ART - PS8 PRO

Professional Power Sequencer

OPERATION MANUAL

INTRODUCTION

The PS8 PRO p

rovides 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 PR

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 C

1-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 f

ont panel sequence delay control allows you to set the delay 5 to 2.0 seconds. If set to 2.0 time between activation of each outlet. Its range is from 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 rea

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 es of how you would connect. circuitry (if required). The following diagrams give just 2 exampl

LCD

The LCD display on the front panel indicates current AC line voltage and the total load current that the PS8 PRO is supplying. It also indicates time of day (in 24

hour format) as set by the hour and minute switches. The clock draws power from an internal battery whenever power is not available.

MAXIMUM LOAD

The eight circuit breaker p

otected outlets are rated at 15 amps total, which is equivalent to 1800 watts at 120 volts. If the total load on the PS8 PRO exceeds 15

amps, the circuit breaker on the front panel will trip, cutting off power to all outlets. If this happens, reduce the overall load by unplugging one or more units from

the PS8, then push the circuit breaker button in to reset it.

ADVANCED POWER FILTERING

as specialized internal circuitry to filter out digital and dimmer hash as well as any high frequency noise that is above the audio range.

By using both Common Mode and Differential Mode topologies in series for the filter design we are able to block virtually all of the unwanted noise that is

between the AC line and ground, and also the two sides of the AC line. This has the additional benefit of reducing ground loop problems in your system.

High frequency noise currents in particular are highly attenuated in both directions so that any line noise that could be generated by one of your components is

not allowed to get back into your main AC wiring, so if you use a PS8 PRO in your setup, you can distribute and isolate the noisy components from the sensitive

components in your system. Additionally, any signals above 10kHz ar above 100kHz. e filtered from the line with typically 40dB of attenuation
