Portico 543: 500 Series Compressor-Limiter
Thank you for your purchase of the 543: 500 Series Compressor-Limiter. Everyone at Rupert Neve De-
signs hope you enjoy using this tool as much as we have enjoyed designing and building it. Please take
note of the following list of safety concerns and power requirements before the use of this or any Portico
Series product.
Safety
It’s usual to provide a list of “do’s and don’ts” under this heading but mostly these amount to common
sense issues. However here are some reminders:
Don’t operate your Portico™ module in or around water! Electronic equipment and liquids are not good
friends. If any liquid is spilled such as soda, coffee, alcoholic or other drink, the sugars and acids will
have a very detrimental effect. Sugar crystals act like little rectifiers and can produce noise (crackles,
etc.). SWITCH OFF IMMEDIATELY because once current starts to flow, the mixture hardens, can get very
hot (burnt toffee!) and cause permanent and costly damage. Please contact support as soon as possible
at [email protected] for resolution.
Don’t be tempted to operate a Portico module with the cover removed. The cover provides magnetic
screening from hum and R.F. stray fields.
Power Requirements
Each Portico 543 is fitted for use with standard 500 Series Rack Mounts and requires 110-125 mAmps
@+/- 16V
