When you want to present, broadcast, or record a telephone conversation, you need a device to process the phone call and present it to the console, as well as to separate "send” audio from the "receive” audio on the call. If send and receive audio aren’t isolated, it will result in an echoey, muddy sound - not to mention, annoyed listeners.
As many major markets are shifting from traditional phone lines to Voice-over-IP (VoIP) systems, the digital hybrids that could have performed this job in the past are becoming outmoded. Radio stations need a VoIP hybrid to ensure on-air and recorded phone calls sound beautiful.
A dual-line hybrid, VH2 connects two VoIP lines 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 VoIP phone lines, saving you money and increasing functionality. VH2 can even connect to many VoIP PBX systems.
Main Features: Audio Processing and Performance: • Prevents echo and other artifacts • G.722 codec support for wideband calls. Also supports G.711 • Receive filter reduces telephone line noise • Selectable automatic gain control (AGC) maintains a consistent audio output, even when the caller signal varies widely • Selectable caller ducking lowers incoming caller audio so local talent remains in control of the conversation • Can be configured to automatically answer and disconnect incoming calls
Operation: • Easily segue from caller-to-caller • Separately selectable single-ring auto-answer function for assisted or unattended operation • Handy front panel controls and status indication • When used with companion VoIP telephone, calls can be answered on handset and easily transferred back and forth to VH2 • Hybrid on/off controls and status remotable via web or contact closures • Send and caller level indication • Easy call conferencing • Dual "On-Hold” audio inputs to send program to callers on hold • Auto-Switching External Power Supply • Compliant with worldwide regulations, including FCC, CSA and CE
Audio Configuration: • Configure for separate caller outs of single caller mix • Configure for separate send feeds or single • Pro level, balanced audio I/O in XLR • Selectable AES3 I/O
IP Features: • Web-based configuration for the VoIP phone line setup, making it easy to adjust settings remotely from a browser • Transfer calls back and forth to many PBXs, or use optional companion extension VoIP phone • Ability to engage or drop or dial calls via web page • Companion phone - easy to move calls between handset and hybrid with the touch of a button

The Avalon VT-737SP features a combination of TUBE preamplifiers, opto-compressor,sweep equalizer, output level and VU metering in a 2U space. PREAMPLIFIER The VT-737SP has three input selections: 1. The VT-737SP features a higher-performance microphone input transformer with +48v phantom selection. 2. Instrument DI high source input with jack located on front panel. 3. Balanced line input, discrete high-level Class A. The Class A preamplifier utilizes two cascaded, dual vacuum tube triodes configured with minimum negative feedback. A high gain switch boosts the overall gain of the preamplifier. The four high quality tubes are configured as singled ended anode coupled followers. A passive-variable high pass filter and hard-wire relay bypass completes the input signal conditioning. The phase reverse relay is available on all three inputs. OPTO-COMPRESSOR The opto-compressor features a minimum signal path design with twin Class A vacuum tube triodes for gain matching. The optical attenuator acts as a simple passive level controller. Full dynamic control from soft compression to hard- knee limiting can be achieved with threshold, ratio-compression, attack and release controls plus gain reduction selection on the large VU meter. Special spectral control including de-ess is available with the dual sweep mid EQ to side- chain switch. The EQ section can be flipped pre or post the opto-compressor via a front panel switch for alternate effects and tone shaping. Two VT-737SPs can be linked via a rear panel link cable for stereo tracking. The compressor bypass is a sealed silver relay for the most direct signal path. SWEEP-EQUALIZER AND OUTPUT LEVEL The VT-737SP equalizer utilizes 100% discrete, Class A-high-voltage transistors for optimum sonic performance. The high and low frequency bands provide the smooth characteristics of an all passive design, while the dual mid bands include variable frequency and switched Q-width selection. The enhanced range of the mid bands is extended into the high and low bands by the use of X10 frequency multipliers. The bypass switch incorporates a sealed silver relay for the most direct signal path. When the EQ to sidechain is engaged, the high-low EQ remains in the audio path for "tone enhancement“. The output level control provides a variable control of the overall signal path. The output amplifier utilizes another dual triode vacuum tube driving a 100% discrete, Class A, high-current, balanced and DC coupled low noise output amplifier. AVALON VT-737SP FEATURES Vacuum tube triode signal path, transformer balanced microphone input, high-voltage circuits for maximum headroom to +30dB, low noise -92dB, internal discrete power supply with toroidal transformer, soft-start tube life extender, stereo link for compressors, all discrete Class A equalizer with musical passive filter design, sealed silver relays for signal routing, large control knobs with professional conductive plastic potentiometers, VU meter for output level monitoring and compressor gain reduction.
