Approved Lighting Technicians
must provide a competent Sound Operator for the duration of their production who
must be approved by a Director/Trustee. For productions where the sound system
is not being used for the performance, the operator must at the very least be
able to operate the pre-show, interval and after show announcements and assist
in clearing the car park at the end of the performance as detailed below.
sound installation in the theatre is based around the sound mixer and a number
of amplifiers and is run from the sound box at the front right hand side (facing
the stage) of the gallery. The system has been designed to cater for differing
requirements of users of the theatre, providing basic background music and public
address announcements, show music/effects (fx) and full show reinforcement.
Theatre has a loop amplifier system which is entirely self-contained, picking
up via microphones over the proscenium, and available for use by patrons with
hearing aids, this system must be switched on for ALL public performances, regardless
of whether there is any other use of the sound installation.
Sound Operators Duties.
Sound Operator is responsible for the operation of the entire theatre sound system,
including the main P.A./reinforcement and effects installation, the Canford Tecpro
net communication system and the backstage relay system (locally under the control
of the Stage Manager).
addition to this the Sound Operator is required to run the pre show, interval
and ending announcements (on CD, see below for more
detail) to help front of house get the audience seated by curtain up and to ease
congestion in the car park after the show finishes. This is an important duty
to ensure smooth running of the performance and to enhance our patrons' experience
of the theatre. It is not optional.
system is controlled by the 24-channel mixer and can be broken down into separate
sub systems, as described below -
Public Address / Background Music.
background music system is based around a Talisman 1001 amplifier serving 100
Volt line loudspeakers placed in the auditorium and foyer areas. The bar speaker
system is served by its own amplifier situated in the control room adjacent to
the stage, fed via an aux send from the main sound desk. Switches allow the auditorium
and foyer to be addressed independently or together. There is a microphone in
the sound box, routed through the mixer (see below) into the Talisman and bar
amp. Background music can also be routed through this mixer into the P.A. system.
The background system is not designed to provide high levels of sound and should
not be used to provide stage FX or music.
Show FX / Music.
system consists of a double CD player, and a Mini Disc player / recorder. These
are routed through the mixer and feed three pairs of loudspeakers in the auditorium,
plus a fourth pair mounted at high level at the rear of the stage.
Mixer controls the various sources via faders, which are labelled accordingly.
regarding P.R.S. returns are given in the hirer's pack given out by the Theatre
is also a set of SFX CD's available on request and which should be returned after
use. On no account are these CD's to be taken out of the theatre.
system is primarily for use in musical presentations to enable the voices of performers
to be heard over the orchestra. There are 5 shotgun and 3 boundary effect microphones
available which can be placed across the front of the stage on stands.
are patched into the stage boxes, on the proscenium columns either side of the
stage. These microphones should only be placed once all construction etc. on the
stage is completed to avoid dust and mechanical damage. There are also three Shure
SM58 vocal microphones which can be hand held or used on stands as required.
there are 8 radio microphones (tie clip type) which can be hired for use plus
one hand held mic. freely available in the theatre, by arrangement with the Barn
Theatre Management. Mics. are assigned as follows: - Ch. 1-5, float Mics. Ch.
6-14 radio Mics. The usual configuration is noted on the strip at the foot of
the mixer. Radio Mics come into the mixer via their receivers which have to be
switched on (also do not forget to turn on the individual transmitter packs! These
require batteries which are the responsibility of the hirer). The mixer is equipped
with eq., aux. sends and pan control, etc. two reverb units are available and
can be patched into the signal route as required.
Mic Frequencies (MHz) as of 02/07/2010
frequencies must not be changed.
outputs are available for recording direct from the desk (check copyright of material
/ performance before recording!).
To use the equipment, first check that the "Auditorium Ring" circuit breaker in
the Stage Manager's box is on, then switch on the master switch and socket outlets
sited on the rear wall of the sound box. The various pieces of equipment will
then come on. They are normally not switched off independently but if any individual
piece of equipment does not work, check that it is on first.
amplifiers are situated in the lighting Control Room at the rear of the balcony
and must be turned on AFTER the main desk and turned off BEFORE the desk is powered
down, to avoid damage to the speaker installation. The four amplifiers are labelled
front, mid & rear auditorium plus the Bass Bin driver which can be left switched
off if not required (i.e. for situations where only vocal reinforcement is required).
discs etc. and test the system before the audience arrive, problems can usually
be sorted out before curtain up, and it is very much more difficult to rectify
the show liaise with the Front of House Manager over the house
calls. Theatre time is taken to be the radio controlled clock at the stage managerís
position, please make sure you are synchronised with this. Every effort should
be made to ensure that the show goes up promptly; it is essential that you liaise
with FOH & with your Stage Manager on this point
are CDs provided to make the pre show and interval announcements. The pre show
announcements run for 15 minutes ending at curtain up. The interval announcements
run for 20 minutes. The FOH manager has control of an interval bell, make sure
that your calls coincide with this, or that the bell is rung on your calls. There
is a track on the CD to run at the end of the show, marked "Car Park" which asks
drivers to check they are not blocking in people behind them in the car park.
(Not all patrons leave immediately and those waiting for cast members often forget
they may be causing congestion in the car park).
After the show, to avoid congestion in the car park, liaise with front of house
and be prepared to announce registration numbers as required, ideally using the
hand held radio mic. from the car park. This must take precedence over clearing
up and/or retrieving mic. packs from performers at the end of the show. After
your production return all microphones to their cases with batteries and tape
etc removed, leads and stands to the control room, CD's to their cases provided.
Please leave the sound box and control room tidy and ready for the next use.
In the event of a fire or other emergency requiring evacuation
of the theatre the Sound Operator will be required to make an announcement over
the P.A. to inform the entire theatre (front of house & backstage) how and where
to evacuate to. There is a special red CD marked up "Emergency Evac. Announcement"
which will continue to repeat the announcement at 2 minute intervals for approximately
30 mins. This should be used whenever directed by the Stage Manager/Front of House
with Front of House staff and the Stage Manager will assist in the evacuation,
The Sound Operator should also ensure that the balcony is empty before making
his/her way to the assembly point.
an overall sound level limit set by Tandridge District Council within the auditorium,
to be measured at the centre of the hall, of 110 Decibels ("A" scale). This level
must not be exceeded AT ANY TIME during rehearsals or public performances. The
continuance of the theatre's licence depends on this and it is the responsibility
of the Sound Operator to ensure that this level is not exceeded. A sound level
meter is available for checking sound levels, by arrangement with the Sound Director
or any member of the Theatre Management. The Management reserves the right to
demand that the levels be turned down at any time and if levels are exceeded despite
warning, to pull the plug! YOU HAVE BEEN WARNED.
