Frequently Asked Questions - iAM-SUM8 Wohler
How do I connect the iAM-SUM8 to my audio interface?
Use balanced XLR or TRS cables from your audio interface outputs to the speakers' balanced inputs. For unbalanced sources, use RCA cables. Ensure the speakers are powered off during connection.
What is the recommended placement for optimal sound?
Place the speakers at ear level, forming an equilateral triangle with your listening position. Keep them at least 20 cm from walls to avoid bass buildup. Avoid obstacles between you and the speakers.
How do I adjust the volume and EQ on the speakers?
Each speaker has a rear panel volume control. EQ adjustments (HF trim, room compensation) are accessed via a small knob or switches; refer to your manual for exact location. Set volume to minimum before powering on.
Why is there hum or noise coming from the speakers?
Hum often results from ground loops. Use balanced connections, keep audio cables away from power cords, and ensure all equipment shares the same power source. If using unbalanced RCA, try a ground loop isolator.
Can I use the iAM-SUM8 with a subwoofer?
Yes, you can integrate a subwoofer. Connect your audio source to the subwoofer's inputs, then route the subwoofer's outputs to the monitors. Alternatively, use a crossover if available. Adjust subwoofer phase and level for seamless integration.
How do I set up the speakers for surround sound?
For surround systems, use multiple iAM-SUM8 units as front, center, and rear channels. Follow your receiver or audio interface's calibration procedure. Ensure all speakers are the same model to maintain tonal consistency.
What is the warranty period for the iAM-SUM8?
Wohler typically offers a 2-year limited warranty on active speakers. Register your product on their website to validate warranty. Keep your receipt as proof of purchase.
How to clean the speaker cabinet?
Unplug the speaker. Wipe the cabinet with a soft, dry cloth. For stubborn dirt, dampen the cloth slightly with water. Do not use solvents or abrasive cleaners. Avoid getting moisture into the port or drivers.
Why is the power LED not turning on?
Check that the power cable is securely connected to both the speaker and a working outlet. Verify the outlet is live. If the fuse inside the speaker has blown, replace it with the same rating (see manual). If the problem persists, contact support.
Can I mount the speaker on a stand or wall bracket?
Yes, the iAM-SUM8 has threaded inserts on the bottom and rear for optional mounting brackets (not included). Use a stand rated for the speaker's weight. Ensure the surface is stable and secure to prevent tipping.
