Sonifex Show New Passive Packs at NAB 2018
6th February 2018
On stand C3035 at NAB 2018, Sonifex are showing a new range of products called ‘Passive Packs’. The Passive Packs consist of six small utility products which use transformers to change audio input, output impedances and levels to distribute audio signals. Thus, they have no power supply and act passively. There are two types of product: Headphone Amplifiers and Matching Amplifiers.
The two Headphone Amplifies are the CM-HPR1 Headphone Volume Control and the CM-HPX1 Headphone Volume Control. Both allow the connection of a stereo balanced line to create a headphone output. The CM-HPR1 uses a RJ45 with StudioHub+™ pinout and is transformer balanced, whereas the CM-HPX1 uses two female XLRs.
There are four Matching Amplifiers. The CM-LUR1 and CM-LUX1 are Balanced to Unbalanced Audio Converters. Both convert a stereo balanced line input to a stereo unbalanced line output on phono connectors, with the CM-LUR1 using an RJ45 with StudioHub+™ pinout and the CM-LUX1 using two female XLRs.
The CM-ULR1 and CM-ULX1 are Unbalanced to Balanced Audio. Both units convert a stereo unbalanced line input on phono connectors to a balanced line output, but the CM-ULR1 does this using an RJ45 with StudioHub+™ pinout and the CM-ULX1 does so with two male XLRs.
