
FX_RET_SENSE
This input signal, generated by effect return ¼” jack J10 (page 6 of 8 of the Main PCB), is read
by an I/O pin of the DSP #1. It is high when a jack is plugged in the FX LOOP RETURN jack
and low otherwise. When no jack is sensed on this input (= low), the DSP Direct Level on the
diagram below is set a 1 and the Effect Level at zero.
Direct level
FX LOOP SEND
FX LOOP RETURN
Effect level

POWERAMP_MUTE *
This output signal is generated by an I/O pin of DSP #1. When low it mutes the power amps. It
is kept low from the start up of the firmware until all DSP code is downloaded and running, all
memory is cleared, and the +/- 15DEL (delayed +/- 15 V supplies) are up. This last item takes
about 2 seconds from the time the AC power is turned ON. The POWERAMP_MUTE* signal
is combined with the PS_VALID signal (see power supply PCB) by D16, R175 and R174
(page 6 of 8 of the Main PCB). This arrangement helps muting the power amp as soon as the
power supply starts to fall, and therefore limits the amount of audio thump when the power is
turned OFF.
MONO/STEREO*
This input signal is generated on the Speaker Output PCB, and is read by an I/O pin of DSP #1.
Since the VETTA Combo always runs in stereo, it is grounded and will always read low. This
signal will be used in the VETTA Head.
When the unit is running in VETTA COMBO mode (as determined by a flag stored in the flash
memory) the MONO/STEREO* input is ignored and the unit defaults to stereo.
Z_SELECT
The Z_Select line is an analog signal generated on the Speaker Output PCB. Its level indicates
the current setting of the Power Amp output impedance. Its analog voltage level versus
speaker’s impedance setting is a as follows:
4 Ohm
= +15V
8 Ohm
= 0V (or open)
16 Ohm
= -15V (Used only on VETTA Head)
The status of the Z_SELECT line affects two parameters in the VETTA
1) It changes the gain of the power amp (see Audio System)
2) It changes the rail voltages of the power amp (see Power Supply System)
HEADPHONE_SENSE
This input signal is generated on the Headphone Output PCB, and is read by an I/O pin of DSP
#1. It is high when a jack is connected to the headphone output jack and low otherwise. When
a jack is connected into the Headphone Output (presumably a headphone), the DSP signal
going to the power amp DAC (U20) is muted.
When the unit is running in VETTA HEAD mode (as determined by a flag stored in the flash
memory) the status of this line is ignored and the mode default to “no headphone plugged in”
(= do not turn off the power amp).
LCD Temperature compensation:
Because a fair amount of heat is generated in the Vetta chassis, and because the contrast of the
U.I. LCDs is significantly affected by this heat, the VETTA implement a compensation scheme
to automatically adjust the LCD contrast setting in function of the chassis internal temperature.
To this effect, the temperature under the large graphic LCD is sensed on the U.I. Left PCB by
U11 (page 1 of 3 of U.I. left half). This IC generates a DC voltage proportional to the sensed
VETTA Theory of Operation………………Line 6 confidential ……………………………. Page 15 of 18
temperature (GRAPHICLCD_TEMP line). This voltage is digitized by the U.I. ADC U10
(page 2 of 3) and read by the main PCB microprocessor. The microprocessor code uses this
temperature reading, plus two other parameters, to determine the required LCD contrast
through the following process:
1) According to the VETTA version an initial value is selected which optimize the viewing
angle as follows:
- Bottom for VETTA Combo
- Front for VETTA Rack (not available)
- Top for VETTA Head
2) The front panel temperature reading is scaled by a function and added to this initial value.
This automatically corrects for the LCD contrast change with temperature.
3) The U.I. user adjustable LCD contrast setting is scaled by a function and added
The scaling functions, initial values and contrast values are different for the graphic and
alphanumeric LCD, but the temperature reading is common to both.
The following diagram represents the firmware flowchart for one of the LCD

LCD CONTRAST Pulse With Modulator
LCD Bias Voltage
The result of this computation is used to control the duty cycle of two100Hz pulse generators
implemented by the main PCB microprocessor U27 and the two U.I. PCB flip-flops U1-4 and
U1-B. Each of these flip-flops output is then rectified by Q18, R4 and C24 for the graphic LCD
and R1, R3 and C23 for the character LCD. This produces two negative voltages proportional
to the generator’s duty cycle. These voltages are then sent to the LCDs contrast adjustment pin.
While the Vetta is in test mode (power the unit with the REVERB switch depressed), the
software does not perform the temperature compensation algorithm. For this reason, when the
Vetta is running in test mode, and the unit had had a chance to significantly warm up, the
contrast of the LCD will be significantly off.
U.I. potentiometers:
The 10 U.I. potentiometers (6 on the left side, and 4 on the right side) provide a voltage from 0
to 5V. These voltages are digitized by the U.I. ADC U10. The resulting serial stream is read by
the Main PCB microprocessor U27.
VETTA Theory of Operation………………Line 6 confidential ……………………………. Page 16 of 18
U.I. LEDs:
All of the U.I. LEDs (except the LCD’s backlight LEDs) are multiplexed in a 15 row by 5column matrix. The rows of the matrix are driven by U4, U3 and the associated 16 buffer
transistors. The columns of the matrix are directly driven by U9. The multiplexing cycle is
about 10ms long. The matrix driver circuit resides on the Left U.I. PCB (page 3 of 3 of left U.I.
PCB).
U.I. Switches and encoders:
All of the U.I. switches are read in a 5 by 7 matrix. One side of the matrix is driven by U5, and
the other by U7 (page 2 of 3 of left U.I. PCB). The encoders, except E8 (program select), are
read in a 12 by 2 matrix driven by U6 and U4. E8 is read directly by U6. Notice that the
encoders are 24 positions except for E9 (amp select) and E14 (Page).
U.I. LCDs:
Both LCD modules are written to and read from through the U.I. PCB parallel bus FP_D[0:7].
Their electronic is supplied with the +5V. Their backlight LED are also supplied from the 5V
through current limiting resitors, R46 for the graphic LCD and R12 for the Character LCD.

Page 19 of 51
Vetta Head Assembly Instructions Rev D1
d) Attach Foam Block to the chassis and the Main Board PCB
Cut foam block (#30-75-0010) into 1/3 of length. Attach the block to the indicated position
adjacent to the RJ45 jack opening (just below the expansion slot cover).
Position so foam block
lies about 1/16 from
hole opening
When Main PCB is
installed (next step),
ensure the board
engages foam similar
to this view
Position foam about 3/8 in below
this edge
The MAIN PCB goes in next. Place the PCB on the PEMs in the chassis and slide the jacks
through the appropriate cutouts as shown. WHEN CORRECTLY INSTALLED THE JACK
FACES SHOULD PASS THEOUGH THE THOUGH HOLES. ENSURE THE RJ45
PROJECTS THOUGH ITS RESPECTIVE OPENING.
Begin by placing and partially tightening the (3) #6-32 x .375 lg. pan head Phillips screw w/
captive star lock washers (30-00-0607) that attach through the PCB. Tighten these screws only
partially. The back-panel screws MUST be tightened before locking these screws down.
Note: In spite of the warning, a screwdriver may be used to help insert the screws and partially
tighten them, but they must not be fully tightened until after the back panel screws are placed
and tightened. The “No Screwdrivers” graphic is simply to highlight this. The reasons for this
are detailed in the note at the end of this section.
Page 20 of 51
Vetta Head Assembly Instructions Rev D1
(4) #4 tapping screws (3000-4250) hold the XLR
jacks to the back panel.
Flush the jacks with the
back panel, insert the
screws, and tighten to 4
in-lbs.
(4) Plastic jack nuts
should be placed next.
Flush the jacks with the
back panel, insert the nuts,
and tighten to 4-5 in-lbs.
The PCB Screws must now be tightened the rest of the way. They should be tightened to a
torque of 6 in-lbs.
Note: These screws must be left loose until this step for 3 main reasons: (1) It is the easiest
way to get all of the screws to line up. (2) It will help prevent cracking in the solder joints
on the jacks and (3) it will ensure grounding points will make electrical contact with the
chassis.
FYI: If the PCB screws are tightened prior to inserting and tightening the back panel
screws, the fixed board may not align properly, creating high shear stress on the jack pins.
Conversely, if the PCB screws have not been placed and finger tightened to rough locate
the board prior to the back panel screws, there is a possibility of misalignment with the
PEMS. Forcing this misalignment back into alignment while the back panel screws are
tight will have the same effect of heightening shear stress on the jack pins and may crack
the solder joints.

Vetta Head Assembly Instructions Rev D1
e) Inspect the Completed Sub-Assembly
After completing the sub-assembly, inspect it to ensure that everything is correctly placed.
Check that:
•
•
•
•
•
Check that the power amp assembly is mounted in the correct orientation.
Check that the all PCB standoff holes have been secured (12 screws total).
Check that the power switch is snapped flush into the chassis in the correct
orientation.
Check that all screws and nuts securing the output jack have been installed
and are secure (4 screws, 8 plastic nuts).
Check that the RJ45 jack protrudes through the square hole in the chassis and
is flush with the back face of the chassis.
If the assembly passes the above tests, move on to the next step. Correct any problems
immediately. If you have any quality questions, consult your supervisor.

d) Inspect the UI PCBs
The UI PCBs should now be completed sub-assemblies. Check to make sure that:
1. All button assemblies are securely snapped in place and depress reliably. Ensure that
Rubber keypads sit naturally under the button frames and are not twisted or deformed
2. All soldered components are securely fixed to the PCB and are mechanically
functional.
• Visually inspect pots and encoders to see that parts are perpendicular to the board
surface. If the stem of a component is skewed, correct the problem immediately.
• Make sure all pots have nuts
• Make sure 3 out of the 4 pots in the right UI board are center click.
• Lightly pull on the stems of all potentiometers and encoders to ensure that the
component is properly fixed and that the part is not defective (i.e. the stem does not
detach from the component). If a component fails this test, DO NOT attempt to fix
the broken component. Discard and replace the component immediately.
• Spin the stem of each component to verify smooth consistent feel and function.
• Mark the PCBA with the appropriate Assembly Rev letter.
When inspection process is complete, set the front panel PCB sub-assembly aside.

e) Snap in Power Switch
Snap in the Power Switch to the rectangular hole indicated below. For correct mounting ensure
that the “O” symbol on the switch is oriented as indicated in the figure.
f) Inspect the Completed UI Panel Sub-Assembly
After completing the sub-assembly inspect it to ensure that everything is correctly placed.
Check that:
•
All knobs are uniformly seated and appear straight. If a knob is visibly skewed,
check for proper insertion and correct the problem immediately.
• Knobs turn smoothly and do not scrape the cover.
• Check that all knobs potentiometer knobs can turn to exactly the 12:00 position
• Pull on each knob until it starts to slide off the stem, then reposition it to its proper
height. This will help identify defective components. The knob must have the
ability to be removed without unseating the stem of its encoder or potentiometer.
• Check that the encoders have negligible wiggle (for missing or incorrect insertion
of the encoder shoulder washers).
• Check that all keycap assemblies have been mounted correctly in the up orientation.
• Test the buttons to ensure that they all have a uniform feel and are not pinched
under the cover. All buttons should depress and pop up freely.
• Re-examine the front panel for cosmetic defects. Look for any marks, scratches or
blemishes. Check for smudges or other defects in the silk-screening.
If the assembly passes the above tests, move on to the next step. Correct any problems
immediately. If you have any quality questions, consult your supervisor.

Cable Assemblies
a) Connect the Cable Assemblies
Before securing the completed chassis cover assy to the completed chassis assy, all cables need
to be connected. Use the table below to reference where the cables connect. The photos
following the table in this section reference the cables listed below. Use the table and photos
together to correctly complete this section.
Due to the very repetitive nature of this section, it will be very short on text. Keep the
following things in mind while connecting the cable assemblies:
• Connect all cable assemblies securely.
• Connectors should be fully engaged with PCB header shrouds.
• Some headers on the PCB’s will not be used and will be left empty.

b) Attach the Line 6 Logo
Peel off the backing from the logo piece (30-60-0002) to reveal the pressure sensitive adhesive,
center the logo in the bracket depression, and firmly press the logo into place.
c) Insert the Chassis into the Cabinet.
Before mounting the chassis into the cabinet, punch through the vinyl into the pre-drilled holes
in the chassis base. Approximate location for the holes is shown below.
Slide the completed chassis assembly into the cabinet unit the overlay on chassis cover sits
against the inside face of the front cover. Secure the chassis using 4 #10 (30-00-1124) screws
mounted with 4 #10 finish washers (30-03-0011).

The chassis will sit directly against back of the
cabinet front face when correctly installed.
Secure the chassis using 4
#10 (30-00-1124) screws
mounted with 4 #10 finish
washers (30-03-0011).
d) Place the Bezel Lenses
The bezel lenses must be placed next. The LCD bezels each have a smoked lens that attaches
with pressure sensitive adhesive. Gloves must be worn at this stage. Remove the adhesive
protection film. Carefully center the lens, and firmly press it into place.
Make sure that the
lenses are centered in
the bezels, that they are
undamaged, and that
they do not have any
fingerprints on them.

e) Attach the Knobs
The next step in assembling the cover sub-assembly is placing the knobs on the component
stems. The knobs are standardized across multiple Line 6 products.
The large encoder knob also has a spacing finger. DO NOT REMOVE the spacing finger from
the encoder knob (30-27-0027).
Check to ensure that the small encoder knob has been chosen correctly. It must NOT have a
white indicator line that shows its orientation. (Line 6 stocks a very similar small potentiometer
knob that has a line).
30-27-0024
30-27-0027
30-45-2000
30-27-0025
Simply orient the knob such that the D-shaped hole matches the stem of a component and slide
it down until it rests on the step in the component shaft. The knobs are not to bottom out on the
face of the product or the knob treatments.
Large Encoder pot shafts have a strip of tape applied,
from the Flat surface, across the top. (Not shown here).

Test and Inspect the Completed Unit
To help ensure maximum quality of all products, it is the responsibility of the assembler to
complete a post assembly inspection prior to sending the unit on to electrical testing and final
inspection. This should help achieve one goal: no unit shall ever be returned from test and
inspection for rework because of a mechanical defect that could have been corrected at the
assembly stage. Remember that things that have already been inspected during assembly may
have been inadvertently damaged during the assembly process. With this in mind, fully inspect
the unit for mechanical defects. Things to look for include:
• Cosmetic damage to any visible surface of the unit. This includes but is not limited to:
defects to the silk-screening – both front and back panel, dents, dings or scratches in all
outer surfaces, smooth even surface color of the front panel, even paint coverage and
texture to the top cover, scratched or fingerprinted lenses, scratches or fingerprints on
buttons, damage to button text or keycaps, and/or visible process marks on knobs and
other plastic parts.
•
Proper complete assembly of all parts. This includes but is not limited to: Presence of
all parts, flush full insertion of all screws. Even consistent spacing of knobs, proper
centering of lenses in cutouts, etc.
•
Proper mechanical function of all components. This includes re-testing all knobs for
smooth consistent feel, testing all buttons for proper feel.
•
Add stickers for inspection, serial number and AC voltage.
If there is any question about the quality of a unit, consult a supervisor for guidance. If the unit
passes assembly inspection, the unit is complete and ready to proceed to electrical testing, final
inspection, pack and ship.

Vetta and FBX Service Hints
If the PS_VALID line is inadvertently short-circuited, D15 on the power supply will
almost certainly fail. This will keep the audio from appearing on the Direct Outputs, and
possibly on the speaker outputs.
If the main FETs (Q3 & Q15) on the power supply are shorted, a series of components
will most likely fail. Replace R21, R7, R55, R49, R12, R11, R15, D4, Q3, Q15, Q11, Q2,
and U2.
If unit locks up intermittently and or settings aren’t remembered after power cycle, check
SRAM battery to ensure voltage isn’t significantly below 3V. Replace the battery if it is
below 2.7V and check the SRAM current consumption by measuring less than 100mV
across R185.
If 7 segment numeric display behaves erratically, check to ensure proper insulation
between pins and chassis on header connecting numeric display PCB to U.I. PCB.
If displays show garbled information or none at all, check to ensure proper seating of
ribbon cable from main board to U.I. board. Note: obvious but common.
Be extremely cautious when removing knobs for the three global controls. The shafts on
these pots will pull out easily. The suggested method is to hold the shaft of the pot from
the inside of the chassis with pliers while pulling the knob off. If the shaft breaks, the pot
CAN be replaced without removing the entire U.I. board. The method is to first cut the
pins of the pot, remove it and then de-solder and remove the pins remaining in the board.
If the power supply must be removed from the unit, it is not necessary to remove the
speaker output PCB. There is a hole in this board, which allows for accessing the power
amp screw below. A magnetic screwdriver is handy to put the screw back in.
Be very careful while working on the power supply PCB. The PCB section between the
AC receptacle and the transformer has high voltages.
Notice that the power connectors have a lever, which must be pressed to unplug them.
Also while pulling or pushing on these connector, try to support the PCB with the other
hand to avoid excessive stress.
Both power connectors on the speaker output board are 4 pin wide. The PCB screening
shows which one plug where.
Vetta and FBX Service Hints

If the DC bias voltage at the input pin 25, 24, 4, or 5 of the guitar input ADC U19 is
significantly off from its nominal value of 2.5V (less than 1.8V or more than 3.2V), the
part is probably bad. The same is true for Pin 22,23, 20 or 21 of the DAC U20 and U21,
and for pin 17,16,20,19,23,24,26, or 25 of the CODEC U16.
When troubleshooting the amp PCB by itself, you can power just the +/-15V rails and
check almost the entire audio path. Once that is checked then bring up the main rails and
check to see if the proper bias rails are all correct. This process allows for easier
troubleshooting before applying the high voltage rails.
If the software locks up when changing amp models, either the battery is not working or
dead, or the Model Defaults are bad. Model Defaults are loaded via MIDI SysEx from
the Save pages, and can be loaded from a working amp or from a MIDI SysEx computer
program.

Vetta Software Upgrade Procedure
The Vetta’s software is upgraded via a Midi SysEx data dump to the Vetta’s
Flash memory; there is no replaceable EPROM. To perform an upgrade to
Vetta, you will need either a Midi data filer or a computer with Midi SysEx
software as well as the new software code and a standard Midi cable (or
joystick-to-midi cable). New code can also be imported from another Vetta.
Connect the midi cable from the Midi out port of your transmitting device to
the Vetta’s MIDI In port (If your computer has a soundcard that utilizes the
joystick port for midi operations, you will need a Midi-to-joystick cable.)
After the midi connections are made and the unit from which you are
transmitting the software is ready with the proper code, follow the
instructions below.
(Note: To find the current software version in the Vetta, press System
Setup and turn the PAGE knob clockwise to the last page. The right display
should read “V e t t a Version 1.0x”, denoting the current software
version.)
1. Turn Vetta’s power button on while holding down COMP. The right
LCD will display “Software Update…Press EDIT to continue. Press TAP to
cancel”
2.Press EDIT to enter software update mode or TAP to exit update mode.
3.The right LCD will say “WARNING!! This cannot be undone! Are you
sure? Press SAVE to continue. Press TAP to Cancel”. Press Save to
proceed. The amp will now erase the current operating system software
from its memory. Please note: if you exit the procedure now and try to use
the amp, it will light up but the amp will not function as there is no operating
software.
4. After the amp has cleared out the old software, the right display will read
“Ready for Software Download”. Tell your Midi Data filer, Computer Midi
SysEx software or 2nd Vetta to send the new Vetta Operating system
software. (To send the software out of the 2nd Vetta, you must go into the
self test mode. To do this, power up the 2nd Vetta while holding down it’s
REVERB button. Proceed to TEST #13, “Upload Code”. Press COMP to
begin sending the software).
5. After amp has received the new software, the right display will read
“Software download complete. Press SAVE to run new software”
6. Press SAVE and the Vetta will go into play mode.
7. If program load is slow switching from channel to channel, you will need
to reset the program memory. Press SAVE and scroll to page 10, "RESET
FACTORY". Press SAVE while on this page to reset the Factory Bank.
The right LCD will read "…restoring FACTORY bank…". When this
process is complete, scroll to page 11, "RESET USER" and press SAVE
once again. The right LCD will now read "…restoring USER bank…".
Press TAP when the process is complete.
