Frequently Asked Questions - Fusion HF Compressor Solid State Logic
What is the Fusion HF Compressor used for?
The Fusion HF Compressor is designed to tame high-frequency harshness and add warmth to your mix. It applies compression specifically to the treble range, helping to smooth out sibilance and brittle top end while preserving dynamics.
How do I connect the Fusion HF Compressor to my setup?
Use balanced XLR or TRS cables. Connect your audio source to the Input jacks and route the Output to your next processor or audio interface. Ensure the unit is powered off before making connections.
What are the typical settings for vocals?
For vocals, start with a Threshold around -10 dB, Ratio of 2:1, fast Attack (0.1 ms) and medium Release (50 ms). Adjust Makeup Gain to match bypassed level. Fine-tune based on the source material.
Can I use this compressor on a stereo bus?
Yes, the Fusion HF Compressor is a stereo unit with linked channels. It is excellent for mastering or mix bus processing, adding air and presence while controlling harshness across the stereo image.
How do I clean and maintain the unit?
Disconnect power. Use a soft, dry cloth to wipe the front panel and chassis. Avoid liquids and abrasive cleaners. Keep ventilation slots free of dust. For internal cleaning, contact authorized service.
What does the sidechain filter do?
The sidechain filter allows you to focus compression on specific frequencies. When engaged, it lets you filter out low frequencies from the sidechain, so the compressor reacts less to bass content, making the high-frequency compression more even.
Is this unit compatible with 19-inch racks?
Yes, the Fusion HF Compressor is designed for standard 19-inch racks and occupies 1U of space. Use included rack ears for secure mounting.
What power supply does it require?
The unit has an internal universal power supply that accepts 100-240 V AC, 50/60 Hz. It automatically adapts to your local mains voltage.
How do I know if the compressor is working correctly?
Watch the Gain Reduction LEDs: they indicate how much compression is applied. When the threshold is exceeded, the LEDs light up. Compare bypassed and compressed signals to hear the effect.
What should I do if the unit stops working?
First, check power connections and cables. Ensure the unit is receiving power (LED on front). If still not working, do not open the chassis. Contact Solid State Logic support or an authorized service center.
