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
thetwoconductorsareamplied,soanynoise
aquired 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
asignicantlyhigherthanusualinputimped-
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 accomodate 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.
