Any studio that processes phone calls 
needs hardware to interface with phone lines. This device, traditionally
 called a Hybrid, filters, separates and provides gain adjustment and 
call control to more easily allow for recording or broadcasting 
“phoners”.
As telephone companies are shifting from traditional 
phone lines to Voice-over-IP (VoIP) systems, the devices that performed 
this job in the past are becoming outmoded. Broadcasters need a VoIP 
hybrid to ensure on-air and recorded phone calls sound as good as 
possible.
A dual-line hybrid, VH2 connects two VoIP lines to a 
studio for individual broadcast or flawless conferencing. VH2 prevents 
echo and distortion, and automatically adjusts caller audio to a uniform
 level, leaving you with a result that’s clean and clear. Plus, VH2 uses
 only VoIP phone lines, saving you money and increasing functionality. 
VH2 can even connect to many VoIP PBX systems.
Features:
Easy Hookup
VH2 can be configured in 
several ways to be compatible in environments where the studio has 
different telephone connection arrangements. Dual or single input and 
outputs can be selected, and AES3* or analog audio I/O can be chosen. 
VH2 can be configured for callers to hear each other, or be isolated 
depending on the needs of the studio. *Supports 48 KHz sampling rate 
only for AES3.
On-Hold Inputs
VH2 offers a 
pair of audio inputs for callers “on-hold”. This allows for listeners to
 hear your programming while they are waiting to be put “on-air”.
Consistent Audio Levels
Selectable
 automatic gain control (AGC) maintains a uniform audio output, even 
when the caller signal varies widely. Also, selectable caller ducking 
lowers incoming caller audio, so local talent remains in control.
Companion Phone
When
 configured with its companion phone (the Polycom IP 331), VH2 does even
 more. Calls can be answered on the handset and easily transferred back 
and forth to VH2, just like a traditional telephone hybrid. And the 
companion phone supports caller ID and outbound calling.
Status Indication
VH2
 is outfitted with front panel controls and status indicators so it can 
be used out-of-the-box. Front panel buttons can also be remoted via the 
rear panel connector, so your console buttons can trigger its functions.
