5. Setup

Follow these steps to set up your Pyle PCO875 Power Sequence Controller:

5.1 Rack Mounting

The PCO875 is designed for standard 1U rack mounting. Ensure you have adequate space in your equipment rack. Use appropriate rack screws (not included) to secure the unit firmly to the rack rails.

5.2 Connecting Devices

Connect your audio, video, or other electronic equipment to the outlets on the rear panel of the PCO875. These are the sequenced outlets (CH1-CH8). The order in which you connect devices to these outlets will determine their power-up and power-down sequence. For example, connect amplifiers or power-hungry devices to later channels (e.g., CH8) and source devices (e.g., preamps, mixers) to earlier channels (e.g., CH1).

The two outlets on the front panel are 'always-on' outlets. Use these for devices that require continuous power, such as external hard drives, charging devices, or equipment that does not benefit from sequencing.

5.3 Power Connection

Connect the main power cable of the PCO875 to a suitable grounded AC power outlet. Ensure the power switch on the front panel is in the 'OFF' position before connecting to the main power supply.

6. Operating Instructions

Operating the Pyle PCO875 is straightforward:

6.1 Powering On

To power on the unit and initiate the power sequence, simply press the main POWER switch located on the front panel. The unit will begin its 1-second sequential turn-on process for channels 1 through 8. The corresponding LED indicators (1-8) will illuminate as each channel powers on.

6.2 Powering Off

To power off the unit and initiate the power-down sequence, press the main POWER switch again. The unit will perform a reverse 1-second sequential turn-off process, starting from channel 8 down to channel 1. The LED indicators will extinguish as each channel powers off.

6.3 LCD Display

The front-panel LCD display provides a real-time readout of the incoming AC voltage. This allows you to monitor the power conditions and ensure your equipment is receiving stable voltage.

6.4 USB Charging Port

The 5V USB port on the front panel can be used to charge compatible external devices such as smartphones or tablets. This port is always active, regardless of the main power switch position.
