This method brings impedance matching and level matching, but no source-receiver iso-

lation. Use a resistor network to passively attenuate the XLR signal from 3.1 V down to

0.42V and change the impedance from 110 Ω to 75 Ω.

Connecting multiple KH 120 D loudspeakers together

Use the AES3 OUTPUT socket B and INPUT socket C. T-pieces are not required – see

picture below.

Make an appropriate setting (“DIGITAL A” or “DIGITAL B”) on the SIGNAL SELECT

rotary switch D.

End of the line external termination is not required as the AES3 INPUT socket (BNC) C

already has an internal 75 Ω termination.

DIGITAL A+B Digital subframe A summed with digital subframe B

and a 6 dB attenuation, AES3 INPUT socket C

Each of these can be selected with and without delay added, so it is very quick to bypass

the delay.

The digital output is a copy of the digital input signal which can be used to feed the

digital signal onto other loudspeaker or products. There is no digital output from the

AES3 OUTPUT socket (BNC) B when an analog signal is connected to the ANALOG INPUT

socket6, therefore the KH 120 D cannot be used as an analog-to-digital converter.
