Control Input Pins
Preset Control
Figure 9 shows examples of how to connect different types of preset control hardware to the Control Input pins. When properly config-
ured, the P4800 changes to the appropriate preset in response to the switch.

* See Table 5 for resistor values. A two-conductor, unshielded cable,
such as a Belden 8442, is recommended. The total resistance of the
cable run must be less than 100 ohms.

PRESET RESISTOR VALUE
1
97 kΩ – ∞ Ω
2 44–60 kΩ
3 26–32 kΩ
4 17–20 kΩ
5 11.3–13.6 kΩ
6 7.8–9.3 kΩ
7 5.2–6.3 kΩ
8 3.3–4.1 kΩ
9 1.9–2.5 kΩ
10 0.63–1.1 kΩ
A resistor with a value within the specified
range switches the device to the
corresponding preset.
Processor Control
Figure 10 shows examples of how to connect a potentiometer or a switch to the Control Input pins. The P4800 can then be configured
to respond to the switch or potentiometer by changing gain settings or muting channels.

Figure 11 shows examples of how to wire Logic Output pins to LEDs or relays. You can then configure the P4800 to ground the ap-
propriate pins to reflect muted channels.

Figure 12 shows examples of how to wire Logic Output pins to LEDs, relays, or third-party logic hardware. You can then configure the
P4800 to ground the appropriate pins to reflect the active preset.
