Operational Manual Overview – The Benefits of Analogue Summing OVERVIEW – THE BENEFITS OF ANALOGUE SUMMING Having bought the unit, you’ve probably figured out that Sumo is a high-resolution summing amplifier with stereo bus compressor and peak limiter, not to mention a handy little monitor section. Nevertheless, here are a few more interesting and descriptive words with which to impress your inquisitive friends.
Operational Manual Overview – The Benefits of Analogue Summing This means that Sumo can take whatever you throw at it without distortion or noise. Another feature of large format studio consoles is the inclusion of a compressor over the main stereo bus. Consequently, the bus compressor from the ASP8024 has also been included in Sumo’s design: a flexible, high quality compressor capable of polishing a mix to perfection.
Operational Manual Plugs and Sockets PLUGS AND SOCKETS Audio Interfaces The 16 inputs are connected via two Tascam DA88 connectors. type female Interconnect D-Sub cables are readily available in pre-wired form from Audient and from any good cable manufacturer. You can get these with different tail types to suit your other equipment, see the accessories section on page 18. Always use balanced connections to reduce any cable interference and noise.
Operational Manual Pin conventions AES/EBU on XLR, and S/PDIF on To unbalance the outputs of the Sumo the RCA (that’s a phono plug to you and I). -ve Pin should be connected to its Output on both connectors, for all sample adjacent 0v pin at Sumo’s output. rates is fixed at 24bit. Similarly, inputs from unbalanced sources A word clock input is also provided for should be connected via twin screened situations where Sumo is not the clock cables with the –ve pin connection tied to master.
Operational Manual Hooking Up HOOKING UP Before starting, it’s always a good idea to This stage is pretty important, make sure that your monitor speakers are because you’re converting back muted and/or turned off – this ensures into the digital domain and the that nothing gets popped or blown up quality of this conversion will when cables are being fiddled with and effect your overall mix, so make while power is turned on. sure to use the best converters you have available.

Operational Manual Knobs, Buttons and Flashy Lights KNOBS, BUTTONS AND FLASHY LIGHTS Input Section MONO Buttons – Under normal circumstances, all of the odd numbered channels entering Sumo are routed to the left side of the bus, while even numbers are routed to the right. Of course, this is going to sound a little unusual if your kick drum appears on the left and your snare is on the right, etc.
Operational Manual Knobs, Buttons and Flashy Lights MIX COMPRESSOR/PEAK LIMITER DYNAMICS ‘In’ Switch – Puts both compressor and limiter in circuit. When the dynamics are out, they are hard bypassed, clearing the signal path of any unnecessary components. Threshold – Sets the point at which compression begins to work. Due to the soft-knee characteristic of the compressor, some slight gain reduction is applied before the threshold level. This gives the compressor a gentler, more musical response.
Operational Manual Knobs, Buttons and Flashy Lights Adjusting this will vary the way the compressor handles transient sounds. Where control of unruly transients is required, a faster attack will clamp down on peaks. However, if larger amounts of gain reduction are applied, unnecessarily fast attack times may affect high frequency content. The Peak Limiter ’s response is fast attack, fast release, and very hard.
Operational Manual Knobs, Buttons and Flashy Lights Digital Section SAMPLE RATE – Rates of 44.1, 48, 88.2, 96, 176.4 and 192kHz are supported. The desired sample rate can be selected by pressing the select button repeatedly whereby the sample rate will cycle through internal rates and then the external Word Clock source. Lock – When the external clock source is selected, the select switch will flash until the converters are synchronised, or ‘locked’, with the external source.
