Detailed Description

SuperAnalogue Mono Channels

There are two SuperAnalogue mono channels on SiX; each channel has identical facilities.

This section explains the features found in each.

SuperAnalogue Pre-Amp input

SiX’s pre-amp is a new wide gain range SuperAnalogue design, developed from the mic

pre-amps of the larger SSL Duality and AWS consoles. In these consoles, line and mic

inputs are served by separate pre-amps. In SiX, a new wide gain range, ultra low noise

SuperAnalogue design provides both Line and Mic facilities with a “Line” gain range switch

to cover a wide range of source levels.

The pre-amp consists of a microphone input (XLR) and line level input (¼” TRS Jack Socket).

Mic Input (XLR)

The default microphone input uses SSL’s SuperAnalogue design and includes individually

switched 48V phantom power. The Mic (XLR) input’s nominal impedance is 1.2 kΩ.

The XLR is the default source input, the source can be switched to the ¼” TRS jack line input by pressing the ‘Line’ switch on the

channel. The nominal Line Input impedance is 10 kΩ this can be changed to 1 MΩ using the Hi-Z switch. This input impedance

makes this input suitable for very high impedance sources such as passive guitar pickups without the need for an external DI box.

The Gain control adjusts either the microphone pre-amp gain (+6 dB to +72 dB), or the Line amp gain (-3 dB to +63 dB), depending

on the selected input source. Following the pre-amplier is a switched 12 dB/oct, 75 Hz High Pass Filter (HPF) to reduce unwanted

LF such as Microphone Rumble, AC noise etc.
