Page 13: Introduction
Innovative Design • The S2 chassis is available in 5 channel width sections, allowing 5, 10, 15, 20, 25 and 30 channel width mixers. This means S2 can be used for small newsrooms or large on-air situations. The following table shows the model number along with the total channel width.
Page 14: Fig 1-2 : S2-7Ss Script Space
I N T R O D U C T I O N • The Script Space (S2-7SS) occupies an area of 7 channel widths, and is designed to hold documents / scripts for the Mixer operator when desk space is at a premium.

Page 16: Installation Notes
2 Installation Notes Atmosphere The S2 mixer should be installed in an area which is not subject to excessive heat or cold. Also, you should avoid installing it in atmospheric conditions which are dusty, smoky, or dirty, or where there is moisture or vibration.

Page 28: Power Supply
Front Panel The S2-PSU is a 2U high rack-mount unit, which can supply power to the entire range of S2 mixers. A lead with a special 9 pin D-Type socket (see Fig 2-9) on each end is used to connect the power supply to the mixer.
Page 29: Rear Panel
The rear panel of the equipment carries the Serial Number of the machine. The operating voltage of the S2 power supply is selectable at the fuse carrier on the power inlet port of the S2-PSU unit. Ensure that the machine operating voltage is correct for your mains power supply.
Page 30: Ordering The Correct Mains Lead
If no moulded plug has been supplied with your S2, please contact your supplier, because an IEC connector is always supplied from the Sonifex factory. If for any reason, you need to use the S2 with a diﬀerent power cable, you should use the following wiring guidelines.
Page 31: Fuse Rating
P O W E R S U P P LY Fuse Rating The S2 is supplied with a single fuse in the live conducting path of the power infeed at the power supply. For reasons of safety it is important that the correct rating and type of fuse is used.
Page 32: S2-Psus Dual Power Supply Switcher
P O W E R S U P P LY S2-PSUS Dual Power Supply Switcher The S2-PSUS is a passive power switcher which takes the power feeds from 2 x S2-PSU units and switches between them in the event of failure. Two trailing leads 0.5m in length connect to 2 x S2-PSU units.
