Control-I/O connection terminal

14.1.1. Remote volumes 1, 2

Volume of the input or output channels can be remotely adjusted by connecting a variable resistor or variable DC power supply unit. (The REMT VOL 1 terminal is factory-preset to output 1, and the REMT VOL 2 to output 2.)

Connect a 10 k(linear taper) variable resistor or input the DC voltage of 0 to +10 V as shown on the next page.

The larger the variable resistor resistance, the larger the volume is, and the smaller its resistance, the smaller the volume is.

Connecting the ZM-9001 Zone Manager adds 6 control inputs and allows the equipped 6 control buttons to perform the functions assigned for input's or output's channel volume up/down, or Scene memory recall. Connecting the ZM-9002 Zone Manager adds 1 volume control and 4 control inputs. Volume of the input or output channels can be remotely adjusted with the volume control, and the 4 control buttons can be assigned the same functions as those of the ZM-9001.

14.1.2. Control inputs 1 – 4

Connect switch contacts, etc. to these terminals.

Open voltage is 3.3 V, and the short-circuit current is 1 mA or less.
