Can I install and control signals on a DCC layout, at any prominent place of my choice on the layout, without detectors or electrofrog turnouts?

Is there a way for my to manually control the signals without having to use detectors?

My name is Conor.  I am 16 years old and I would consider myself a semi-experienced intermediate modeler.

I am in the process of designing and constructing a layout that is 12' x 10' in my basement.  It will have approximately 150 feet of track.

I am new to DCC and understand the basic concepts of the system. (bus line, feeders etc.)

I am planning on using a Digitrax Super Empire Builder 5 Amp Command/Booster Unit and will operate a max of 2-3 trains at a time.
