HPF menu to set High Pass Filter of the audio signal. Different filters are available (FLAt means
no filter)
Mic Mode menu set the audio mic connection.
Following Mic mode can be setup:
• 2W (2 wires): (PTT is possible) for external audio input
• 2W+B (2 wires + bias): (PTT is possible) for most 2 wires MIC
• 3W (3 wires): (no PTT) for most 3 wires MIC
• AUX: high impedence input
NOTE: MTP61 is not compatible with PHA60 phantom adapter.
PTT menu allows to configure the behaviour of PTT accessory when it is pushed.
If PTT is set to Mute, the audio is muted when the Push to Talk button is pushed.
If PTT is set to ON, Wisycom receiver is able to do an audio routing according to Tone squelch
matrix set on the receiver (see receiver user manual for more details).
Limiter to enable or disable the limiter function. Whem limiter is anable and the audio input
level is too high (level on the audio bar arrives to the peak) the transmitter adapt acutomatically
the audio level to avoid distorsion.
Cal. tone to activate the calibration tone.
The CALIBRATION TONE function generates a tone at specific frequecies (400Hz or 1000 Hz) at
-20dB level on the audio input.
Calibration tone Example – DPA 40xx would typically use 2W+ for 2 wire plus bias giving the 5V required for the
mic. A good starting place for this could be -6dB for starting with an interview. This setting allows for a range from -40dB
to +26dB
Example – Instrument typically for use with instruments that have a higher output level. Suggested starting gain is -23dB.
