db Drive E5 HLC6 6-Channel Line Output Converter User Manual

Introduction

This manual provides detailed instructions for the installation, operation, and maintenance of your db Drive E5 HLC6 6-Channel Line Output Converter. The E5 HLC6 is designed to convert high-level speaker signals from your car audio system into low-level RCA signals, allowing you to connect aftermarket amplifiers to factory head units without RCA outputs. It features 6 channels, a recommended fuse rating of 1 Amp, a remote trigger output, an output level of 9.5 Volts, a frequency response of 10Hz - 25kHz, THD of 0.01%, and an input impedance of 180 Ohms.

Safety Information

Please read all instructions carefully before installation and operation. Failure to follow these guidelines may result in damage to the unit, your vehicle, or personal injury. Always disconnect the vehicle's battery before performing any electrical work. Ensure all wiring is properly insulated and secured to prevent short circuits. Consult a professional car audio installer if you are unsure about any part of the installation process.

• Do not expose the unit to moisture or extreme temperatures.
• Ensure proper ventilation around the unit.
• Use only the recommended fuse rating (1 Amp).
• Keep out of reach of children.

Product Overview and Controls

Figure 1: Top view of the db Drive E5 HLC6 Line Output Converter.

The image displays the top panel of the db Drive E5 HLC6 Line Output Converter. Key features visible include the 'db DRIVE' logo, 'OKUR ES HLC6' model designation, and '6 Channel Line Output Converter' text. The panel features three rotary knobs labeled 'SUB OUTPUT VOLUME', 'REAR OUTPUT VOLUME', and 'FRONT OUTPUT VOLUME' for adjusting the output levels of each channel. There are also toggle switches for 'SUB' (150/SHORT), 'SUB' (SUMMED/SEPARATE), and 'REAR' (SUMMED/SEPARATE) settings, which control signal processing and output configuration. Output terminals for SUB, REAR, and FRONT are indicated, along with screw terminals for input connections at the bottom of the unit.

Control Descriptions:

• SUB OUTPUT VOLUME: Adjusts the output level for the subwoofer channel.
• REAR OUTPUT VOLUME: Adjusts the output level for the rear channels.
• FRONT OUTPUT VOLUME: Adjusts the output level for the front channels.
• SUB (150/SHORT) Switch: Likely controls a low-pass filter or impedance setting for the subwoofer channel. "150" might refer to a 150Hz filter, "SHORT" for a full-range or bypass.
• SUB (SUMMED/SEPARATE) Switch: Determines if the subwoofer output signal is a sum of all input channels or derived from specific input channels.
• REAR (SUMMED/SEPARATE) Switch: Determines if the rear output signal is a sum of all input channels or derived from specific input channels.
• Input Terminals: Screw terminals for connecting high-level speaker wires from the factory head unit.
• Output RCA Jacks: RCA outputs for connecting to aftermarket amplifiers.
• Remote Trigger Output: Provides a 12V turn-on signal for connected amplifiers.

Setup and Installation

Proper installation is crucial for optimal performance. It is recommended to have this unit installed by a qualified professional.

Wiring Connections:

1. Power Connection: Connect the +12V terminal of the HLC6 to a constant +12V power source from the vehicle's battery, fused at 1 Amp.
2. Ground Connection: Connect the GND terminal to a solid chassis ground point in the vehicle. Ensure a clean, bare metal connection.
3. Remote Input (Optional): If your factory head unit has a remote turn-on output, connect it to the HLC6's remote input. Otherwise, the HLC6 can generate a remote output signal from the audio input.
4. High-Level Input: Connect the speaker wires from your factory head unit or amplifier to the corresponding high-level input terminals on the HLC6. Ensure correct polarity (+/-) for each channel (Front Left, Front Right, Rear Left, Rear Right, Subwoofer Left, Subwoofer Right).
5. RCA Output: Connect RCA cables from the HLC6's output jacks (SUB, REAR, FRONT) to the input RCA jacks of your aftermarket amplifiers.
6. Remote Output: Connect the HLC6's remote trigger output to the remote turn-on input of your aftermarket amplifiers.

Mounting:

Mount the HLC6 in a secure, dry location away from direct heat and moisture. Ensure adequate ventilation around the unit. Use screws or other appropriate fasteners to secure the unit to a stable surface.

Operating Instructions

Once installed, the E5 HLC6 requires minimal operation. The primary adjustments are the output level controls and the signal summing switches.

Adjusting Output Levels:

• Turn the volume of your factory head unit to about 75% of its maximum.
• Slowly increase the SUB, REAR, and FRONT OUTPUT VOLUME knobs on the HLC6 until you achieve the desired output level without distortion.
• Fine-tune the amplifier gain settings after setting the HLC6 output levels.

Using Summing Switches:

• SUMMED: Use this setting if your factory system has separate high-level outputs for different frequency ranges (e.g., separate tweeter and mid-range outputs). The HLC6 will sum these signals to create a full-range output.
• SEPARATE: Use this setting if your factory system provides full-range signals to each speaker output. The HLC6 will process each channel independently.
• Experiment with the "150/SHORT" switch for the subwoofer channel to determine the best sound for your setup. "150" likely engages a low-pass filter at 150Hz, while "SHORT" might bypass it or provide a full-range signal.

Maintenance

The db Drive E5 HLC6 is designed for reliable operation and requires minimal maintenance.

• Keep the unit clean and free of dust. Use a soft, dry cloth for cleaning.
• Do not use harsh chemicals or abrasive cleaners.
• Periodically check all wiring connections to ensure they are secure and free from corrosion.
• Ensure the fuse is correctly rated and in good condition. Replace only with a 1 Amp fuse if necessary.
