Output Connections
Speakers with total impedance of 4 to 16 ohms, or speakers fitted with a 70V/100V line transformer may be
connected. Always ensure that the total load of the speakers does not exceed the rated output of the amplifier
ie either 4Ω minimum for the 4-16Ω terminals or 20Ω minimum at 100V for 500W. Otherwise either the DC or
mains fuse could blow or the fault led activate and the amp will shut down. Always be careful to avoid short
circuits and connection to the wrong terminals.

24V 1A output
A constant 24V output terminal has been provided to power ancilliary 24V devices.
3
DC Resettable fuses
These fuses protect the internal power supply. If the fuses are tripped they are easily reset by pressing the small
buttons on the fuses.
4
24V Backup battery charging
The A 4395 amplifier includes a charging circuit so that a backup battery connected to the amplifiers 24V DC
Input can be trickle charged. The battery charger is connected to the battery internally when the link is fitted to
this connector (see Fig 5 for more details). The battery will be charged at approximately 300mA.
5
24VDC IN
Battery Backup: Provision has been provided to run the amplifier from a suitably rated 24V battery system in the
event of a mains failure. Using appropriately rated cable, connect the battery to the "24V DC In" terminals.
Observe correct polarity when connecting. (see Fig 5 for more details)
6
Input 1
This input can be either a balanced XLR input or dual RCA line input with adjustable input sensitivities of 100mV
or 1V. The line input dual RCA connectors are internally mixed to produce a mono input signal.
7
Input 2
This input is a dual RCA line input with adjustable input sensitivities of 100mV or 1V. The line input dual RCA
connector is internally mixed to produce a mono input signal.
8
DIP Switches
These DIP switches set the input sensitivities of inputs 1 & 2, enable the VOX muting and enable the phantom
power to the XLR input (see Fig 6 for more detail).
