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.

Fig A: CM-MNT1 Desk-Mount Plate Fitted On CM-ULX1

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.
