Glensound Atomic Copper 29/T Twin Rack Mount Digital Hybrid

About: Glensound Atomic Copper 29/T Twin Rack Mount Digital Hybrid

Copper 29/T Overview: 

Glensound invented the worlds first hybrid in 1966 for the BBC. Current technology, combined with the Glensound Engineers understanding of digital systems for audio, have presented the environment to develop the ultimate telephone balancing unit. 

Glensound presents the Copper 29/T as part of the Atomic range, as it is considered to excel in its application.  This is a twin hybrid.  The points below are per each individual hybrid.

Analogue and Digital I/O:
The maximum flexibility is offered with analogue and digital audio connections

Twin DSP Processing and Control:
Two digital signal processors are used in the Copper 29 to allow dedicated control of the very important echo cancellation routines in one, whilst employing a second that is dedicated to the input/output process.

Compressor and Limiter - DSP1:
The incoming audio into the Copper 29 must be at the correct levels to start with. DSP1 manages the incoming analogue and digital audio with compression and limiting so as to not overload the telephone line.

Automatic Gain Control - DSP1:
Our automatic gain control maintains a constant caller level on the Copper 29 output making it easier to manage for the studio.

Automatic Caller Ducking - DSP1:
If there is an incoming audio signal into the Copper 29 from the studio, then the caller level will be ducked. This is to stop the caller talking over a presenter.

Band Pass Filters - DSP1:
Incoming and outgoing audio is put through band pass filters to remove unwanted artefacts.

The World's Finest Echo Cancellation Algorithm - DSP2:
Our impressive separation figures are a result of our dedicated echo cancellation system developed by the Glensound Digital Design Team.

Internal Mix Minus Generation - DSP2:
A second algorithm in our echo canceller produces an internal mix minus.

Intelligent Sample Rate Converter:
Our CPLD device manages sample rate conversion and removes any unnecessary delay.

Worldwide Line Impedance Matching:
A DAA device optimized for voice applications is used to match worldwide Impedance variations on analogue telephone circuits. 

PPM Meters:
Both the input and output have an 8 bar LED PPM meter.

Adjustable Level Control:
The input and outputs both have adjustable level control.

Auto Answer:
When selected, the auto answer function answers an incoming call after a preset number of rings.

Remote Control:
System control is available via a rear panel dsub 15 connector. This contains RS232 and 8 loops. RS232 gives you full setup and system control, where the loops give you on/off hook, divert, and 4 audio switches.

Handset Interface:
RJ11 connection to an external telephone for dialling.
