hi josephat

The answer is 'yes'.
The SLX systems are available in five 24 MHz wide frequency ranges:
G4 (470-494 MHz)
G5 (494-518 MHz)
H5 (518-542 MHz)
J3 (572-596 MHz)
L4 (638-662 MHz).
Within these bands, there is the ability to operate up to 12 total systems. If all 5 bands are utilized, then about 25 systems can usually be operated together.

Available bands for the  MX890 are as follows:
G4   (470.12 493.82 MHz)
G5   (494.12 517.75 MHz)
H5   (518.2 541.8 MHz)
J3   (572.2 595.8 MHz)
L4   (638.2 661.8 MHz)

My forte is audio.. Car/Home/Boat. You name it, I will help you even if it is just a link to more assistance. If you want to interface new gear to your factory radio I can do us both a favor and tell you to go to or call them at 1.800.555.7088. They really are top notch at doing that for people with great support. I will re-direct most questions of that nature to them. The rest of it... I am eager to help you with. I am also not a 'Master Installation Technician' that will tell you I cannot assist you with cars not made in the USA. Talk to me about any audio upgrades including 'bang for the buck'.
Specialties include: Overall Acoustics, Gain structure/settings and Enclosure design, system design/consultation, when/where to get which upgrades as well as other pertinent info for the mobile audio enthusiast and much more.
I also am NOT interested in buying your used gear so do not waste our time asking me.


My specialty as it is offered here, is Mobile and Home Audio Consultation.

My mother was a record producer so I picked up a lot of additional professional knowledge and experience through the years. I was a Drum Tech for the Banshee reunion tour and toured as sound man with a regional act called Champion so I have practical knowledge for many aspects of audio.

If I cannot directly answer your question I will use my vast resource network to help you get a usable answer.
