Active Hybrid with send and return gain, auto-adjusted by audio limiter and AGC. Balanced telephone
lines floating with ground isolation by Nickel-Ferrite transformers.
VQR System to improve the audio quality of telephone lines (HL203-VQ).
Constant level to console, independent from line level due to the action of the internal AGC. A 15 dB
phone level change causes less than 3 dB change at the Output
Output level control on the front panel. Nominal level +4 dBu, variable between -60/+8 dBu
Priority: The speaker at the Studios have priority over the caller, causing an attenuation fo 12 dB on
the incoming call.
HL202: 2 lines in conference with croosed gain. The 2 inputs for land lines or wired cell phone, are
isolated and floating with transformer.
HL203-VQ: Adds a third line through a cell linked by Bluetooth to avoid physical connections and
allow up to 10 meters away. The cell phone can be operated from HL203, receiving calls.
Band-Pass filters in send channel, limits response to 400 – 2.200 Hz to eliminate on-air sound
coloration.
Audio limiter to operate with signals from -5 to + 8 dBu.
Nominal + 4 dBm balanced 600 ohms or hi Z
Adjustable level with needle Vumeter.
Symetric output with XLR-3 connector.
0 dBm +/- 1 dB, measured over 2 KM artificial phone line
250 - 3.400 Hz +/- 1 dB (VQR off)
VQR on (HL203): improve the spectrum between 50 – 12.000 Hz
GAIN Adjustable until 30 dB
Lower than 0,2 % at the console output at 1 kHz
S/R better than 75 dBA, measured over 2 KM artificial phone line, with
without VQR
Better than 40 dB @ send of +4dBu at 1 Khz. Measured over 2 KM artificial phone line.
15 wheels preset for each line.
Protection against overshoots with varistors SIOV (Siemens). Resist discharge capacitor charged to
2,000 V in laboratory tests
Independents inputs, balanced and floating with transformer Isolation 250 V/CA
220/115 V, 50/60 Hz with manual switch. 10 VA
19" Rack mounting 1 U height
