Communicating Directly Between Control Heads (Intercom)
Intercom
is the function to directly communicate (simplex communication) between Control Head 1 and Control Head 2
with a wired connection. The function is for Dual Control Head. This function is used as means of contact between 2 Control
Heads when the Control Heads are at remote locations.
Pressing the
PTT
switch of a Control Head when
Intercom
is on emits the audio from the speaker of the other Control Head.
Intercom
can be toggled between on and off by any of the following key operations:
1. Pressing the
Intercom
key toggles Intercom between on and off.
2. Entering Menu Mode by pressing the
Menu
key, and then executing “Intercom” can toggle
Intercom
between on and
off.

The audio input to a Control Head is returned on KRK-15B via KCT-71, and is emitted from the other Control Head.
Therefore, only the Mic Line is available as the Modulation Line when
Intercom
is used, and the audio is not input from
MI2 of the D-sub 25-pin connector.

If audio is received when
Intercom
is on, the received audio is emitted from Control Head 1 and Control Head 2. The
received audio is also emitted from the external speaker connected to each RF Deck.

Intercom
turns off if a Zone-channel is changed, the Selected RF Deck is switched, or scanning is toggled between on
