Electronic Line Output Devices
• Keyboards, Drum Machines, CD Players, DAT
Machines, Wireless Mic Receivers, all provide line level
outputs, and should all be connected straight into the
Mixer’s Line Inputs. If some of your instruments are
STEREO connect their left and right outputs to a spare
stereo input. Alternatively connect to an adjacent pair of
mono inputs and Pan the inputs hard left and right to
create a stereo image.
B. Equipment Requiring Both
Inputs and Outputs
External effects units
Connect the input of your effects unit marked "mono" to
A POST FADER AUXILIARY OUTPUT. If you are
uncertain, Post fader auxiliaries are coloured blue on
Soundcraft mixers with the relevant channel aux pots
usually marked "post". The left and right outputs from the
effects unit should be connected to a pair of stereo returns,
or stereo inputs if stereo returns are not available. If
intensive EQ is required, use a pair of Mono Inputs.
Remember, the effects signal is no different from any other
audio signal – it still requires an input to the mixer.
See Section 3 Mixing Techniques or a detailed explanation of post
fader auxiliaries.
NB: YOU DO NOT HAVE TO CONNECT UP BOTH THE
LEFT AND RIGHT INPUTS OF YOUR EFFECTS UNIT
TO SEPARATE AUXs. Most units only require "pseudo-stereo"
operation and will mimic a stereo reverb or effect inside before
providing a stereo output to the mixer’s returns.
Signal Processors
Connect signal processors, such as compressors to the insert
jack using a special insert ‘Y’ cable. This allows the signal to
be sent and returned to the mixer using only one
connector.
Refer to section 7 for wiring information.
It is also possible to connect the processor to the console
without using the insert jacks by connecting an instrument
direct to the processor first. However, the advantage of
using processors in the mix/group or channel inserts is that
any level changes made by the processor can be monitored
by the mixers meters.
NB: A signal processor can be used in a channel to control one audio
source, across a group to control a number of audio sources or
across the entire mix.
Tape machines
Multitrack machines are used for initial track-laying in
either studio or live recording situations.
For more sophisticated work, a stand-alone machine offers
better sound quality and greater versatility than a cassette
multitracker. The new generation of digital multitracks are
also very attractive, but analogue, open-reel multitracks are
also capable of professional sounding results. Aim for a
minimum of eight tracks if your budget will allow.
Mastering Machines
Your final mix should be recorded on the best quality
machine that you can afford. A recording is only as good as
the weakest link in the chain, and a good cassette machine
is fine for demos, but for more serious work, consider a
DAT machine or perhaps a second hand, open-reel 2-track.
C. Output Devices
Amps and Speakers (Monitor and FOH)
Studio Monitoring
A high-powered hi-fi amp of around 50 watts per channel
is fine for home recording, but to ensure adequate head-
room you should consider a well-specified rack mount amp.
Similarly, a pair of accurate hi-fi speakers will do the job,
but for more serious work we would recommend purpose-
designed nearfield monitors. Always remember that no
matter how good the recording or performance, a poor
monitoring set-up will not allow you to make qualitative
judgements about the mix.
Headphones
When choosing headphones for monitoring, you’ll
obviously want a pair that give the best sound reproduction
for the price. But, bear in mind that in order for you to
fully concentrate on the mix, the headphones should
exclude outside noise - therefore open-back designs
will be of little use.
Furthermore, you could be wearing the headphones
for several hours at a stretch so comfort is essential.
NB: Make Sure that the IMPEDANCE of your headphones matches
the specification of your mixer.
PA Work
PA work requires high-powered, rugged, and honestly
specified amps and FOH (Front of House) speakers. The
power rating of the system will depend on the size of
venues you will be playing.
See PA Mixing, Section 4, for more information.
