LT-6P Stereo Control Tube Preamplifier

Audio signals at the source components are at their most delicate. It’s at this earliest stage where tube-type pre-amplification seems to best preserve the signal’s integrity.
The Wright Audio LT-6P not only maintains signal integrity but also allows for Bass and Treble adjustment due to the wide variety of tonal balances in today’s digital component and internet sources as well as the past’s analog vinyl recordings.
The carefully-implemented Bass and Treble Controls in this preamplifier are passive. Other than the controls themselves and very few associated passive parts, there are no other devices in the signal path. They work in the more extreme ends of the frequency spectrum without negative effects in the midrange.
This approach is unlike traditional ‘active’ feedback-type controls which require an additional amplification stage in the signal path and its associated distortions which have given many audiophiles reason to dislike these controls. The passive controls allow the tubes to operate in an improved, better-sounding gain range. This preamplifier actually sounds better than many which do not have them when the controls are set to the ‘Flat’ position.
The preamplifier uses a vacuum tube, filtered power supply operating at less than one-sixth of its capacity to maintain the purity of the signal. There are no solid-state devices in the preamplifier with the exception of the tube heaters’ power supply. Also, there are no circuit boards which allows for the possiblity of circuit and parts upgrades in the future with relative ease.
The capabilities of handling up to six inputs, two fixed-level outputs and two independently powered and isolated variable outputs provides maximum versatility for any installation. Yet installing and using the preamplifier is completely intuitive. With no displays requiring power, the front panel settings are visible from a few feet away even with the power off.
Although the LT-6P Preamplifier is electrically compatible with most solid-state power amplifiers, it is important to note that maximum benefit will be achieved when the LT-6P is paired with the electrically and sonically matched Royale SE Single-Ended Stereo Power Amplifier or a pair of the monaural Wright Audio Oasis Power Amplifiers.
As a set, they offer the dynamics, soundstage dimensionality, nuance and clarity which make listening to music the indescribable joy it should be.
FEATURES AND SPECIFICATIONS

  • Controls:
    Source Selector (CD, Tuner, Video, Line 1, Line 2, Line 3)
    Fixed Level Output Switch
    Main Stereo Volume Control
    Separate Left and Right Channel Volume Level Preset Controls enable channel balance.
    Bass, Treble Controls

  • Preamplifier accommodates any line-level device with an analog audio output except Phono.  Six inputs.

  • Passive Fixed Level Output Switch selects between two outputs for use with a stand-alone headphone amplifier, any type of wireless transmitter, recording device or similar.  ‘Off’ position isolates connected devices from each other and the preamplifier.  Preamplifier need not be powered on for this feature.

  • Two electrically isolated, but identical outputs for driving the power amplifier and a subwoofer system or other device.   Drives up to about 50 feet of low-capacitance cable into a minimum of 20K input impedance.

  • Individually-mounted, high quality RCA input and output jacks.

  • Custom Alps conductive plastic controls.

  • Tube complement: (2) ECC83 / 12AX7; (2) ECC81 / 12AT7 (1) GZ34 / 5AR4 rectifier.  Clear gray acrylic tube shields.

  • Heavy, one-eighth inch and .090 black hard-anodized aluminum panel construction with solid, dark oak side panels.

  • Overall Size:  17 1/2 W x 7 1/2 H x 13 1/2 D inches.  Allow three inches above unit for heat dissipation.

  • Vibration isolation feet.

  • Net Weight:  15 lbs.  Shipping Weight:  21 lbs.

  • THREE / FIVE YEAR WARRANTY with the exception of tubes.

  • For 120 Volts AC.  Detachable power cable.

  • Designed and assembled in the United States using U.S. and Global components.
