8 Pump Station 16-R: I NSTALLATION AND OPERATION MANUAL
12 Global Input - High Pass Filter
The global input channel features a 3 pole high pass filter operating at 200Hz that can be
switched into the signal path to improve the intelligibility of speech; it also provides effective
attenuation of breath blasts and low frequency handling noises. If the global input is used for
music signals the filter should be switched to the ‘out’ position.
13 Global Input Priority
This feature provides the user with a fully automatic signal sensing input that has priority over
all channels. When a global input signal is detected, the music signals fed to every remote
control unit connected to the system will attenuate by approximately 30dB; once the global
signal ceases, the music signals will restore smoothly to their former level.
14 Balanced Line Output – Channel 16 only
Channel 16 on the Pump Station 16-R is fitted with a balanced line level output using a 3 pin
plug-in screw terminal type connector.

This output satisfies the occasional requirement to provide a signal to a separate sound system
such as a general background music system providing sound within a sports hall or gym. We
suggest that the channel 16 remote control unit be wall mounted in a convenient location. We
do not advocate that any headphones are connected to the remote control unit but the volume
control and source selector can be used to control the signal fed into the separate system.
The nominal output level is 0dBu (775mV). For balanced interconnections, 2 core screened
cable should be used. Connect the screen to left terminal (0V), the centre pin (+) is the in-phase
signal (normally red) and the right terminal (-) is the reverse phase signal (normally blue or
black). If you wish to connect this balanced output to an unbalanced input, connect the cable
screen to (0V) with the hot connection (inner core) connected to the centre pin (+). Make no
connection to pin on the right (-).
15 Remote Music Mute – Fire Alarm Interface
In certain circumstances, there may be a Local
Authority or Fire Service requirement to mute the
music signals via a fire alarm control panel in an
alarm condition. The Cloud Pump Station 16-R
provides a facility to mute the music signals of the
whole system by connecting pins 3 & 4 of the four
pole connector to the contacts of a relay which is
controlled by the fire alarm control panel. The two-
wire connection should not be connected to any
other circuit or voltage. In most instances, the fire
alarm installation company will provide an auxiliary
relay, normally located close to the sound equipment
rack. The global input will operate normally when
the music mute is operating. (See section 10)
