  Stingray Integrated Amplifier
Description

ALL 2007 MKII STINGRAY AMPLIFIERS ARE NOW SUPPLIED WITH THE FOLLOWING FEATURES INCLUDED AT NO EXTRA COST;

  • Triode UL Switching
  • SUB WOOFER OUT
  • RECORD OUT & TAPE LOOP OUT (with bypass switch)

Initial concepts for the Stingray came to fruition during the US HiFi '97 convention. This wonderful chassis design was the result of careful research into optimal component placement to achieve purity and symmetry in a signal path layout. The idea, in essence, to produce a competitively priced unit capable of reproducing the rich midrange and silky top end of vintage designs whilst combining them with a driving low frequency register previously achieved only with their larger amplifiers.

The key to realizing this all-encompassing, driving spirit would be found in a new output transformer design which Manley's "Hutch" Hutchison and Michael Hunter set upon with enthusiasm. Armed with an extensive technical library and in-house transformer winding facilities, they returned to more traditional thinking, adding some clever twists at the end. Measuring listening testing and tuning led to a decision to replace a venerable 15 year old input stage with an innovative and fresh contribution from fellow engineer Paul Fargo.

Separate left and right silver-contact select switches (for the four stereo line inputs) deliver your music into the premium Noble® balance and volume controls before hitting the first 12AT7WA input tubes. The advantages of a passive preamp driving an extremely short and low capacitance cable are well known:transparency, no added noise, and extreme signal path simplicity.

Following the mighty 6414 driver/phase splitter, a trusty EL84 output stage can be factory strapped for either 25 watts of TRIODE or 50 watts of Ultra Linear mode push-pull operation. (UL Mode is the Standard Configuration.) Individual bias for each tube is easily adjusted using the trimpots and test points, conveniently located on the top surface of the amplifier. (there is even a meter supplied with each unit to allow easy set-ups) The Stingray's power supply is rugged, stiff and designed to last.

The MANLEY team have struck a remarkably harmonious balance in design which satisfies the sonic desires of audiophiles and rockers alike, the artist and the musician, the student and the master. Unique in design and performance, The Manley Stingray.

Subwoofer OUT is AFTER the volume control so any powered subwoofer follows the same volume as your main speakers. Connection via unbalanced phono/RCA point.

RECORD OUT is BEFORE the volume control so you can record whichever input source is selected without affecting listening levels or overloading your recorder. Again, these are unbalanced phono/RCA.

Unfortunately there is no room on this unit for a phono input....
