Voice Quality Restoration

The optional 2330 module allows using VQR technology for all the telephone hybrid signals, included external hybrids. It means to restore the cuasi-original voice quality that is impaired during a telephone or cellular communication.

Headroom

22 dB @ LIN to PGM Ref + 4dBu/10 k

Digital control bus

One Start Devices output for each input module, to start external devices when open each channel fader.
This allows to control Virtual Rack processors and start audio devices.
One Digi-Solid bus input for each line module, when using 2320 digital module. Allows to control the fader for Radio & Satellite Automation, from the PC

Frequency response

20-20.000 Hz +/- 0.25 dB (LIN or MIC to PGM)

Noise

MIC input, EIN=-132 dBu/150 ohms
LINE input, S/N > 95 dBA

Dynamic Range

From Line to PGM > 110dBA (Better than CD quality)

Crosstalk

PGM-AUD-SEND > 90 dBA @30-10.000 Hz
L-R & R-L > 90 dBA @ 1khz

Distortion

From AES/EBU digital input to PGM, less than 0,001% (24 bits quality)
From analog LIN input, using 2320 module, less than 0,002 %
From standard LINE to PGM out < 0.02 % THD @30-15.000 Hz. From MIC to PGM out < 0.02 % THD @30-15.000 Hz

Phase

From Line to PGM, < 2º L&R @50-10.000 Hz

Stereo Tracking

Below 0.2 dB error L/R in fader range 0 to 40 dB

Telephone Hybrid Specs

3 Hybrid inputs, 2 for phone lines and one for cellular phone (full duplex)
It includes a mini-PBX with Ringer, Line attention with free hands operation, and Line Transfer
Frequency Response: 250 – 4.000 hz
Noise: > 60 dBA S/N
Rejection: > 40 dB rejection
Rejection adjust: quick Test Mode to adjust the hybrid balance without disturbing On-air operation.
Preference atenuator: 10 dB local speaker interrupt priority; it can be disabled with internal jumper.
Automatic On-Air logic: Audio & Logic are managed from a single 100mm slide fader that performs all the operations in error-free mode (CUE= private hands free Talk; Hold with AIR return & Live On Air)

Telephone input lightning discharge safety

Telephone Hybrid inputs are transformer floating to meet the Public Telephone service isolation standards. They are protected with SIOV Varistors against lightning discharges. And are factory tested to 2.000 volts capacitor discharge according to Siemens/Ramatel 44.04 standard

Talkback Microphone

Included Talkback MIC, with Automatic Level Control. Noise Cancelled PZM type. Outputs to Phone Line Hybrid and Studio Speaker with AutoSwitch (AutoSwitchs allows one-touch two way Studio communication)

Studio BOX

D9 connector at rear side for optional Studio BOX that manages 5 headphones with individual levels, Timer & Clock, active studio loudspeaker level, Tally light and Talkback

Distorsión en 2300 digital

Espectro de la salida de la consola 2300XL con una señal senoidal de entrada de 1kHz en archivo WAV en el Hard Disk de PC.
Reproducida con placa DSP 48 por la entrada AES/EBU 44.1 kHz del módulo 2320 de la consola
Puede verse que las armónicas son del orden de 0,001 %
es decir muy por debajo del límite de audibilidad del oído humano.

Esto incluye no solamente la consola sino el proceso de grabación/reproducción en Hard Disk !
