D&R's newest Telephone Hybrid-1 is an interface between a standard telephone line and a mixing console. Its purpose is to enable to record or broadcast a conversation between a caller and a presenter in an easy way.
Superb audio separation between in and outgoing signals are achieved by carefully designed internal circuitry. It is a problem solver for changing two wire communication into a four wire system with separate in and outputs.
Telephone hybrids provide the interface between professional audio equipment and the public telephone network.
They provide protection for your equipment and the public telephone lines, allowing for varying line signals and line conditions. Automatically canceling out the unwanted signal they also facilitate two-way communication down a single telephone line.
Each hybrid has a telephone line connection, a handset connection and separate connectors for audio input and output from a broadcast mixer, or other professional audio source.
A large proportion of D&R hybrids are used in radio and television broadcasting applications allowing external callers to be connected to the studio mixing console. Most of the other units are supplied to communication operations allowing extremely effective conversion between 4-wire audio circuits and standard telephone lines.
Specification

Axel Compact telephone hybrid BoxTel MKII
AXEL Compact telephone hybrid. Management of 1 wired PSTN / POTS line, electronically balanced input and output on XLR connector
Product Discription:
BoxTel MKII is an analogue telephone hybrid, designed to interface a telephone line with audio equipments. BoxTel MKII manages 1
POTS/PSTN line, whereas BoxTel GSM manages 1 GSM line to establish telephone connections where wired lines are not present.
A powerful internal microcontroller completely manages both BoxTel MKII and BoxTel GSM, allowing the configuration of the operating modes
via software. The internal microcontroller provides further functions such as adjustment of the line impedance according to the region,
visualization of the Send/Receive audio levels on the front leds, line detecting presence of a telephone line, buzzer with adjustable level,
AutoHook - automatic line hooking and answering after a certain number of rings. While BoxTel MKII is operative, its possible to exclude or
keep connected in parallel an external telephone set (Tel.Set).
The backlit Hook/Ring button on the front panel allows a quick management of the phone calls; each time a telephone call is incoming the
BoxTels Hook/Ring button starts to flash, by pressing it the operator answer the phone call. BoxTel MKII has the Line Detecting function,
which makes the Hook/Ring button switch on in presence of a telephone line.
BoxTel MKII and BoxTel GSM are devices equipped with an internal power supply enabling great audio performance: two separate
Send/Receive front potentiometers manage the audio level, with a total range of +/- 15dB. The input sensitivity is set at 0dBu while the
maximum output level is greater than +20 dBu.
The audio connections are separated for Send/Receive and are available over XLR electronically balanced connectors. A RJ11C connector
allows the telephone line connection (Tel.Line) and one more RJ11C connector performs the connection to an external telephone set (Tel.Set).
A GPIO port with optocouplers and open collector is provided to establish remote connections between BoxTel MKII and BoxTel GSM and
mixing console. It is possible to connect directly the Telco module of an Oxygen4, Oxygen5 and Oxygen7 console with BoxTel MKII/BoxTel GSM
by using a simlpe Pin-to-Pin cable. Internal universal power supply 90-264Vac/47-63Hz to operate worldwide.
Thanks to all of their features, BoxTel MKII and BoxTel GSM represent the telephone hybrids with the best quality/price ratio available on the
marketplace. BoxTel MKII and BoxTel GSM occupy ½ rack unit - LxHxD 22x5x13cm.

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.
