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-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. By placing one of these boxes close to the unbalanced output (before the cable run to the balanced input), the connection will benefit from the input device’s common mode rejection capabilities, reducing noise and interference.
