INTRODUCTION
THANK YOU!...
for choosing the Manley Laboratories the "STINGRAY" INTEGRATED AMPLIFIER, You have
possibly chosen this product because you auditioned it in a store or heard it at a hi-fi 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 the right choice.
The basis of the STINGRAY is the Manley 50 Watt Monoblocks combined with what is generally
referred to as a passive preamp. We have always felt that the 50 Watt Monoblocks are among our best
amplifiers for sweet highs and three dimensional staging and imaging. We went a step further and
refined all performance aspects of the output transformers. The advantages of a passive preamp are well
known - near absolute transparency, no added noise and extreme signal path simplicity.
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 first 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 & VENTILATION
The STINGRAY 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 and degrade the sound and possibly cause the tubes to become microphonic.
If your household has small children, we suggest that the STINGRAY 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 accidently. This unit is meant for
indoor use and should be kept clean and dry. You will probably need access to the sides and back so
locating this unit inside a 3 sided cabinet may be not practical. If the Stingray is placed on top of other
equipment, we suggest that rubber feet or pads be placed under the Stingray's 3 feet to prevent scratching
the surface of the other gear.
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.
