audio for many years.
PASSIVE-ACTIVE FILTER DESIGN
Avalon equalizers feature the unique combination of both active and passive filter EQ designs.
This special combination enables the AD2055 to deliver high speed transient detail at the
operational extremes of real-world equalization demands. The passive high and low bands offer
alternate musical tone range to the full function active parametric mid bands. Passive equalizers
have long been a favorite with music lovers around the world. Full bodied, powerful (up to +/-32dB,
64dB range !) and sweet frequency selections are the benefits of the passive high-low EQ bands.
The full bandwidth twin mid bands provide variable frequency selection (X10 frequency multipliers
for very wide range), variable Q (width) and amplitude control.
MINIMUM SIGNAL PATH DESIGN
Avalon's advanced true symmetry design offers high-voltage, large headroom, extended bandwidth
and very low noise. The use of 100% discrete, Pure Class A signal amplifiers give the serious music
professional unlimited sonic character and a natural harmonic detail that enhances the program
material and becomes one with the music itself. The Avalon AD2055 breathes life!

Features Four Independent Compressor Channels Channels 1 and 2, 3 and 4 are stereo linkable 7 LED Gain Reduction metering Balanced XLR Inputs and Outputs Sidechain Insert points Intuitive, user friendly layout Flawless performance The sheer amount of effects and signal processors necessary for today's standards of audio production puts a great strain on the available space in equipment racks, both in the studio and on the road.So, ARX would like to introduce the ARX Quadcomp. An all-new upgrade of the classic award-winning ARX Quadcomp?, the very first four channel 1 RU compressor.You?ll notice that we haven?t strayed very far from our original design concept. The Quadcomp is still four variable ratio Compressor/ Limiters neatly housed in a compact all steel 1 RU package. However, all new low noise/low distortion circuitry, better metering plus XLR inputs and outputs put the Quadcomp in a class of its own. More Control, Less Space On the front panel, each channel has the 'industry standard' individual controls for Threshold, Compression Ratio and Output, plus a new 7 LED Gain Reduction display for accurate visual indication of the amount of gain reduction being applied to the program, and an IN/OUT hardwire bypass switch.In addition to this, each channel has a blank numbered panel to write on for easy confirmation of compressor assigns. Precision Circuitry Internally, each compressor uses Class A VCAs and true 2 pole averaging RMS/DC converters for low distortion and accuracy, plus program dependent attack and release time, which automatically determines optimum compressor response. Balanced Inputs and Outputs The rear panel has true differential Balanced XLR Inputs and Outputs for each compressor. Each compressor has a TRS jack Sidechain access insert point, for frequency sensitive compression, De-essing, etc. in conjunction with an external equalizer (such as the ARX EQ260). Compressor pairs 1 and 2, 3 and 4 also have rear panel mounted Stereo Link switches for accurate stereo tracking. When switched IN, the first channel becomes the master and controls all the functions of the second except Output gain. Universal AC Power AC power range is switchable 100 to 120V, or 220 to 240V, and is connected to the unit via a standard IEC connector, with built-in fuse and voltage switch. Whatever the application ? Channel insert, Bus insert, Master Outputs, Monitor outputs, Crossover outputs, the Quadcomp II?s unique High Density design, precision Low Noise circuitry and clean uncluttered layout make it a truly useful audio tool for all applications.

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.
