CAUTIONS
l To avoid the risk of fire, replace the mains fuse only with the correct type and
value fuse, as marked on the rear panel.
l AVIS: - Afin de réduire le risque de feu remplacer seulement avec fusible de
même type.
l REPLACING MAINS FUSE
Switch the ON/OFF switch to the OFF position. Remove the mains lead from the connector. Use a small screwdriver to prise the fuse carrier from its location in the connector.
Check the fuse and replace if necessary; also check that the voltage selection is correct for
the mains supply level before switching the unit ON again.
If the mains fuse fails repeatedly this may be because an electrical safety hazard exists. The
unit must be taken out of service and referred to the Soundcraft/Spirit dealer from where
the equipment was purchased.
l THIS UNIT MUST BE EARTHED
Under no circumstances should the mains earth be disconnected from the mains
lead.
l AVIS: - Cet appareil doit être branché à la terre.
l The wires in the mains lead are coloured in accordance with the following code:
Earth: Green and Yellow (Green/Yellow - US)
Neutral: Blue (White - US)
Live: Brown (Black - US)
As the colours of the wires in the mains lead may not correspond with the coloured
markings identifying the terminals in your plug, proceed as follows:
The wire which is coloured Green and Yellow must be connected to the terminal
in the plug which is marked with the letter E or by the earth symbol.
The wire which is coloured Blue must be connected to the terminal in the plug
which is marked with the letter N.
The wire which is coloured Brown must be connected to the terminal in the plug
which is marked with the letter L.
Ensure that these colour codings are followed carefully in the event of the plug being
changed.

v Mic/Line Interface Contents
l This unit is capable of operating over a range of mains voltages as marked on the rear panel.
It is important to ensure that the correct mains fuse is fitted before switching on the unit.
WARNINGS
l Read these instructions.
l Keep these instructions.
l Heed all warnings.
l Follow all instructions.
l This unit contains no user serviceable parts. Refer all servicing to a qualified ser-
vice engineer, through the appropriate Soundcraft dealer.
l Do not use this apparatus near water.
l Clean only with a damp cloth.
l Do not block any of the ventilation openings. Install in accordance with the manu-
facturers instructions.
l Do not install near any heat sources such as radiators, heat resistors, stoves, or
other apparatus (including amplifiers) that produce heat.
l Do not defeat the safety purpose of the polarized or grounding-type plug. A polar-
ized plug has two blades with one wider than the other. A grounding type plug has
two blades and a third grounding prong. The wide blade or the third prong are
provided for your safety. when the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet.
l Protect the power cord from being walked on or pinched particularly at plugs,
convenience receptacles and the point where they exit from the apparatus.
l Only use attachments/accessories specified by the manufacturer.
l Unplug this apparatus during lightning storms or when unused for long periods of
time.
l Refer all servicing to qualified service personnel. Servicing is required when the
apparatus has been damaged in any way such as power-supply cord or plug is
damaged., liquid has been spilled or objects have fallen into the apparatus, the
apparatus has been exposed to rain or moisture, does not operate normally or has
been dropped.
l It is recommended that all maintenance and service on the product should be
carried out by Soundcraft or its authorised agents. Soundcraft cannot accept any
liability whatsoever for any loss or damage caused by service, maintenance or
repair by unauthorised personnel.
l Use only with a cart, stand, hood, bracket or table specified by the manufacturer
or sold with the apparatus. When a cart is used, use caution when moving the cart
apparatus combination to avoid injury from tip-over.

Mic/Line Interface Introduction 1.1
IInnttrroodduuccttiioonn
Congratulations on your purchase of the Mic/Line Interface from Spirit by
Soundcraft. You are about to enjoy one of the great features of the Digital product line from Spirit - Expandability.
The team would like to you to know that we take great pride in our products and
may we wish you many successful years with your new purchase.
Please be aware that the recommended TDIF Cables are not supplied with the
unit, but are available from your Spirit dealer.
The Mic/Line Interface is designed to meet the following requirements:
As an 8 channel bi-directional analogue audio interface to a Spirit Digital 328/324
Mixing Console.
As an 8 channel bi-directional analogue audio interface for any other Digital Mixing
Console fitted with a TDIF-1 Input / Output connection.
As an 8 channel bi-directional analogue audio interface for any Digital Multitrack
Tape Recorder fitted with a TDIF-1 Input / Output connection.
As an 8 channel bi-directional Digital audio interface for any Analogue Multitrack
Tape Recorder or other device fitted with analogue Input / Output connections.
This interface is primarily an external accessory for the Digital 328/324 and other
forthcoming Spirit Digital consoles. This interface provides eight channels, each
with a Microphone Input, Line Input, Insert Point and a Direct Output. All channels include a Trim Control, High Pass Filter, Channel Metering, Insert Point
switching and individual Phantom Power switching.
OOppeerraattiioonn
1) Connect the TDIF cable from the Interface to the required TDIF port on
the Digital 328/324 as shown below.
Rearcon of 328
Rearcon of Mic/Line Interface
2) To configure the Digital 328/324 as the wordclock master, enter the
328/324 menu pages by pressing the <MENU> button on the right hand
side of the LCD display. Using the encoder beneath the display, scroll up
or down until the 'Clock Source Sel' menu is highlighted, and press
<ENTER>. Here, either the internal 44.1kHz clock or the internal 48kHz
clock must be selected, depending on the sampling rate at which work is to
be done. Press <ENTER> to set the sample rate and <MENU> to
return to the menu pages.
1.2 Mic/Line Interface Introduction
3) To ensure that the Digital 328/324 Tape Ports are set to TDIF to work with
the Mic/Line Interface, enter the 328/324 Menu pages by pressing the
<MENU> button on the right hand side of the LCD display. Using the
encoder beneath the display, scroll up or down until the 'Tape Port Select'
menu is highlighted. Press <ENTER> and keep pressing the Up cursor arrow
until the '<Tape Ch17-24 >' menu page is displayed. Using the encoder set
the Bank Source to TDIF. Press the Down cursor arrow once, to set the
wordlength. The Mic/Line Interface is capable of 24-bit operation, and so for
optimum results, 24-bit wordlength can be selected here. If your work is
being carried out at a wordlength other than 24-bits, 20-bit or 16-bit should be
selected. Please note that when the ouputs are 20/16-bit then the dither is
automatically applied by the console.. The wordlength is set on the 328/324
with the encoder. Press <ENTER> to set the wordlength and <MENU> to
return to the menu pages.
4) You will now be able to bring in the audio inputs to the interface on Tape
Returns 17-24 (Port A), or 25-32 (PortB).
5) The outputs from the interface can be fed directly from two possible sources:
a) The direct outputs from Channels 1-16, sequentially to tape sends 17-32.
b) The group outputs 1-8 on selected.ports.
The selection is simple - if on the Mic/Line channel T.SND DIR is engaged then
the port will be fed with the direct outputs from channels 1-16 sequentially.
Therefore channels 1 would be send to tape send 17, 2 to 18 etc.
When T.SND DIR is not selected on any of the Mic/Line channels, the ports
will be fed with Groups 1-8 sequentially.
