Press Release
New Sonifex Passive Packs in Stock Now
22nd August 2017
In a world first experience for us, we've managed to produce a range of products and put them in stock before we've even told you about them or given you pricing .... don't expect this kind of efficiency to last though!
The new Passive Packs are a range of small utility products which use transformers to change audio input & output impedances and levels and to distribute audio signals. There are a few products to suit different needs: headphone volume controls, balanced to unbalanced audio converters and unbalanced to balanced audio converters.
We've also included our existing CM-AESB3, CM-AESX3 and CM-MS3 audio distribution units into this range as well, to give a common sized footprint for the passive packs meaning that all of the products, along with the CM-TBU and CM-TLL, can be mounted to the underside of a desk using the CM-MNT1 desk mount plate.
For more information please speak to our sales staff on +44 (0)1933 650 700, sales@sonifex.co.uk or visit the product web pages.

CM-HPR1 & CM-HPX1 Headphone Volume Controls
These two products allow the connection of a stereo balanced line input (RJ45 on the CM-HPR1 with StudioHub+™ pinout and 2 x female XLRs on the CM-HPX1) and create a headphone output, with level control.
They are transformer balanced, and can be used with any headphones above 150Ω impedance.
The transformer ratio of 2:1 ensures that any headphone load presented at the output is reflected through to the input at a 1:4 ratio (hence a 150Ω set of headphones looks like 600Ω at the input, a suitable load for most good quality line output stages).

CM-LUR1 & CM-LUX1 Balanced to Unbalanced Audio Converters
These two products allow the connection of a stereo balanced line input (RJ45 on the CM-LUR1 with StudioHub+™ pinout, 2 x female XLRs on the CM-LUX1) to a stereo unbalanced output on stereo phono connectors.
They are transformer balanced, with a 2:1 ratio, so 6dB of attenuation is added to the input to help interface with the lower signal levels associated with consumer outputs.

CM-ULR1 & CM-ULX1 Unbalanced to Balanced Audio Converters
These two products allow the connection of a stereo unbalanced line input on phono connectors to a balanced line output (RJ45 on the CM-ULR1 with StudioHub+™ pinout, 2 x male XLRs on the CM-ULX1).
They are transformer balanced, with a 1:2 ratio, so 6dB of gain is added to the input to help interface with the higher signal levels associated with professional outputs.
These units are passive versions of the RB-UL1, and provide you with an alternative to wiring an unbalanced output directly into a balanced input.

CM-MNT1 Desk Mount Panel
All of the Passive Packs, along with the CM-TBU and CM-TLL, can be mounted to the underside of a desk using the CM-MNT1 desk mount plate. This fixes to the top side of the product and screws to the underside of a surface.
