• SYSTEL IP does not operate on hybrids, but on a 4-wire digital matrix: all
the lines can intervene live and simultaneously without loss of quality.
• Significant cost savings can be obtained by connecting the entire system
to an Internet telephony provider, or as extensions of the IP PBX that is
already in service in the corporation.
• SYSTEL IP16 shares the IP lines in a very flexible and dynamic way with
up to 4 studios through very simple analog or digital cabling not having to
deploy special and expensive audio nodes. SYSTEL IP 16, also offers
many channels of local audio input and output through IP, in Dante
format, compatible with AES 67.
• It is possible to create much larger installation, with dozens of studios or
even for a whole network of broadcasting stations. In such scenario, each
SYSTEL IP16 will be a simple set of extensions and that can share
phonebooks and users.
• SYSTEL IP control terminals are extremely powerful, flexible, economical
and practical. We can use:
– An IP phone in order to make calls and talk to the remote party, as well
as a software application that can be installed on any PC.
– An IP phone with touch screen, in order to make calls and talk to the
remote party, running a specific embedded application.
• Several studios and work spaces can be defined. Multiple control
terminals with internal and individual labelling and chat lines can be used
in a studio, thus dividing the work among producers, technicians and
• Possibility to set the number of audio signals arriving at the studio
console, allowing for level adjustment either through this SW application
or the fader of the mixing console.
• There are applications with different layouts and functions available in
order to suit different types of operation.
TH-03 Digital Hybrids
TH-03 Digital Hybrids
Digital Hybrids with AEQ’s Frequency Extender incorporated.
The TH-03 is an advanced digital hybrid that comes in versions for 1 or 2 telephone lines, and either analog or AES/EBU digital inputs and outputs.
Each model has built-in signal level metering for each hybrid line. Feedback is automatically mitigated by the digital hybrid, and no adjustments or calibration required.
The two line models include a mix-minus bus for multiplex communication while on-air or on-hold in the studio: Pressing the MPX button automatically establishes a conference between the two telephone lines, so only a single audio feed to and from the hybrid to the mixing console is needed. The TH-03 takes care of simultaneously getting both in-bound calls to the console, and provides audio from the console back to each individual telephone line, with both console audio and the other callers audio.
The TH-03 also has AEQ’s exclusive built-in frequency extender. When activated, it moves all frequencies 250 Hz upwards on the send line and 250 Hz downwards on the receive line. This additional 2 ½ octaves results in enhanced bass frequencies. To use the frequency extender functionality, another AEQ hybrid must be used at the far end.
Each telephone line incorporates a SET port which is disabled when the hybrid is on-air. Each of the TH-03’s telephone lines Off-Hook, Frequency Extender, and On-Air functions can be controlled locally via the front panel, or remotely using a console or a remote control panel.
The TH-03 is capable of operating with single or dual lines. Independent outputs line level, or multiplexed output provided by its unique multiplexing capabilities. Working with dual lines permits telephone multiconference, allowing the On Air personality and two callers to talk and listen to each other simultaneously.
Feedback is eliminated by the digital hybrid. No adjustments required to operate.
