Sonifex CM-HP Headphone Volume Control
Details
Sonifex is a manufacturer of broadcast audio equipment for the radio, TV, security and telecommunications industries. This is a family business, started in 1969 and has established a recognised position in the radio broadcasting industry.
The constant need to innovate is an integral part of the Sonifex culture, combining healthy and outward looking ideas with sound and efficient design practices and designs of equipment reflecting the quality and reliability that is expected by its customers.
Sonifex's CM-HP Headphone Volume Control provides the connection of a stereo balanced line input and creates a headphone output with level control. It is 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.
Two versions are available
SFX-CM-HPX1 - 2 x XLR female to 6.3mm Stereo Jack
The stereo analogue input is on two female 3 pin, offering XLR connectors with the following pin assignments of Pin 1: 0V Common; Pin 2: Phase and Pin 3: Non Phase
SFX-CM-HPR1 - Provides for Analogue cost effective connection using Category cable
The stereo analogue input is on a female RJ45 connector with the following standard StudioHub+™pin assignments of Pin NoConnection, 1Left Phase, 2Left Non-Phase, 3Right Phase, 4Ground, 5N/C, 6Right Non-Phase, 7N/C and 8N/C.
