Frequently Asked Questions - SP3.6 MKII Ashly
What is the Ashly SP3.6 MKII?
The Ashly SP3.6 MKII is a stereo 3-way active crossover/signal processor designed for professional audio systems. It provides precise frequency division and level control for three output bands per channel.
How do I set the crossover frequencies?
Use the front panel frequency selectors to choose crossover points. Each band (Low/Mid/High) has independent rotary switches for frequency selection. Refer to the user manual for recommended settings based on your speakers.
Can I use this crossover with powered speakers?
Yes, the SP3.6 MKII outputs line-level signals suitable for connection to powered speakers or external amplifiers. Ensure amplifier inputs match the output levels (+4 dBu nominal).
What is the power requirement?
The unit operates on 100-240 VAC, 50/60 Hz, and includes an internal universal power supply. Check the voltage label on the rear panel before connecting.
How do I connect the SP3.6 MKII?
Connect your audio source to the XLR female inputs (Left and Right). The six XLR male outputs correspond to Low, Mid, and High for each channel. Use balanced cables for best noise rejection.
What does the 'Phase' switch do?
The Phase switch inverts the polarity of that output band by 180 degrees. Use it to correct phase alignment between drivers in multi-way systems.
My unit has a blinking LED. What does it mean?
A blinking or red Clip LED indicates the output signal is near clipping levels. Reduce the input signal or adjust the band level controls to prevent distortion.
Can I mount the SP3.6 MKII in a rack?
Yes, the unit is 1U rack-mountable using the included rack ears. It fits standard 19-inch racks. Ensure proper ventilation around the chassis.
How do I clean the device?
Disconnect power and wipe the exterior with a soft, dry cloth. Do not use water, solvents, or abrasive cleaners. Avoid getting moisture inside the unit.
Where can I find a replacement or repair?
Contact Ashly Audio directly or an authorized service center. The device has no user-serviceable parts. Do not attempt to open the chassis.
