GENERAL FEATURES
BoxTel MKII is an analog telephone hybrid, designed to interface audio devices with a telephone line, in both directions, to and
from. BoxTel MKII manages a POTS/PSTN telephone line, while BoxTel MKII GSM manages a GSM telephone line, to establish
telephone connections where wired telephone lines are not available.
All the internal management of BoxTel MKII and BoxTel MKII GSM is carried out by an internal powerful microcontroller, thanks to
which the operating mode of the device can be configured via software. The other functions provided by the internal
microcontroller are: adjustment of telephone impedance according to the region, display of the
Send / Receive audio levels with
LEDs on the front, line detecting – detection of the telephone line, level of the buzzer with adjustable amplitude, AutoHook – auto
line hook after a certain number of rings. An external telephone set (Tel.Set) can be excluded or left connected in parallel when
BoxTel MKII is working.
The backlit
Hook/Ring key on the front panel offers a fast management of the call;
each time a call reaches the BoxTel MKII or BoxTel MKII GSM the Hook/Ring flashes, and when pressed the call is hooked and the
light stays on for the entire period in which the call is hooked. BoxTel MKII features Line Detecting , that switches on the Hook/Ring
key only when it detects a telephone line.
BoxTel MKII and BoxTel MKII GSM are devices that feature an internal power supply and this allows great audio dynamic range:
the two front
Send/Receive knobs control the audio level with a total range of about +/- 15dB. The input sensitivity is set at 0dB and
the maximum output level is greater than +20 dBu.
The audio connections are divided into
Send/Receive and are available on electronically balanced XLR. A RJ11C connector is
available to connect the telephone line (Tel.Line)and a RJ11C connector is available for the connection to an external telephone set
(Tel.Set).
A GPIO connection port with optocouplers and open collector is available for remote connections with BoxTel MKII and
BoxTel MKII GSM. The Telco module of a Oxygen4, Oxygen5 and Oxygen7 console can be directly connected by means of a Pin-to-
Pin a BoxTel MKII/ BoxTel MKII GSM cable.
Internal universal power supply 90-264Vac/47-63Hz to operate in any part of the world. The dimension of the devices is 22x5x13cm
and they take up ½ rack unit. BoxTel MKII and BoxTel MKII GSM, with all their functions, are the telephone hybrids with the best
quality/price ratio available on the market.
