Echo Tail:
this is the value in ms of the Echo that is eliminated by the
PhoneX DSP. It is used together with the
Echo Cancelling
command
that controls the cancellation speed of the Echo on the telephone line.
This parameter acts on an automatic variation filter to cancel the echo.
The operating parameters self-adapt to the status of the line, of the input
and output levels. The variable parameters are the maximum
recoverable echo delay (16ms or 32ms) and the intervention modes
(OFF, FAST, NORMAL, SLOW)
Hook Mode:
this is the Telephone hybrid answering mode, which can
range from
Manual,
i.e. Off-Hook (answer) only when a call is answered
manually, to
Auto Off-Hook after n rings,
i.e. the automatic answering
of the Telephone Hybrid after n rings. The number of rings available is: 1
– 2 – 3 – 4 – 5
Line Sensitivity:
this is used to adjust the input gain from the telephone
line from -6dB ÷ +6dB.
Line Input Filter:
this is a high-pass filter (HPf) placed on the telephone
line in order to adapt and improve as much as possible the incoming
audio of one’s phone. Range of allowed values:
from 100 Hz to 350 Hz in 50Hz/steps
Line Output Filter:
this is a low-pass filter (LPf) placed on the telephone line in order to adapt and improve as much as
possible the incoming audio of one’s phone. Range of allowed values: from 2.6 kHz to 5.0 kHz
Line Type:
this command is used to select the telephone line to connect to the Telephone Hybrid. The PhoneX can be
connected to a 2Wire POTS / PSTN line with RJ11 plug (two-wire) or to a Wireless line through the connection of an
external
GSM
module. This command is used to select which line to use,
2Wire
or
GSM
. The
2Wire
line and the
Wireless
GSM
line cannot be used at the same time on the same Telephone Hybrid.
Accept External Commands
: by flagging this checkbox PhoneX is enabled to accept or not accept commands received
on the GP In and GP Out (SubD 25p) ports.
Denoiser Module:
this section is made up of three parameters On/Off,
Threshold and Expander Ratio. ON/OFF activates or deactivates the
Denoiser section of the DSP audio processing. The Threshold
parameter is used to select the level above which the Denoiser module
is triggered. The Expander Ratio is used to set the ratio of the sound
dynamic expansion range in relation to the DSP Denoiser Module.
Allowed values of the Denoiser Module:
-
Enabling/Disabling (with hard-off bypass)
-
Threshold: -60 dB ÷ -20 dB
-
Expansion ratio: 1:1.0 ÷ 1:2.0 in 0.1 steps
AGC, EQ, DUCKING:
Section made up of three parameters: AGC,
Equaliser and Ducking/Attenuation.
AGC
&
AGC Speed
: this is the maximum gain value of the Automatic
gain Control (AGC). The parameters that can be set are the maximum
gain (from +1dB to +12dB) and the variation speed (from OFF (0dB/s)
to 2dB/s, in 0.1 steps), i.e. by how many dB per second the signal level
is increased (gain).
High Eq
&
Bass Eq
: these two parameters act directly on the two-band equaliser inside the PhoneX audio processor.
The gain that can be set ranges from +0.0dB to a maximum of +8.0dB. The equaliser frequencies are set at 300Hz Bass
Eq and 2kHz High Eq.
