panic mute switch
4.6 - panic mute switch
At the rear of the amplifier the device is equipped with a 4-pin Euroblock connector dedicated for a
standard panic mute switch. The mute switch function provides d:series users with a hardware-based
mute option for all amp channels to minimize any possible causes of damage in sensitive situations.
The functionality of the panic mute system is based on opening and closing a power circuit.
Closed circuit:
normal operation of the device (not muted by hardware)
Open circuit:
panic mute is active (the device is muted by hardware; all channels are hard muted)
By default the d:series amplifier is supplied with a bypass connector for a closed circuit.
Function of the provided bypass connector:
To establish a closed power circuit the positive terminal (pin 1) is connected to
the negative terminal of the integrated current source (pin 4) and the negative
terminal (pin 2) to the positive terminal of the integrated current source (pin 3).
Pin assignment as labeled on the connector:
pin 1: positive terminal
pin 2: negative terminal
pin 3: positive terminal (from integrated current source)
pin 4: negative terminal (from integrated current source)
Setting up an optional panic mute switch
To use the panic mute function a switch has to be connected between the
positive terminal (pin 1) and the negative terminal of the integrated current
source (pin 4).
Setting up an optional panic mute switch for multiple amplifiers
Connect the desired amplifiers in series as shown in the graphic.
Because of the capacity of the integrated current source, you should not
connect more than five cascaded devices. For using the panic mute function
with more than five devices, we recommend using a multiple switch.
NOTE: Never apply an external voltage to the connector!
