Max Headroom: For U.S. Broadcasters, It’s More Than Vintage TV


German converter manufacturer Ferrofish has added the new +24dBu I/O model to its Pulse16 Series of AD/DA converters. The new modification increases the maximum input and output level from +20dBu to +24dBu, an important upgrade for American broadcasters requiring proper headroom.

“One of the core components at Ferrofish is providing end-users with cost-effective, high-performing converting solutions,” said Derek Badala, Director of Sales for the Americas for Synthax, the regiona distributor of Ferrofish products. “This new modification is no different, offering US broadcasters with the tool they need to help them get the best possible audio experience.”

With the new Pulse16 +24dBu I/O modification, maximum input and output levels are increased from +20dBu to +24dBu (in steps of 1 dB), complying with the American SMPTE guidelines which call for +24dBu levels for the analog portion to keep all analog and digital levels uniform.

The Pulse16 is a high-density converter providing 16 x 16 balanced analog TRS I/O. Thanks to its Cirrus Logic converter chips, the Pulse16 operates with an active digital jitter elimination, which compensates shifts or jitters in the audio signal and provides audio engineers with the highest-quality audio possible. The Pulse16 family now includes the Pulse16 DX, Pulse16 MX and the original Pulse16. The new +24dBu I/O model is available for all Pulse16 versions.

In addition to the new Pulse16 +24dBu I/O model, Ferrofish also recently announced a new Pulse16 CV Out, perfect for users working with modular synths using CV/Gate technology.

In American broadcasting SMPTE guidelines call for +24dBu (decibel) levels for the analog portions of audio in order to keep all analog and digital levels uniform. This new Ferrofish Pulse16 model’s input and output levels are increased from +20dBu level (what the old version was) to the new +24dBu level to comply with SMPTE’s guidelines.
