Preamp Focusrite ISA One
Preamp Focusrite ISA One - Analogue, bộ khuếch đại âm thanh.
- Preamp Focusrite ISA One ISA One tích hợp DI và hiệu chỉnh trở kháng đầu vào cho phép sử dụng cho micro thu vocal, capinet và guitar điện. Khả năng tinh chỉnh trở kháng là một thế mạnh của ISA One cho phép phát huy mạnh nhất các ưu điểm của các loại micro khác nhau.
- Các chức năng khác như cắt tần số thấp 75Hz, đảo pha, lọc tần số cao.
- Chức năng kiểm soát tín hiệu bằng đen LED và đèn Analog cho cả đầu vào và đầu ra
- Cho phép insert tín hiệu hoặc bộ xử lý ngoài như compressor, tích hợp headphone để kiểm tra mức tín hiệu.
Featuring a rugged, portable all-metal enclosure, ISA One combines the classic Focusrite microphone preamp with a flexible, independent DI channel and optional 192kHz precision A-D conversion. At the heart of the ISA range is the microphone preamplifier with its Lundahl input transformer – essentially the same circuit, based on the original ISA 110, that has been used for 30 years in successive Focusrite designs. The input transformer imparts a special character to the sound that can't be truly emulated in any other way, while the modern twist of variable input impedance allows for a new degree of flexibility.
Whether you're an artist, engineer or producer, you'll appreciate the versatility of the ISA One, with its front-panel DI input. The DI includes low/high impedance switching and an amplifier output, and its own feed to the optional A-D converter and separate rear-panel XLR output.

    METERS

    Moving Coil (MC) Meter factory calibrated to 0VU = +4dBu with 1kHz sinewave. With the VU Cal button pressed the meter can be adjusted on the rear panel to allow 0VU to equal +10dBu to +26dBu with the centre detent being equal to +22dBu.
    Peak LED Meters Calibrated in the detent position for 0dBFS = +22dBu, calibration is adjustable on the rear panel to allow 0dBFS to equal +10dBu to +26dBu
    Routing for MC and Peak1 meter is after the HPF, pre insert send or switched post insert return. Peak2 is always pre ADC channel 2, which can be fed by external input or Instrument input.
    LED Levels As follows, when peak calibration is set to center detent on the rear panel. (This is when using the internal ADC). 0 = +22dBu
    -2 = +20dBu
    -6 = +16dBu
    -12 = +10dBu
    -18 = +4dBu
    -42 = -20dBu
    Frequency Response At minimum gain (+10 dB) -10dB input: 10Hz-100kHz +/- 0.6dB
      At maximum gain (+40 dB) -40dB input: -2.5dB down at 10Hz and 0dB at 100kHz
