British Manufacturer has seen excellent reviews for their AE1 monitor. Speaker features electronic crossovers and dedicated amplification (50 watts class A/B) to each driver. On/Off switch is on the amp plate just below the power plug there is a small LED on the front panel to remind your that the amp is on but is not obtrusive and is a faint reminder. Driver cone material is metal similar to the cones featured in the AE 300 series lineup Inputs are limited to two 1 x XLR and 1xRCA. Amplifier has bass and treble +/- 2db trim pots plus volume control. Sound is magnificent and dynamic as monitors should be. You are correct this setup does not feature a 3.5 jack , bluetooth or wireless connectivity it's not one of those.
