How to use

Place the monitors at ear level in a nearfield configuration, angled toward the listening position for accurate stereo imaging. Connect the active monitor (powered unit) to AC power and link the passive or secondary monitor as specified by the manufacturer. Select a source via wired inputs (RCA or TRS) or pair a device using Bluetooth 5.0 for wireless playback. Adjust the rotary volume control to set listening level and use the headphone output for private monitoring.

Recommendations

For best monitoring results, allow a short warm-up period after powering on, position the monitors away from reflective surfaces and use them at moderate listening levels to avoid distortion near the low-frequency limit (below 80 Hz). Use balanced TRS connections where possible to reduce interference in studio environments.
