Manley Stingray II

The Stingray II integrated tube amplifier has a full-featured RF and IR remote control & built-in headphone amp.

The Stingray II is the next evolution of the acclaimed Stingray Integrated Amplifier. The Stingray II retains the same basic tube circuitry and marvelous output transformers as the original with some important improvements:

The high voltage tube energy storage has been increased vastly resulting in even more solid and coherent bass control and impact.
A headphone jack has been added to the right side facia. This jack re-routes the output from the speaker binding posts and mutes the Subwoofer output feed.
New remote control. The remote control works with both Radio Frequency (RF) and Infrared (IR) technoligies. Using the remote in RF mode gives freedom from having to “point and shoot.” The RF remote is omnidirectional and works through walls and cabinets. IR capability is included for those with Universal Learning Remote Controls for consolidated integration into existing systems. The volume control, balance adjust, and input switching are all on the RF/IR Remote Control. Additionally user can perform the MUTE, DIM, INSERT and SLEEP commands with the Remote Control.
Each INPUT can be individually level-trimmed to match and to optimize system gain staging of various input devices.
The blue LED displays surrounding the INPUT and VOLUME encoder knobs can be dimmed down or turned off entirely, after a user-settable time period, or a “screen-saver” random light sequence can be selected. Speed and intensity of the “Starlight” mode can be tweaked to taste.

All custom user settings are hard written into memory when the unit is put into STANDBY mode and thus retained if power is later interrupted.

Individual sealed gold contact relays deliver the selected input into the volume control system before hitting the first 12AT7 input tubes. Following the 6414 driver/phase splitter, the trusty EL84 output stage can be switched between either around 20 watts of TRIODE power or 40 watts of Ultra Linear mode push-pull operation. Individual bias for each tube is easily adjusted using the trimpots and test points, conveniently located on the top surface of the amplifier. The Stingray’s power supply is extra-rugged and stiff, a MANLEY hallmark. It swims with the sharks: fast, agile, fluid, and with consummate authority.

SUBWOOFER OUTPUT allows easy hookup of outboard line-level driven active powered subwoofers. This output is after the volume control so that the subwoofer will track the volume level changes of the main speakers. The SUB OUTPUT is a line level and full frequency output that is AFTER the volume control so your powered subwoofer follows the same volume as your main speakers. These are unbalanced RCA jacks, line level. They feed the line inputs of your subwoofer, NOT the speaker jacks. A switchable TAPE LOOP is standard. The TAPE SEND is the output of the selected input before the volume control. The TAPE RETURN can also be used as a 5th line input if needed.

RECORD OUT (aka Tape OUT) is BEFORE the volume control so you can record whatever input you have selected without your listening level affecting the level going to your recorder. These are unbalanced RCA’s. It is UNbalanced RCA’s and UNbuffered so check out the input Z to your recorder to make sure it won’t load down the Stingray main input while it is plugged in. Usually with unbuffered record outs we recommend you only plug in your recorder only when you are actually recording…

TAPE LOOP: Also known as an INSERT point, the SEND or Tape Out comes off the selector switch as the Record Out option does going to your outboard EQ or Merlin BAM unit or tape recorder and then the signal returns (RETURN) to the Stingray in front of of the volume control so you can play tunes. A toggle switch selects whether the Tape LOOP (and whatever is plugged into the Tape Loop) is active or the signal goes straight through the Stingray as normal.
