Power input: Power cord connection. Removing the power cord when the amplifier is on is an acceptable
power-down method.
w
Output Configuration DIP switches: Any mixed configuration of low and high impedance output loads
can be made using the four switches for each channel.
70V/100V: Switch the channel output operation between 70 volts and 100 volts.
Lo-Z/Hi-Z: Switch the channel output impedance between low impedance and high impedance.
35Hz/70Hz: Switch the high pass filter frequency between 35 Hz and 70 Hz.
HPF Off/HPF On: Activate or deactivate the channel output high-pass filter. Recommended for
70V/100V outputs if software bandpass high-pass is not engaged.
e
Output connector: An eight-terminal connector for loudspeaker connections. Each channel can deliver up to 300 watts (PSX1204D),
600 watts (PSX2404D), or 1200 watts (PSX4804D) of symmetrical power.
r
Remote Level connector: The level of each channel can be adjusted remotely by a remote level control (linear 10 kΩ potentiometer)
connected to the input LEVEL connector for that channel. Connect to Channel 1 and set CH1 MSTR DIP switch to On to control all
four channels from one controller. Alternatively, to enable remote level adjustment of two or three channels simultaneously, connect
the potentiometer's resistive variable pin to multiple channels in parallel (refer to the example diagram where the potentiometer is
controlling Channels 1–3). The remote level controls are in series with the Channel Attenuation controls.
Note: ControlCenter CC-1, CC-2, and CC-3 are not compatible with PowerShareX amplifiers.
t
Line Input connector: Line-level input for balanced analog audio signals.
y
GPI/Remote connector: Remote on and off control. Both pair of terminals respond to the differential voltage between the contacts: a
voltage difference between 5 VDC and 24 VDC triggers the control. Remote off can be used to mute the amplifier. The terminals act
differently depending on the actual state of the amplifier:

CAUTION: Any voltage exceeding 28 VDC may damage the input circuitry.
u
System Configuration DIP switches: DIP switches to control overall system output and performance.
Input Gain Selection

CH1 MSTR: When the CH1 MSTR switch is OFF, remote-level potentiometers work independently for each
channel. When the CH1 MSTR switch is ON, the remote-level potentiometer of Channel 1 acts as a master level,
controlling the volume of all four channels.
GAIN: Adjust the global input gain sensitivity to 35 dB, 32 dB, 29 dB, or 26 dB by following the configuration
diagrams on the rear of the amplifier. This feature is designed to match the voltage of the input signal.
PowerShareX amplifiers ship with gain sensitivity set to 32 dB by default.
Note: For most situations, leave this set to 32 dB gain. The 35 dB gain setting is similar to PowerMatch 8500N
(36 dB). Analog gain sensitivity cannot be further adjusted through ControlSpace Designer. Digital input
sensitivity can also be adjusted through ControlSpace Designer.
BRK SAVE (Breaker Save): Switch to ON when (1) the power grid is unable to provide enough current to
continuously drive the loads, or (2) when at least one of the amplifiers connected to the same outlet can reach
the critical power absorption of the line. When activated, the Breaker Save halves the maximum continuous
current absorption from the mains, which reduces the available output power. This will be indicated by the
LIMIT System Status LED on the front panel. This will affect overall performance of the amplifier.
NRG SAVE (Energy Save): The power supply unit allows a reduction in power consumption when the input
signal falls under a defined threshold. When ON, Energy Save is active on each channel independently. If the signal is absent for more than 30 minutes on all channels, auto
standby is applied and the main PSU is turned off to further conserve energy (Time out time is selectable via ControlSpace Designer). Normal operation resumes immediately
upon detecting a signal.
Note: USR A, USR B, and USR C (PSX4804D only) are unavailable.
2Ω: PowerShareX amplifiers are optimized for working with 4Ω output loads, but the 2Ω switch allows loads down to 2Ω. Switch to ON to activate an operating condition that
optimizes the performance with very low loads by limiting the maximum output voltage to 85 V
(i.e. in Lo-Z configuration). For optimal 2Ω performance, switch the Lo-Z/Hi-Z Output Configuration DIP to Lo-Z for all channels.
Note: PSX1204D and PSX2404D only. PSX4804D can also handle 2Ω loads without the use of a DIP switch.
i
Ethernet port: RJ45 connector. Remotely control the amplifier via an Ethernet connection through a personal computer and ControlSpace Designer software.
o
GPO/Alarm connector: There are general-purpose output connections for each channel: one Normally Open (NO), one Normally Closed (NC), and one channel number
connection that acts as a ground (1–4). At least two connections are required to report and detect a change (e.g., 3 and NC). When the amplifier is in normal operating
condition, the NO contacts are closed and the NC contacts are open. These contacts are toggled to indicate a potentially dangerous fault, unsafe operating condition, or any
fault preventing normal output channel operation, including the following:
No AC mains (i.e. system shutdown).
Across all channels:
Thermal stress: the system temperature is too high and the thermal protection is engaged.
Amplifier is in standby mode.
Affected channels only: Short circuit in output wiring: either the loudspeaker or the line is in short. Alarm is sent out the
specific output channel with the short circuit event.
NC/NO connections of multiple channels can be combined if needed. See ControlSpace Designer for additional alarm and monitoring options.
a
Dante port: RJ45 connector. PowerShareX accepts four input streams from the Dante® connection through the Dante port. Use a computer running Dante Controller to
implement a Dante network. Dante Controller is a software application that manages devices on the network.
