The Fosgate Signature embodies unique and patented circuit topologies, elevating the headphone listening experience. The genesis of the design started over 2 decades ago. Countless man-hours of working with every possible major circuit approach was not just explored, but designed, built, and auditioned by Jim Fosgate himself. Some initial designs used output transformers, some designs were direct drive with no output transformer. Others prototypes used solid-state circuitry and buffers to obtain low output impedance for driving headphones. Through this painstaking and thorough approach, a headphone amplifier design evolved which satisfied the exacting standards of Jim Fosgate.\u003cbr\u003e\u003cbr\u003e\n\nThe chose circuit incorporates 12AX7 vacuum tube amplification in the low distortion SRPP configuration, similar to our Signature Vacuum Tube Phono Preamplifier, winner of the 2011 Golden Ear Award from The Absolute Sound magazine. High speed, high current, video buffers are used to drive headphones directly. This provides a pure audio path with low output impedance, low distortion, and wide signal bandwidth.\u003cbr\u003e\u003cbr\u003e\n\nThe Video Buffers are not Op Amps and have no voltage gain. They offer high impedance inputs so the vacuum tubes are not loaded down, and low output impedance capable of driving most headphones to high volume levels with no audible distortion or colorations. The natural smooth sound of the 12AX7 vacuum tubes pass straight through to the outputs.\u003cbr\u003e\u003cbr\u003e\n\nThe bass boost equalizer circuit is designed to give the headphone listener defined, low frequency bass impact without bass boom. There are three positions on the bass control, Min, Max, and Off. When the control is in the center Off position, the bass boost is bypassed. This circuit has been used in different forms in many products including Rockford Fosgate Car amplifiers. Jim Fosgate received US patent number 3,883,832 for this circuit in 1975. It is called a “SINGLE ELEMENT CONTROLLED TWIN T FILTER” and has a much steeper curve then a bass or loudness control. It changes frequency and amplitude (Boost) with a single control. When the control is set in the Min position, the maximum boost is applied at a lower frequency then when the control is set to the Max position.\u003cbr\u003e\u003cbr\u003e\n\nAll aspects of the circuitry maximize a clean signal path. However, the uniqueness of the circuit does not end here. In order to infuse the sound with a natural sound stage, Jim integrated his surround circuitry design, part of his US patent 5,307,415 “Panorama Control” filed in April 1994. This circuit applies an out of phase cross blend to create a sense of depth and space and moves the dimensional soundstage outside of your head. The control has Min, Max, and Off positions. In the center off position the surround circuit is bypassed so the signal is unaffected and provides normal stereo.\u003cbr\u003e\u003cbr\u003e\n\nThis Headphone Amplifier’s elegant circuit has the tube amplifiers, buffers, bass EQ, and surround processing configured in a single stage. Negative feedback is applied around this stage in a single loop. Output offset is controlled with DC servos, allowing the video buffers to directly drive the headphones with no output capacitors in the signal path. There is only one coupling capacitor per channel in the signal path, and it is enclosed within the feedback loop, thus capacitor colorations are eliminated. Distortion and noise are below the threshold of hearing. The bandwidth is very wide allowing audio signals to pass through without colorations. Bandwidth is an amazing “ten times” the threshold of human hearing, 2 HZ to 200KHZ at -3DB.\u003cbr\u003e\u003cbr\u003e\n\nThe power supply is similar to the one used in the Fosgate Signature Phono Preamplifier. It uses separate oversize storage capacitors on each amplification path of each channel to provide a rock solid supply voltage without voltage regulators to affect the signal.

One is a 3.5mm stereo socket for the connection of earbuds and similar devices, which presents an output impedance of 2Ω to suit these devices. The other two sockets offer an exceptionally low impedance (around 3mΩ) and are standard 1\/4in stereo (tip-ring-sleeve) types, carrying both channels. They can be used to connect two pairs of headphones, or to attach a single pair of headphones wired with separate cords for left and right drivers, thus offering the opportunity to reduce headphone crosstalk.\u003cbr\u003e\u003cbr\u003e \n\nIn addition to simply replaying stereo audio at the highest possible quality via headphones, the outputs also include two “Analogue Spatial Processing” modes, i and ii, which replace the typical “in the head” experience of headphone listening with a smooth, natural feeling of spatiality that is much more like listening on a pair of loudspeakers in front of the listener. \u003cbr\u003e\u003cbr\u003e\n\nThe USB conversion system is powered from the interface, meaning that when it is disconnected, all digital circuitry in the unit is deactivated. The fully asynchronous USB 2.0 interface supports signals at up to 192kHz\/24-bit sampling and includes Meridian resolution enhancement techniques such as oversampling and Meridian’s unique Apodising filter. \u003cbr\u003e\u003cbr\u003e\n\nFilters are critical in digital audio. Commonly they introduce distortion and harshness because of \"pre-ringing\". Early digital recordings suffer from harshness too, due to primitive filters. After painstaking research, Meridian developed a special filter that avoids pre-ringing, so it can be steeper, cleaning up the effects of early filters. The result: a better, cleaner sound from recordings old and new. \u003cbr\u003e\u003cbr\u003e\n\nSourced from the original studio master recording as approved by the creative team, MQA combines an advanced new digital sampling technology that captures extremely high frequency timing and detail in an audio signal with an equally novel system to “encapsulate” that data into a form for delivery using any lossless file format or streaming. The listener’s decoder reconstructs the entire original signal, bringing up an indicator confirming that what they are hearing is exactly the same as the original master. Without the decoder, the listener enjoys CD quality reproduction. Its most advanced form, “MQA Studio”, uses the technology in the studio to generate an even higher quality master recording as the source. \u003cbr\u003e\u003cbr\u003e\n\nTechnical Specifications:-\u003cbr\u003e\nDESIGN: \u003cbr\u003e\nDespite its diminutive size, Meridian Prime echoes the design elements of any other Meridian product, including a double skinned, bead blasted metal chassis found on Meridian’s full size components.

The SH is a single-ended, two-stage full-valve headphone amplifier designed to accommodate traditional analogue and modern computer-based audio sources.\u003cbr\u003e\u003cbr\u003e\n\nThe SH began with the same basic remit as the coveted Simply Italy integrated amplifier; to produce a world-class sound from a specialised device using the best technology available. The result was a fairly simple, linear circuit that produces an output voltage which is more than capable of driving a wide range of headphones, while keeping distortion low throughout the frequency range. This allows the SH to deliver a consistent, coherent sound character when in use.\u003cbr\u003e\u003cbr\u003e\n\nThe input stage uses ECC83 valves, while the output stage uses one EL84 valve (both operating in triode mode). The benefits to using this specific combination of valves are in the reduced power requirements for how the valves are usually employed, resulting in extended life, and the EL84’s ability to drive an output transformer with optimal electrical and sound qualities. \u003cbr\u003e\u003cbr\u003e\n\nThe SH comes equipped with two headphone outputs, connected in parallel for easy switching between headphones, or to accommodate multiple listeners. There is also a “Sensitivity” switch, to ensure the widest possible range of headphones can be comfortably driven by this amplifier. When set to “High Sensitivity”, the output voltage from the amplifier is reduced, and at “Low Sensitivity” it is at its maximum. The added advantage of this switch is for maintaining optimal sound quality while listening to music at lower volumes.\u003cbr\u003e\u003cbr\u003e\n\nIn addition to a standard un-balanced RCA input for connecting any traditional analogue source, the SH is also equipped with a class-leading USB DAC. The asynchronous USB 2.0 technology is the same as found on the recent Triode 25 amplifier, and supports audio formats up to 384kHz PCM and DSD 128. The patented jitter-elimination circuit ensures a great sonic performance, assisted by the galvanic isolation employed between the power areas of the USB interface and the conversion IC. This additional input option brings SH up-to-date with the latest requirements of computer-based audiophiles.\u003cbr\u003e\u003cbr\u003e\n\nWith the use of an Apple lightning to USB connector (not included) you can plug your iPhone\/iPod\/iPad directly into the SH's DAC and play your hi-res music files straight from your device.\u003cbr\u003e\u003cbr\u003e\n\nThe reason for choosing a headphone-based product was so Unison Research could cater for the growing world of headphone audiophiles, offering them the best valve-based amplifier to enjoy.

Balanced output: Using a BTL (bridge-tied load) configuration, the balanced output combines the positive and negative signal outputs from four independent amplifier blocks. This setup enhances channel separation, positional accuracy, reduces intermodulation distortion and improves power regulation. Unbalanced output: The unbalanced output employs a parallel drive system, combining two amplifier circuits per channel to double the output current, ensuring ample driving power. When using the balanced output terminal (φ4.4mm or 4-pin XLR), a switch allows for parallel unbalanced operation with independent left and right grounds. For the ultimate headphone listening experience, connection to two P-100 CENTENNIAL units via their 3-pin XLR outputs offers parallel BTL balanced drive.
