Macrotel X1 & X2 MultimodeDigital Telephone Hybrid

POTS, VOIP, Bluetooth or GSM professional HD Audio hybrid

The new generation of Macrotel X introduces the AxelTech Multimode Technology.The internal framework based on DSP (Digital Signal Processor) allows to work in real time achieving the highest audio performance.This Technology sets Macrotel X1 Multimode and Macrotel X2 Multimode as cutting-edge equipment in the telephone interface technology and allows managing one or two telephone connections: POTS (Plain Old Telephone Service) landline, VOIP, Bluetooth or GSM (with optional interface). With Macrotel X2 Multimode any technology combination is possible.

Audio enhancement features are custom designed to guarantee the best quality in phone calls. Thanks to AxelTech's ten-year experience in the field of audio processing we should consider this product not a common telephone hybrid but a Telephone Audio Processor able to shape the sound to optimize the yield of every single phone call. In fact the new Macrotel X Multimode series integrate a powerful DSP system that takes care of the telephone signal process: 

  • Automatic Gain control (AGC)
  • Echo canceller
  • Hold caller/Attenuator
  • Expander and Compressor
  • Audio Limiter
  • 3 Bands Fully parametric Equalizer

The new Macrotel X Multimode range does not require the installation of any software: the unit has an integrated Web server supporting the most popular browsers (Chrome, Firefox, Explorer, Opera, etc.).A simple and intuitive GUI can be accessed through any device: PC, notebook, tablet, smartphone, etc.For services synchronization and logs the Macrotel connects to a NTP server. The main XLR input and output connectors can manage analogue or AES/EBU signals according to the device settings (AES/EBU input/output is optional).A second XLR analogue output is anyway available. In Bluetooth mode the two outputs act like a stereo balanced output.

Macrotel X Multimode is able to record the telephone calls audio on a USB flash memory plugged in the USB front panel slot.Audio will be recorded in PCM format with a self-explaining filename based on date/time and can include only the RX audio or both RX and TX signals.Moreover it’s possible to send an RTP-PCM audio stream to an external PC to record the call.This recording can include only the RX audio or both RX and TX signals. A multiple GPIO port allows to manage the device from external equipment, like audio console or PC.System sends “Ring”, “Hold”, “Hook” and “REC” status and manages “Hook”, “Rec”, “Mode” and “Hold” functions. On the front panel an audio meters with 18 LEDs shows the RX and TX audio level of each channel. Additional LEDs show working Mode and Power on.Power supply can be between 90 and 260 V AC - 50/60 Hz: this allows to use it worldwide.
