Page 11 Introduction BB100 Hardware The BB100 Series is a range of compact, high quality audio consoles designed for broadcast professionals. Although it has been designed primarily for broadcast use, the BB100 will find numerous applications in other areas where a cost-effective and flexible audio mixer is required that does not compromise build quality or performance in the least.
Page 14: Installation
All power units should be placed close enough to the console to use the standard 8 metre DC power cables. Avoid placing the units close to other sensitive audio equipment to reduce the risk of hum pickup from external stray magnetic fields e.g. mains transformers. © AMEK Issue 3 Installation...
Page 15 Only when the console is carefully installed in accordance with our recommendations, will you obtain the best results. EMC precautions are described at the end of this chapter. Installation Issue 3 © AMEK...
Page 16 Wiring Conventions Amek uses the standard XLR wiring convention on all consoles. Not all equipment uses this convention so check your wiring to prevent any phase reversals. See Table below for wiring convention.
Page 17 All maintenance and repair work should be carried out by a qualified and trained technician. Failure to do so may invalidate the product warranty. Refer to the warranty information in Section 1 of this manual. Installation Issue 3 © AMEK...

Page 19 (31,6 to 1000 MHz). Care must therefore be taken with the location of the antennas and receivers. Installation cables - type and location Amek consoles are designed to have good EMC performance, but a poor installation can easily negate this. Type of cable For best EMC performance, audio circuits should all be wired in twisted-pair screened cable.
Page 20 Modifications to the console can easily reduce the effectiveness of the console’s EMC. If any changes are made, the person who made them becomes the “owner” of, and therefore responsible for, the console’s EMC performance. © AMEK Issue 3 Installation...

Never remove any green/yellow earth connections. If you have earth loops in your installation, they must never be ‘solved’ by removing safety earth connections. The IEC connector is supplied, moulded to the mains lead and should not be rewired. © AMEK Issue 3 Power Supplies & Cabling...
Page 25: Supply Types & Description
There are no user serviceable parts in the units. In the event of failure for any reason, the switched mode module should be replaced with a spare and the faulty module returned to AMEK for repair or replacement subject to current warranty conditions. All switched mode modules must be fitted by qualified and approved technicians.
Page 26: Installation
Use a small screwdriver to prise the fuse carrier from its location in the connector. Check the fuse and replace if necessary. In the event of repeated failure of the mains fuse consult the AMEK dealer from where the unit was purchased.

Console Types All specifications for the BB100 console apply to consoles that are installed completely in accordance with Amek’s recommendations. This includes recommendations on power supply cables and grounding. The figures in this specification are typical figures measured on a console, immediately after completing normal production tests.

Page 80 5. These figures are typical of performance in a normal electromagnetic environment. Performance may be degraded in severe conditions. 6. Amek has an established policy of seeking improvements to designs, specifications and manufacture of its products. Alterations take place continually, often without notice outside the company. Amek’s literature must not be taken as an infallible guide to the specifications available despite a considerable effort to produce up to date information.
