Installation

Unpack and inspect contents. Place on stable surface or mounting stands.

1. Position speakers: Place on stands or isolation pads at ear level.
2. Connect audio sources: Use balanced XLR or TRS cables from audio interface/mixer.
3. Connect power: Plug into AC power outlet.
4. Set initial volume: Start with volume control at minimum position.

WARNING! Speakers are heavy; use proper lifting technique. Ensure stable placement to prevent tipping.

First-Time Setup

Power on speakers; follow setup procedure.

1. Position speakers: Form equilateral triangle with listening position.
2. Connect audio: Use balanced cables to prevent noise.
3. Set volume: Adjust volume control to appropriate level.
4. Configure acoustic controls: Set room EQ based on placement.
5. Test audio: Play reference material to verify operation.

CAUTION! Allow proper ventilation; do not block rear ports.

Controls and Settings

Front panel: Volume control, power indicator. Rear panel: Input sensitivity switch, acoustic controls.

Volume Control: Adjusts output level. Input Sensitivity: +4dBu (pro) / -10dBV (consumer). Acoustic Controls: High shelf (±2dB @ 10kHz), Low shelf (±2dB @ 100Hz), Boundary control (-2dB/0dB/+2dB). Power Switch: Main power on/off.

Connecting Devices

Audio Interface: Balanced XLR or TRS. Mixer: Balanced outputs. Consumer devices: Use -10dBV setting.

1. Turn off all equipment before connecting.
2. Use balanced cables for noise rejection.
3. Match input sensitivity to source device.
4. Connect left and right channels correctly.

Tip: Use high-quality cables and keep cable runs as short as possible.

Operation Guidelines

Optimal performance requires proper setup and break-in period.

1. Break-in period: Allow 24-48 hours of moderate use for optimal performance.
2. Volume levels: Avoid prolonged operation at maximum volume.
3. Positioning: Keep at least 6 inches from walls for proper bass response.
4. Isolation: Use isolation pads or stands to decouple from surfaces.
5. Listening position: Center between speakers at ear level.

WARNING! Do not operate at extreme volumes for extended periods to prevent damage.

Acoustic Controls

Room adaptation controls for optimal performance in different environments.

Control	Function	Settings
High Shelf	Adjusts high frequency response	±2dB @ 10kHz
Low Shelf	Adjusts low frequency response	±2dB @ 100Hz
Boundary	Compensates for placement near boundaries	-2dB/0dB/+2dB

Use these controls to compensate for room acoustics and speaker placement.

Care & Maintenance

Unplug before cleaning. Use soft, dry cloth for cabinet. Use compressed air for drivers.

CAUTION! Do not use liquids or solvents. Keep away from moisture and extreme temperatures.
