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. -
Page 4: Mains Connections
Collecting electrical and electronic equipment and waste prevents the potential contamination of nature with the hazardous substances which may be present in electrical and electronic products and equipment. Your MANLEY or LANGEVIN retailer will assist with and advise you of the correct method of disposal in your country. -

3. On a rectangular chassis it is easy to specify front, back, sides etc - but on the 6 sided Stingray II we should adopt a convention and refer to the sides that have the RCA inputs as Left-Back and Right-Back. We provide 3 left inputs on the Left-Back, 3 right inputs on the Right-Back, and a 1/8”... -

A) Input Selection & Menu Control: This knob displays and allows the selection of any one of the 4 inputs available on your Stingray II. The LEDs show which input is selected, starting at the 9:00 position for Input 1 and ending at the 12:00 position for Input 4 (1/8”... -

You can also use this output to drive another preamplifier in another room, for instance. Or if you wish to use another preamplifier instead of the one built into the Stingray II, you can drive it here and run its outputs back into the Loop return. - Page 8 Remember this is a LINE LEVEL output, not a speaker output. If your subwoofer only has speaker level inputs on it, then you need to drive it with the speaker outputs on the Stingray II. Use of the headphone jack mutes this output.

You can also use this button to RESTORE DEFAULT SET- TINGS if you get lost in menus or just feel the need to reset your Stingray II to factory settings. To do this, just turn off power to the unit with the back-panel power switch. -

Display Menu Functions The Display Menu is the second of the two Menus on the Stingray II. To access the Display Menu, press both the Input Selection and Volume/Balance knobs at the same time. When all three red LEDs (Insert, RF, & IR) on the Input Selection knob illuminate, release the knobs. -
Page 11: Optimizing Your Sound System
If you are getting this amazing imaging and soundstage, you may be interested to know why you suddenly have it now that you have the Stingray II. These are very audible effects that seem to be beyond normal measure- ment technique or textbook electronic theory. This effect is directly related to the amount of negative feedback used in a design. - Page 12 You may have bought a great system but there is a good chance that you are only getting a fraction of its po- tential. Very frequently we have experienced top quality electronics sounding unimpressive simply because acous- tics were ignored. Even amongst studio engineers, few can really tell the difference between good speakers in a bad room and bad speakers in a good room - but they all know good speakers in a good room and very likely so do you.

In general we do recommend if you aren’t using the gear for more than a few hours you should power it down, or in the case of your Stingray II just put it in “Standby” mode with the little blue button on... -

What tools do I need? Just two. A small flat screwdriver (insulated handle) to adjust the trimmers. You also need a voltmeter or multi-meter, one of which we’ve provided with your new Stingray II. How convenient! Any multim- eter will do; it doesn’t have to be a good one. RadioShack sells them as well, if you want to purchase a different one... - Page 15 What do I do? The amp should be well warmed up (30 min.) and no music playing. Set the meter to read DC volts. The meter has two test leads, red and black. Put the black lead in the black terminal on the top marked TPG (ground) or touch the metal point to the steel chassis (but not a painted or anodized part).

Page 16: Remote Control
Your Stingray II is equipped with a Remote Control that communicates with the amplifier via RF (radio frequency) and/or IR (infrared) signals. In the Stingray II’s Menu Mode, you can alter these transmission settings (to learn how to do that, see page 9). -

HISS - Usually one of the sources. This source may have a volume control that is turned down and forcing you to turn up the volume of the Stingray II. Adjust the source so that it is a similar volume as your other sources. If it seems to be the one channel of the Stingray II, then it is probably an input tube (12AT7WA). -
Page 18: Credits
It all began at the HI-FI ‘97 show. We find the protagonists of this tale seated comfortably at the bar, of course - J. Gordon Holt with his traditional martini, and EveAnna Manley with her stimulant of choice, a cup of coffee. She was describing a new integrated amplifier she wanted to build, and proceeded to make one of those legendary “bar-napkin drawings”. -
