Designed to capture audio at a level of quality that will satisfy even the most demanding professionals, OCTA-CAPTURE features VS Preamps on its eight analog inputs. Built with a Class A design for superb audio performance, these microphone preamps are based on those that have become a trusted part of Roland’s V-Mixer series of commercial digital consoles, as well as the V-STUDIO 700 high-end DAW system. VS Preamps feature a rich array of premium components that help maintain the purity and transparency of the sound, including radial capacitors designed specifically for audio applications. As a result, they achieve an astonishing input-equivalent noise level of -123 dB, among the very best in their class. Another characteristic of VS Preamps is their even balance of sound reproduction over the entire frequency range, from ultra lows to extreme highs. This lets you record sources with no unwanted coloring of the original sound. What is Class A circuitry? Amplifier circuitry is classified into different “classes” depending on the performance characteristics of its design. Class A distinguishes itself by utilizing 100% of the current flow in its linear range at all times. What this means to musicians is that this simple design ensures a stronger, hotter current draw with audio performance that tends to have more sonic detail and less distortion. Minimal analog circuitry reduces unwanted noise In order to achieve excellent sound quality, designers must simplify a circuit’s design as much as possible to prevent audio quality deterioration from undesirable signal-path routing. To this end, OCTA-CAPTURE’s design has eliminated as much analog circuitry as possible for controlling parameters such as input level, impedance, and phase reversal, as well as low-cut filters and compressors. All of these parameters are controlled digitally with the built-in DSP, reducing the amount of analog circuitry not related to amplification, and therefore minimizing unnecessary variations in sound. The LED level meter and peak indicator are controlled by the DSP as well; this is a great advantage, not only in terms of reducing the effects of analog circuitry on sound quality, but also in ensuring accurate meter readings.

Each board has its own power supply, which helps reduce noise and keeps crosstalk to a minimum. Needless to say, wiring runs have been significantly reduced. Independent of the analog input circuitry, OCTA-CAPTURE comes with a large-capacity power supply that is dedicated to supplying phantom power. This enables consistent recording performance, even when power must be supplied to eight microphones at once or when using mics that require large amounts of power. Large LCD with peak indicator Indicators flash when excessive input level occursPeak hold OCTA-CAPTURE’s front panel is equipped with a large, easily visible LCD with level meters. These meters allow you to make fine adjustments to your input levels, with a peak-hold function for checking peak levels on all channels at once. The Channel Select switch to the left of the LCD doubles as a peak lamp; it flashes red when any channel’s peak level is exceeded, allowing you to instantly recognize excessive input levels from a distance. Pro features for perfect multi-mic recordings With its eight mic preamps, OCTA-CAPTURE shows its mettle in multi-mic applications like recording drums or full bands. The input level specs for Channels 7 and 8 have been optimized for extremely dynamic sound sources with high peak levels such as kick drums; the extra headroom (up to +16dBu) available on these channels helps prevent clipping and other recording problems. OCTA-CAPTURE also features independent compressors on its eight analog inputs to control the dynamics of difficult sound sources, ensuring solid recordings with clear sound and consistent levels. +10dBuLevel exceededPrevious models+16dBuHeadroomOCTA-CAPTURE 2 Technology Overview AUTO-SENS automatically sets the input level for each channel Setting optimum recording levels is an indispensable part of capturing high-quality recordings. If input levels are too high, the sound will distort; if levels are too low, you lose the advantage of the excellent resolution afforded by digital recording, and the sound suffers from signal-to-noise ratio deterioration. To solve these issues, OCTA-CAPTURE is equipped with a newly developed “AUTO-SENS” function, which makes it quick and easy for even novice users to set the optimum level for a particular sound source. With AUTO-SENS, all you have to do is press a button, supply sound input, and the built-in DSP will analyze the s...
