Qv2 AC LINE HARMONIZER
The QVIBE, Qv2 is an AC Line Harmonizer that is designed to enhance the musical performance and picture quality of any audio or video system, delivering readily demonstrable benefits at an incredibly affordable price. It can be used as a “stand alone” product or to complement a full QRT system including QBASE-Mark II, Qx4, Qx2 and Qk1 units. The Qv2 works directly on the AC line, introducing a carefully calculated range of pulsed frequencies, clocked from the original 50 or 60Hz waveform. The result is a drop in noise floor, with a commensurate increase in image depth, dimensionality and presence, significantly increasing the realism of both musical and visual performance.
Like other QRT products, the benefits are cumulative and Qv2s are even more impressive when used en masse. The compact, “plug-top” construction of the Qv2’s mechanically tuned housing allows it to be inserted into any free socket on your system’s AC line – although adding directly to a QBASE-Mark II maximizes the benefits.
Qv2 units are available in either US (NEMA) or EU (Schuko) configurations, and compatible with 50/60Hz 100 – 240V supplies. However, standard adaptors can be used to employ the Qv2 in other markets. The Qv2 is housed in a mechanically tuned carbon fiber and has high quality gold plated connection pins. It is built entirely in the USA and carries a two-year warranty.
• Works directly on the AC line, actively introducing a precise range of pulsed frequencies
• Increases the depth and realism of the musical performance.
• Lower perceived background noise.
• Deeper, more dimensional and more vibrant picture on AV systems.
• Mechanically tuned carbon-fiber body
• Gold-plated NEMA or Schuko connector
The Aavik P-300 features a unique 150 W efficient Class A, non-switching output section where the bipolar output devices never stop conducting current. This means that the amplifier circuitry never has to deal with residuals such as switching spikes and device latchings.
The Aavik P-300 has an ultra short and simple signal circuit design, where all gain and feedback is performed by a single transistor pair. This short signal path gives the Aavik P-300 a unique gain structure with extremely low distortion and a more than 90-degree phase margin for absolute amplifier stability.
The Aavik P-300 has four 600 W power factor corrected resonant mode power supplies. The in total 2400 W power supply combined with the extremely large electrolytic power banks allow the Aavik P-300 to deliver peak currents in excess of 80 A.
Full Featured Control Amplifier
The C-300 is equipped with two built-in DACs (PCM and DSD) and a phono section. It also comes with three line inputs: two single-ended and one balanced, and an RCA and an XLR output.
The Aavik C-300 RIAA section is based on a discreet, floating, balanced, ultra-low noise, bipolar input circuit. By nature, the topology of a moving coil cartridge is a floating, balanced signal generator. We have kept this floating, balanced circuit topology throughout the phono stage. The floating input circuitry allows us to use ultra-low noise, bipolar transistors. By paralleling several transistor pairs, we have created a dead-quiet input section. The Aavik C-300 phono stage has a 62 dB gain, and the cartridge loading is adjustable from 50 ohm to 5 kOhm.
The phono section of the Aavik C-300 will let you explore the amazing details and musical depths of your vinyl collection!
The Aavik C-300 is equipped with two DACs: one for PCM digital formats and one for DSD formats.
The Aavik C-300 PCM DAC section is designed around 5 digital inputs, which all excel in performance. The DAC performs without any digital signature, which makes any music sound “analog”. The digital circuits are created with the best high frequency skills tools available and great care was embedded in the PCB design. We made a lot of effort to ensure we have a 100% equal treatment of the differential signals, with time-aligned, ultra-short, 4-layer PCB traces. The DAC's circuits are fitted with ultra-low jitter onboard clocks in order to minimize timing errors in the digital-to-analog conversion. In the Aavik C-300 all DAC circuits are isolated with 13 onboard, separate low-noise, high-PSSR voltage regulators each feeding only one stage of the signal handling. The digital signals from the 5 digital inputs are routed to an ASRC, where they are resampled and re-clocked to 200 kHz/24 bit PCM, feeding current output DAC chips. The current-to-voltage conversion is performed with a differential floating topology with virtual GND. This isolates the signal path from the potential GND noise and signal induced GND modulation.
The Aavik C-300 DSD DAC section features a very simplistic gain structure with only one gain stage and a purely passive LC type analog filter, made from shielded coils and the highest quality capacitors available. The passive 6th order filter is placed at 60 kHz where it effectively removes all switching artefacts without adding excess noise in the audio-band. A pure and unique method of making the D to A conversion without passing the signal through any type of DAC chipset and software based noise shaping.
The 2 USB inputs are galvanic isolated to avoid noise pollution from the host. This isolates the signal path from the potential GND noise and signal induced GND modulation. The DSD USB input has signal priority over the PCM USB input. Whenever there is DSD signal present from the host the USB DSD input will be active.
Line Stage/Volume Control
The Aavik C-300 line stage uses a unique, inverted, virtual GND amplifier topology, which preserves the finest musical details on a dark, quiet, black background. The line stage has two inputs with 9 dB gain and one line input with 6 dB gain.
The volume control is realized with microprocessor-controlled resistor-ladder (R2R) circuit inside the feedback loop of a virtual GND amplification stage. The volume control regulates from -80 dB to 0 dB in approx. 1 dB steps.
