Q: How many channels of the modulator?  I need order 2-3 unit for our hotel , Could you provide for us?

A: Yes, We would like provide every customer requirys .

Q:How about the quality?

A: We use the Modulator IC quality arrive the Top of CATV Level. And its built-in 16way combiner.

Use our 16channels modulator needn't install combiner for Lonely.

Q: Why your delivery time is 5-7 work days? So late,

A: Sorry for this 5-7 work days, Because of the adjacent modulator is a high technonus, and clearly tenology products,

Every frequency all is number, and the every channels all very closel, Always must clearly and clearly for it.

So the delivery time need a little delay, The another is, for 1-2 unit order, and for 100 units and more than 100 unit modulator,

Our delivery time also is same as 5-7 work days.

Q: How about your warranty?

A: Our warranty is 12 months, If in warrant time have problem, we also send spare parts for your replace it,

In mass order, we provide 1% spare part for you solve small problem.
