ART - PS8 PRO
Professional Power Sequencer
OPERATION MANUAL
INTRODUCTION
The PS8 PRO provides controlled power sequencing to 8 rear AC outlets. Each output is delayed by a fixed amount that is determined by the front panel
Sequence Delay control. This allows you to control the power up and down sequence in a system to minimize turn-on transients and the damage that they may
cause. Sequencing power on also smooths out inrush currents. Remote switching is also provided for via a rear mounted Remote connector, handy when you
want to keep noisy or hot equipment in one room and control power remotely.
The PS8 PRO is also a full-featured power conditioner with Advanced Power Filtering, fast acting breaker, EMI and RFI filtering, as well as surge and spike
protection to protect your system. Additionally, a front panel LCD display gives you a constant read of AC line voltage and load current as well as a built in
system clock. The PS8 PRO is designed to sequence and protect a wide range of equipment from sensitive tube preamps to powered speakers, large displays,
or digital systems. Your equipment will sound and work better and live longer.

OPERATION
POWER SWITCH
The PS8 PRO has a master POWER switch for the rear outlets. This switch glows when the unit is enabled. If the rear REMOTE is not being used, turning on
this switch initiates a power on sequence for the rear outlets. Turning off the switch initiates a power off sequence and the rear outlets are then sequenced off.
CH1-CH8 LED INDICATORS
The CH1-CH8 LED indicators, on the front panel, indicate the current power (on/off) status. If power is available at a rear outlet then it’s corresponding front
panel indicator will be lit.
SEQUENCE DELAY
The front panel sequence delay control allows you to set the delay time between activation of each outlet. Its range is from 0.5 to 2.0 seconds. If set to 2.0
seconds, for example, there will be a 2 second delay between each outlet turning on or off in the sequence (16 seconds total delay from initial power on to CH8
power on). This gives you a wide range of control when setting the application of power to your system, thereby minimizing any unwanted effects.
REMOTE SWITCHING
The rear panel REMOTE connection block allows for external control of the power on and off sequence. If there are no connections to this block then the PS8
functions normally with all sequencing initiated by the front panel power switch. Connecting the REMOTE and GROUND terminals together at this block initiates
a power off sequence and all rear outlets are held in the OFF position. Once this connection is removed the PS8 PRO will sequence the rear outlets back on as
long as the front panel power switch on. This allows you to run a simple 2-wire low voltage (+5Volt) connection to a remote switch or relay to remotely control the
system. Useful for fixed install, conferencing, multimedia systems, recording studio/control rooms, and central control of equipment on stage in a live venue. A
status indicator terminal, with internal 1K-Ohm resistor connected to +5Volts, allows for direct powering of a remote indicator LED (if required). A +5 Volt terminal
is also provided to power an external relay or other control circuitry (if required). The following diagrams give just 2 examples of how you would connect.
