INTRODUCTION
THANK YOU!…
for choosing the Manley Stingray II integrated amplifier for your loudspeaker driving requirements. You possibly
chose this product because you auditioned it in a store or heard it at a hifi show and were impressed with the sound.
It may have been the right combination of price, power, features and styling for you. It may have been because you
know the Manley Labs reputation for quality, reliability, and integrity. If any or all of these were the reasons, you
made a good choice and for that, we thank you.
The Stingray II is the next step up the ladder of evolution from our acclaimed Stingray Integrated Amplifier, which
has had a strong presence in the hifi industry since it swam from our labs in 1997. Originally designed with the idea of
“two monoblocks in one chassis”, the Stingray quickly became one of our best-selling products. Its passive preampli-
fier delivers near absolute transparancy, no added noise, and extreme signal path simplicity. This preamp is essentially
coupled with a pair of 50 Watt monoblocks, which include custom-designed output transformers and an “overkill”
power supply that keeps immense amounts of energy stored so your system’s dynamic range and performance are
never lacking. In addition to “beefing up” the power supply for the Stingray II, we have added digitally controlled
volume, balance, input switching, a headphone jack, and a separate 1/8” stereo auxilliary input. All added features are
accessible via the front panel as well as with the included REMOTE CONTROL! We’re finally catching up with the
21st century...or maybe just the 20th...
This product shares the same philosophies and standards of component quality and build technique as all of the recent
Manley products. It uses the best available parts with the shortest, cleanest signal path possible. Visually, this product
is unique, elegant, and practical. Visual beauty may be a prime factor for some but the size, shape and component
locations were chosen first for performance reasons.
Please take a few moments to read through this manual; there may be features and information about this unit which
you should familiarize yourself with.
Thank you again, and please enjoy!
GENERAL NOTES
LOCATION AND VENTILATION: The Stingray II should be installed on a stable location with ample ventilation
to allow some cooling. A table top or cabinet top is a good choice. A speaker top is not the best location because the
vibration can transfer to the Stingray II and degrade the sound and possibly cause the tubes to become microphonic.
If your household has small children, we suggest that the Stingray II be in a location where it may be out of reach.
Similar considerations should apply if you have pets. You do not want the cat or dog jumping up on it or across it or
possibly exposing them to hot tubes accidentally. This unit is meant for indoor use and should be kept clean and dry.
You will probably need occasional access to the sides and back so placing this unit inside a 3-sided cabinet may be not
practical. If the Stingray II is placed on top of other equipment, we suggest that rubber feet or pads be placed under the
Stingray II’s feet to prevent scratching the surface of the other gear. Pennies work just fine for this too.
WATER & MOISTURE: As with any electrical equipment, this unit should not be used near water or moisture.
SERVICING: The user should not attempt to service the amplifier beyond that described in the owner’s manual.
Refer all servicing other than tube or fuse replacement to Manley Laboratories.
