Portico 5045 Primary Source Enhancer

Yamaha Rupert Neve Portico 5045 Primary Source EnhancerIf you had a chance to attend one of our recent Yamaha CL Series events, you may have had the chance to hear the Portico 5045 Primary Source Enhancer from Rupert Neve Designs.

The 5045 Primary Source Enhancer is a single rack space, two channel device that is exceptionally useful at reducing feedback, effectively increasing microphone gain before feedback by up to 20dB, without negatively impacting the sonic integrity of the source signal.

With controls that are very simply laid out that require minimal adjustment, the 5045 is an invaluable tool for churches, stadiums, performance halls, or any venue where feedback can be a problem.

The 5045 shares some traits with conventional “noise gates”, but operates with a different principle.  They both reduce the gain during the absence of signal—or more specifically, both begin to attenuate when the level of a signal falls below a certain user-defined threshold. The 5045 senses when someone is speaking or singing into the mic and allows the signal to pass through, and senses when the person has stopped talking or singing and reduces the gain appropriately, which helps reduce the tendency of a system to feed back.

Most importantly, the 5045 does not require filtering and digital processing to achieve significant benefits—it is a completely analog processor.

We’ve had great success using the 5045 on the referee mic at Big Ten football games, and have clients using them with speakers on lavaliers or podium mics.

We have the 5045 in our rental stock if you’d like to check one out—this really is a piece you need to hear to understand.
