The Sphinx Myth 11 design

This service manual will help you to optimally
service and repair the Sphinx Myth 11 Stereo
Power Amplifier.

This high quality high end stereo power amp is of
discrete design throughout (no IC's are used).

The power amp uses specially selected Power
MOS-FETs with a power bandwidth of over 20 MHz,
a very fast slew rate and an unsurpassed phase
linearity over the power bandwidth. Each channel
uses four 120W/10 A FETs, operates as a pure
voltage source with an extremely low impedance
and is thus very stable.
The most unique feature is that it works in full
Class-A mode up to 10 W!
Thanks to the generous energy reserve of 69,600
µF, unlimited power is available for the largest
signal peaks.

To obtain the maximum quality from this power amp
it is necessary to use it with top quality audio
components, preferably with other Sphinx
components.

1. UNPACKING

Before leaving the factory every Myth 11 is
subjected to stringent and extensive technical and
exterior quality inspection.
This ensures you will enjoy many years of high
quality audio from a perfect-looking product.

Attention: The power amp weighs over 10 kg!
Never lift it out of the box without someone
helping you.

After unpacking your Myth 11 we therefore
recommend you carefully check it for any transport
damage.

Even if the component is in perfect condition you
should still keep the packing materials. If you need
to transport your Myth 11 at a later time it will be
best protected by the original packing materials.

2. CONTACTING THE MANUFACTURER

In case of any problem not covered in this manual
or if you have other questions you may contact the
Sphinx International Service Department in The
Netherlands (local time: GMT +1h) during office
hours at the following numbers:

Phone: [phone]
Fax: [phone]
E-mail: [e-mail]

It is always very helpful and efficient if you have all
relevant information about the specific product and
the problem ready.

Please also refer to the User Manual of the
Myth 11 for information about functions not
described in this manual.
It is important to familiarise yourself with the
special functions, operation and possibilities
of the Sphinx Myth 11.

4. OPERATION

Once you have finished connecting all components,
you can switch on the Myth 11.

Connect the mains cable to a mains outlet.

Power on

Switch the Myth 11 on with the O / I switch (7) on the
rear panel.

The STANDBY LED (3) will blink for a while after
which it will light red. The Myth 11 is now in stand-by
mode.

From now on you should switch the power amp on
and off with the STANDBY button (1) on the front
panel or the STANDBY button of another Sphinx
component connected to the optical CONTROL IN
jack.
This way all circuits will remain at working
temperature and the audio quality will be 100 %
within 15 minutes after activating. Additionally it
considerably increases the life span of the
component.

Switch the Myth 11 on with the STANDBY button:
the LED (3) will extinguish and the POWER LED (2)
will light.

If you activate the power amp for the first time or
after a long period of non-use with the power 'off',
the amp will be at maximum performance after one
hour.
From stand-by mode it takes only around 15
minutes.

Power off

You switch the Myth 11 off (stand-by) with the
STANDBY button (1).

N.B.: If you need to switch the system on again
immediately, you should wait for at least 60 sec
though.
Because switching on the amp within 30 sec will
activate the protection circuits: the red PROTECT
LED (4) will blink rapidly.

Only if you will not be using the amp for a long
period (e.g. during holidays) should you switch the
amp off with the O / I switch (7).
In stand-by mode the Myth 11's power consumption
is still around the 70 W mark.

6. ADJUSTMENT PROCEDURES

The Myth 11 only has three parameters for each
channel (so six in total) that might need adjustment:

- Bias: to set the bias current and bias voltage of
the amplifier for normal use.

- Offset: to set the DC-offset voltage of the
output.

These adjustments might be necessary when the
amplifier has been used for a period of time (and
settings have changed due to ageing) or when parts
of the Myth 11 have been replaced.

Attention:

When re-adjusting any setting please ensure that
there is no loudspeaker connected to the output!
Otherwise the loudspeaker may be seriously
damaged.

Attention:

The amplifier is able to generate high output
voltages of over + or -40 V.
Please be very careful during the adjustments!

Bias

With this procedure you set the proper bias level for
the power FETs. This ensures their Class A
operation at low power levels.
Connect the amplifier according to the drawing
“Measurement Set-up” (page 11).
The input of the amplifier must be shorted (by way
of the MUTE function of the oscillator).

• Switch the amplifier ON and wait until it has

reached the proper working temperature

• Set the millivolt-meter to the DC-range.

• Place the two measuring clips of the meter

across one of the source resistors
Left: R30L, R31L, R39L, R40L
Right: R30R, R31R, R39R, R40R

• The level for each should be 8 mV DC (±2 mV).

If not: adjust potmeter P2L (Left) or potmeter
P2R (Right) until the level is 8 mV.

• Repeat this procedure after 20 minutes to

finalise the adjustment.

• Switch the oscillator on and set it to 1 kHz and a

level of 0 dBV (1 V).

• Check the distortion with a THD analyser: it

should be conform to the specified value
(0.006% IHF-A @ 1 – 20 kHz @ 50 W into 8
ohm).

If this is correct the procedure is finished.
You may now switch off the amplifier or continue
with another adjustment procedure.

Offset

The Offset adjustment procedure minimises the DC
offset value of the amplifier output. This DC offset is
important when capacitive loads are used, such as
electrostatic loudspeakers. These loudspeakers
often use a very low-impedance step-up
transformer. The amplifier ‘sees’ this load as a
short for the DC voltage.

Connect the amplifier according to the drawing
“Measurement Set-up” (page 11).
The input of the amplifier must be shorted (by way
of the MUTE function of the oscillator).

• Switch the amplifier ON and wait until it has
reached the proper working temperature.

• Set the millivolt-meter to the DC-range.

• Place the measurement clips of the meter over

the output terminal.

• The level should not exceed +1 or -1 mV DC.
If it does: adjust potmeter P1L (Left) or P1R
(Right) until the level is within this range.

• Repeat this procedure after 20 minutes to
finalise the adjustment.

• Switch the oscillator on and set it to 1 kHz and a
level of 0 dBV (1 V).

• Check the distortion with a THD analyser: it
should be conform to the specified value
(0.006% IHF-A @ 1 – 20 kHz @ 50 W into 8
ohm).
If this is correct the procedure is finished.

You may now switch off the amplifier or continue
with another adjustment procedure.
