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.

OPTIMOD-FM 5500 puts coveted five-band and two-band OPTIMOD processing into a single rack unit package and brings it to you at the most affordable price ever.

Quality sound is what 5500 is all about-sound that attracts audiences by providing a polished, professional presentation regardless of format and source material. Exceptional versatility allows you to adjust the processor's audio texture to brand your audio, knowing that the resulting signature sound will remain consistent, cut-to-cut and source-to-source. Branding builds businesses and no other processors have the consistency to brand your sound like OPTIMOD.

With the 5500, your signature sound is just a preset away. An easy, one-knob Less/More adjustment allows you to customize any factory preset, trading cleanliness against processing artifacts according to the requirements of your market and competitive environment. Full Control gives you the versatility to customize your audio further. And, if you're a hard-core processing expert, you can explore Advanced Control to tweak presets at the same level as Orban's factory programmers. This versatility makes the 5500 a superb choice for any format. Its five-band processing is ideal for any pop music format (even the most competitive and aggressive CHR), while phase-linear two-band processing yields ultratransparent sound for classical, classic jazz, and fine arts formats. Regardless of your choice, 5500's optimized technology ensures unusually high average modulation and coverage for a given level of subjective quality. Unlike many lesser processors, the 5500 handles speech particularly well. It's always clean, even when you process for loudness.

If you're concerned about latency because you need to feed live talent headphones off air, be assured that the 5500's ultra-low-latency (5 ms delay) processing will keep the most finicky talent happy. Or use optimum latency (15 ms delay) processing for the most competitive sound with delay that's still low enough to satisfy most any talent.

Versatility doesn't stop with sound.

The 5500 can also be used as a superb stand-alone stereo encoder with latency as low as 2 ms and full overshoot limiting in both the left/right and composite baseband domains.

When used in this mode, the 5500 must be driven (usually via an STL) by a full-featured FM audio processor (like Orban's 8600) that incorporates pre-emphasis aware HF limiting and peak control. In both modes, the 5500's stereo encoder helps deliver a transmitted signal that's always immaculately clean and perfectly peak limited, with full spectral protection of subcarriers and RDS/RBDS regardless of the amount of composite limiting.

It is the ideal choice for network broadcasters who process with Orban's flagship OPTIMOD-FM 8600 at the network origination point and who need a processor at every transmitter to eliminate STL overshoots (using the 5500's stand-alone stereo encoder mode) and/or to process local insertions while also eliminating network STL overshoots (using the 5500's audio processor / stereo encoder mode). Moreover, the 5500's two modes make it easy for large government and network broadcasters to manage its inventory of spares because any 5500 can be used as a stereo encoder with or without audio processing.

Available in both modes, the built-in, defeat-able ITU-BS412 multiplex power controller allows the 5500's output to meet even the most stringent European government regulations.

A 10 MHz frequency reference input allows the stereo pilot tone frequency to be locked to GPS or another high-accuracy frequency standard. This improves the performance of single-frequency networks in areas where coverage of the transmitters overlaps.

The 5500's built-in stereo encoder, AES/EBU digital inputs and outputs, and analog I/O permit hasslefree interfacing to any broadcast plant, whether the 5500 is located at the studio or the transmitter. Tight band limiting to 15 kHz means you can use any uncompressed digital STL to pass 5500- processed audio from studio to transmitter without compromising on-air loudness - there's no need to use STL's having 44.1 or 48 kHz sample-rate.

The stereo encoder's stereo sub-channel modulator can operate in normal double sideband mode and in an experimental compatible single sideband mode (SSB/VSB) that is offered to enable users to compare and assess the two modes.

Analog Fallback to Digital control that allows Silence Sense to switch the active input from Analog to Digital if silence is detected in the analog input signal but not on the digital input signal. This function works vice versa as well on both analog and digital AES input. The silence sense parameters apply to both simultaneously and both detectors are available to drive the 5500's tally outputs and sending SNMP Traps/Alerts.

If you want to locate the 5500 away from the studio, you'll be pleased by its three separate remote control ports - GPI contact closures, RS232 serial and built-in Ethernet for TCP/IP networks. The serial and Ethernet ports are supported by the supplied 5500 PC Remote Control application. This Windows® 2000/XP/Vista/7/8 application allows you to do even more with the 5500 than you can do through its front panel, making remote control a pleasure.

5500 PC Remote software allows you to access all 5500 features and allows you to archive and restore presets, automation lists, and system setups (containing I/O levels, digital word lengths, GPI functional assignments, etc.)

Built-in clock-based automation lets you automatically day-part the processing. You can control many other 5500 operating parameters too.

The 5500's feature set fully exploits the processor's DSP and computer-based control architecture. To ensure absolute accuracy, you can automatically synchronize the clock to an Internet timeserver. It has a cool-running, energy-efficient switching power supply and uses the latest dual-core DSP chip technology from Freescale Semiconductor.

Innovation
The ARX COMPO? is a unique compressor/limiter designed for use in any
professional audio dynamics control application, packaged in a compact 1
RU chassis.The COMPO operates as two independent compressor/limiters,
with 'industry standard' variable Threshold, Ratio and Output gain controls.
A Stereo Link switch on the front panel lets both channels track as a stereo
pair in a Master/Slave configuration.
Enhance Switch
The COMPO features an 'Enhance' switch, which provides frequency restoration
to preserve the spectral balance of the audio signal, compensating for the sagging
Low and High frequency response of compressed program material.
The best way to think of it is as a 'smart' loudness control.
Wide Scale metering
There is comprehensive LED indication of all operating functions and status. Above
or Below Threshold LEDs on each channel give you instant visual confirmation of
compressor activity, as well as easy to read LED Gain Reduction meters.
Balanced Inputs and Outputs
