3.1: INTRODUCTION TO I/O
The Signature console offers a choice of industry standard audio inputs and outputs. All Jack and XLR 
inputs are balanced. Below are some terms used in this manual and on the console labelling that may 
be of use to you.
AUX (Auxiliary) Output
An output bus made up of the summed Aux 
contributions from input channels. In other 
words, the AUX1 output will be a mix of all input 
channel signals, with levels controlled by the 
AUX1 controls on the individual input channels. 
Auxiliary mixes are used for many purposes - 
alternative mixes for monitoring, processing by 
external FX units, and more.
Balanced
A ‘Balanced’ signal (Balanced Line) is one where 
the signal is split between two conductors with 
the same impedance / impedance to ground. 
At a differential input, the differences between 
thetwoconductorsareamplied,soanynoise
acquired between output and input is rejected 
(common-mode rejection).
GRP (Group)
An output bus made up of the summed 
contributions from any inputs routed to the 
Group. For example, on the Signature 12 and 
12MTK consoles (Groups not available on 
Signature 10), all inputs with their 1-2 buttons 
pressed will be added to the Group 1 and 2 
mixes. The pan / balance control determines how 
the signal is proportioned between the Group 1 
and Group 2 busses (Group 1 left, and Group 2 
right).
Hi-Z
High Impedance. Guitar pick-ups generally have 
‘high impedance’ outputs and therefore require 
asignicantlyhigherthanusualinputimped-
ance when plugging them directly into a console 
(straight from the guitar plug - not via an amp 
or a microphone). Hi-Z Inputs provide this. On 
the Signature console selected inputs have Hi-Z 
input switches to accommodate Hi-Z sources.
Jack
This is the long, quarter-inch connection most 
commonly used on the signature console for 
line level inputs and outputs such as keyboards, 
external FX processors, playback and recording 
devices, and so on. All Signature-series Jack 
sockets are ‘Tip-Ring-Sleeve’ 3-pole types. Jack 
outputs are impedance balanced.
Line
For inputs and outputs this refers to a line level 
signal. This is a higher voltage signal than ‘mic 
level’.
Mic
Microphone. For inputs and outputs this refers to 
a mic level input. This is a lower voltage signal 
than ‘line level’.
MST (Master)
Master Stereo Output: The main stereo Group 
output made up of the summed contributions 
from any inputs routed to ‘MST’ with their ‘MST’ 
buttons.
RCA
The small line-level connector commonly found 
on consumer playback equipment. RCA inputs 
are provided for the 9/10 (Signature 10) and 
11/12 (Signature 12 / 12MTK) stereo input 
channels (Playback Channels).
USB - Universal Serial Bus
Standard serial data connection used by the 
Signature console for sending and receiving 
digital audio streams.
XLR
The round, three-pin connections. On the 
Signature console they are used for microphone 
inputs and the main stereo outputs.
