declarations
WEEE Directive
The Waste Electrical and Electronic Equipment (WEEE) Directive was agreed on 13 February 2003, along with the related Directive 2002/95/EC on Restrictions of the use of certain Hazardous Substances in electrical and electronic equipment (RoHS). The Waste Electrical and Electronic Equipment Directive (WEEE) aims to minimise the impacts of electrical and electronic equipment on the environment during their life times and when they become waste. All products manufactured by Sonifex Ltd have the WEEE directive label placed on the case. Sonifex Ltd will be happy to give you information about local organisations that can reprocess the product when it reaches its “end of use”, or alternatively all products that have reached “end of use” can be returned to Sonifex and will be reprocessed correctly free of charge.
Atmosphere/Environment
This apparatus should be installed in an area that is not subject to excessive
temperature variation (<0°C, >50°C), moisture, dust or vibration.
This apparatus shall not be exposed to dripping or splashing, and no objects
filled with water, such as vases shall be placed on the apparatus.
Passive Packs
The 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 range of different products to suit different needs:
CM-HPR1 Headphone Volume Control
CM-HPX1 Headphone Volume Control
CM-ULR1 Unbal to Bal Audio Converter
CM-ULX1 Unbal to Bal Audio Converter
CM-LUR1 Bal to Unbal Audio Converter
CM-LUX1 Bal to Unbal Audio Converter
CM-AESX3 3 Way Dig AES3 Splitter, XLR
CM-AESB3 3 Way Dig AES3ID Splitter, BNC
CM-MS3 3 Way Microphone Splitter
CM-MNT1 Desk Mount Panel
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. This fixes to the top side of the product and screws to the underside of a surface.

CM-HPR1 & CM-HPX1 Headphone Volume Controls
Fig 1-1: CM-HPR1 Front & Rear View
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 1500Ω
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 1500 set of
headphones looks like 6000 at the input, a suitable load for most good quality
line output stages).
