HD audio (headphone jack/microphone jack)

Find the "Front panel audio headers/pin connectors" on the motherboard. Plug in the wires according to the motherboard manual.

USB 2.0

Find the "USB 2.0 Headers/pin connectors" on the motherboard. Plug in the wires according to the motherboard manual.

Find the "USB 3.0 Headers/pin connectors" on the motherboard. Plug in the wires according to the motherboard manual.

Power switch, Power LED, HDD LED, Reset switch

These wires plug into the motherboard where all the front panel switch/pin connectors functions are located. The motherboard manual will have a description of where to plug these in, usually their location is labeled in the motherboard manual.

PCB PANEL / PORTS

DARK BASE PRO 900

1. 4-Pin PWM Connector to M/B
2. 4-Pin PWM Connector
3. 3-Pin Fan Connector
4. LED Strip Connector
5. Power Connector (SATA)
6. Fan Speed Controller Switch Connector
7. QI Charger Power Connector

DARK BASE 900

1. 4-Pin PWM Connector
2. 3-Pin Fan Connector
3. Fan Speed Controller Switch Connector
4. Power Connector (SATA)

FAN CONTROLLER

The fan controller has two modes of operation.

1. Automatic operation
   For this the PWM signal of the MB is used and the speed of all fans connected (PWM and 3-pin) can be adjusted automatically through the MB. In this mode the fan controller slider switch must be set to the first position "0" on the far left.
2. Manual control
   When the fan controller slider switch is moved from its first position "0" to the right, the PWM signal is dropped and the fan speed can be regulated manually.

If the slider switch is subsequently reset to its first position "0", the PWM signal regains automatic control of the fans.

Automatic PWM control of the fans requires cable "A" of the PCB panel is connected to a PWM connector on your MB. Lacking such a connection the speed of the fans connected can only be regulated manually.

DARK BASE 900
Dark Base 900 does not have automatic regulation. The speed of all fans (PWM and 3-pin) connected to the PCB panel are manually regulated using the slider switch.

LED INSTALLATION AND USE (ONLY PRO-VERSION)

The LED illumination supplied can be freely positioned and installed in the case according to system configuration using the attached adhesive strips. To power them the lamps must be connected to socket "D" on the PCB panel. Using switch "I" and switches the lamps on and off and permits the illumination color to be selected (red, green, blue, white, orange).

QI Charger use (only Pro-Version)

The preinstalled Qi charger supplied with Dark Base Pro 900 allows cable-free charging of all external devices that are compatible with the Qi standard. If the device (e.g. smartphone) is equipped with such a feature it can be charged without cable connection by placing it on the plate marked "J" on the Dark Base Pro 900.

An acoustic signal will indicate that charging has started upon laying the device on the charger.

In so doing please ensure you position the device carefully on the center of the charging plate "J". The charging coil of the Dark Base Pro 900 charging device is located in the middle of charging plate.
