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.

Compressos Expander Gate Kimiter DBX 166XS Stereo Overview Bring a more professional sound to your mix Adding a dbx® 166xs Compressor/Limiter/Gate to your live sound rig or studio gives you more dynamic control to help create a more polished, professional sound. Having compression in your audio chain gives you the ability to smooth out uneven levels, add sustain to guitars and fatten up your drums. It also makes it easy to bring vocals to the front of your mix - adding greater clarity and making them stand out from the surrounding instruments. To protect your expensive amps and speakers the PeakStop® limiter provides an absolute ceiling for peak excursions or large transients that could damage your equipment. dbx knows compressors...after all we invented them! The 166xs is the latest in a long line of the world's most successful compressors from the inventors of the technology. Its patented Overeasy® compression technology provides smooth and musical performance while the AutoDynamic™ attack and release controls, found only on dbx compressors, puts great sound within easy reach. The 166xs can operate in stereo or dual-mono modes, has true RMS power summing and features quality XLR and 1/4" TRS inputs and outputs. It cuts no corners on visual feedback with gain reduction metering and easy-to-read backlit switches. Specifications

In today's recording and sound reinforcement environments, the need for multiple channels of high quality, easy to use compression is growing rapidly. The new dbx® 1046 is designed to provide the audio professional with just that: 4 channels of great sounding dbx compression for a variety of applications. Incorporating the industry standard dbx designs and the latest available manufacturing techniques, the dbx 1046 provides pristine sonic quality with that classic dbx sound.

The 1046 provides 4 channels of smooth classic dbx OverEasy® or Hard Knee compression that are perfectly suited for use on individual tracks of your multitrack recorder, and in virtually all applications the separate channels can be individually interfaced and used for entirely independent purposes. Additionally the newly developed PeakStopPlus™ is ideal for protecting your system from the oppressive peaks that can take out valuable drivers in your sound reinforcement rig or studio monitors.

All four channels have the following controls:

Threshold - allows you to set the level at which the compressor starts affecting the gain

OverEasy - allows you to select between soft compression for overall gain control or Hard Knee compression based on the characteristics of the original dbx 160.

Ratio - allows you to set the slope of gain reduction affecting the signal over the threshold level.

Input/Output Meter - allows you to set the meter to check the input and output levels for maximum signal-to-noise ratio and best level matching.

Output Gain - allows you to add make-up gain or to adjust the output level for that channel to match the next device's input gain.

Bypass - hard wire bypass allows you to hear how the compressor is affecting your signal.

PeakStopPlus - allows you to set the maximum signal level you want to pass through this channel. While it's virtually impossible to eliminate distortion, the PeakStopPlus circuit does it gracefully and effectively with minimal distortion.

Stereo Link - allows you to link channels 1&2 and 3&4 for two channels of true stereo compression.

All four channels feature balanced gold plated XLR and 1/4" inputs and outputs, and switchable +4dBu or -10dBV operating level to interface each individual channel with any other device.

So whether you need to control the level, placement in the mix, or overall characteristics of 4 independent signals or control the gain leveling on a couple of stereo pairs, the dbx 1046 is for you.

 

  • Four independent channels of operation, stereo linkable in two pairs
  • PeakStopPlus™ limiting control for setting maximum allowable level regardless of compressor settings
  • Independent Threshold and ratio controls
  • Switchable OverEasy® or Hard Knee compression
  • Classic dbx® compression
