Audient Sumo Summing Amplifer, First Take:

  • Balanced stereo mix bus as found in the best studio consoles and master compressor
  • 16 paired input channels with added flexibility
  • Expandable to 64 analog inputs
  • 24-bit/192kHz AES/EBU digital output card

    Balanced Stereo Mix
    The Sumo Summing Amplifier gives you a balanced stereo mix bus ” as found in only the best studio consoles ” the stereo master compressor from the acclaimed Audient ASP8024 recording console, a peak limiter, monitor controller and 192kHz digital output option. Separate gain reduction metering is provided for each processor, giving instant visual feedback. Metering is accomplished through a 26-segment meter, ranging from --36 to +24 dB (-60 to 0dBFS).

    16 Paired Input Channels
    Sumo offers 16 paired input channels through DA88 (DTRS) standard D-Sub connectors. For additional flexibility, the first two channel pairs can be switched to mono, handling, for example, Kick, Snare, Bass, and Lead Vocal as opposed to two stereo pairs. Mix inserts on balanced TRS jacks are available on each input for external processing units such as EQ or channel compressor/limiter. The mix inserts can be switched for pre- or post-position for integral Sumo dynamics processing or bypassed completely. Separate mix and monitor outputs are provided using balanced XLR connectors.

    Expandable to 64 Analog Inputs
    Sumo offers the option for input expansion for up to three additional Sumo units yielding a total of 64 analog inputs. Each Sumo unit delivers a 120dB dynamic range while providing an extremely low noise and low distortion environment.

    AES/EBU Digital Output Card

    The AES/EBU Digital output Card offers clock rates selectable from 44.1, 48, 88.2, 96, 176.4 and 192 kHz. The card output can be externally clocked via a rear-panel BNC connection.

    Audient Company History

    While British-based Audient is fairly new on the scene (1998), the company's founders have quite a respectable pedigree. Co-founder David Dearden has worked with David Manley (original owner of Manley Laboratories), Eddie Offord (Emerson, Lake and Palmer, Yes), and was involved in building a custom console and private studio for John Lennon for his Imagine sessions, followed by studios for George Harrison, Ringo Starr, Gus Dudgeon (producer, Elton John, David Bowie), and Chris Squire of Yes. After three years with MCI and two years with Soundcraft, David Dearden and Gareth Davies (also from Soundcraft) formed DDA (Dearden Davies Associates), a maker of high-quality analog consoles. When DDA became part of the Klark Teknik Group, he also designed the Midas XL200 live sound console and did the initial concept and design of the Midas H1000 console. In 1997 he rejoined with Gareth Davies to form Audient, whose products are typified by high performance, intelligent ergonomics, and transparent sound quality. Notable users of Audient gear include Pete Townshend's Eel Pie Recording, Abbey Road Studios, and England's Royal Academy of Music, to name a few.
