2.3.3 External Speaker (KES-5: Option)
The speaker output is as follows:
(1) The external speaker output from the connector (9-pin) for
accessory on the front of the NX-5700HB is 12 W / 4 ohm.
(2) The KCH-20R Remote Control Head does not have a built-
in speaker. By connecting the KCT-72 to KCH-20R, an
external speaker can be connected. When using the KCT-
72, the speaker output from the KCH-20R is 3 W / 4 ohm.
Note:
Since the radio uses a BTL audio amplifier, do not ground
the speaker output pin.
2.3.3.1
Connecting the KES-5 to the accessory connector
(9-pin) of the NX-5700HB
(1) Connect the speaker lead of KES-5 to the Socket (9-pin)
NX-5700HB accessory.
Insert the black and white stripe speaker lead into hole pin
2 of the socket (9-pin), and black lead into hole pin 6 of the
socket.
(2) Connect the socket of KES-5 made in step (1) to the
connector (9-pin) for accessory on the front of the NX-
5700HB.
2.3.3.2
Connecting the KES-5 to the KCH-20R
When connecting the KES-5 to the KCH-20R, the KCT-72
connection cable is used.
(1) Connecting the KCT-72 to the KCH-20R is same as
"2.3.2.2 Connecting the KCT-18 cable to the KCH-20R
Remote Control Head". Refer to the "2.3.2.2 Connecting
the KCT-18 cable to the KCH-20R Remote Control Head".
(2) Connect the speaker lead of KES-5 to the socket (12-pin)
KCT-72 accessory.
Insert the Black/White lead into hole pin 10 of the socket
(12-pin), and the Black lead into hole pin 11 of the socket.
(3) Connect the socket of KES-5 made in step (2) to the
accessory connector (12-pin) of the KCT-72.
2.3.3.3
Use as public address speaker
The 20W PA (Public Address) voice signal is output from pins 7
and 8.
(1) Connect the lead wire of the KES-5 to the Socket (9-pin)
NX-5700HB accessory.
Insert the black and white stripe lead into hole pin 7 of the
socket, and the black lead into hole pin 8 of the socket.
2.3.4 Horn Alert Function
Installation procedure for the Horn alert function (maximum 2A
drive).
Connect the car horn warning control signal with the 4 pin and 5
pin of the Socket (9-pin) NX-5700HB accessory.
The Horn alert function is turned on / off by the FET switch circuit
inside the radio.
Horn alert function can be controlled by signaling decoding.
This switch is the FET switch of P-channel type.
Therefore, a DC power supply is necessary to use the HR1.
The voltage range is from 5V to 16V. The maximum current is
2A.
Pay attention to the input and output of the Socket (9-pin) NX-
5700HB accessory.
