For example if you inserted a {{Model I}} radiator into an {{Classic}} power stand you would notice a (-6dB)difference in acoustical output. Both the {{Model I}} power stand and radiators contain an orange sticker which serve as a easy identifier. If you are purchasing an open box system this is something to keep in mind.

Some of you that have read through the product specifications for the {{Classic}} and {{Model I}} system may have wondered how the systems are able to achieve the same acoustical output given the differences in the power amplifier configuration. We wanted to provide you with further explanation on how this is indeed possible.

The {{Model I}} features one dedicated 250 watt RMS amplifier that powers the {{L1 CR}} and an additional 250 watt RMS amplifier that powers up to two B1 Bass Modules. This brings the total system power handling to 500 watts.

In contrast the {{Classic}} had two 250 watt RMS amplifiers each dedicated to driving one half of the {{L1 CR}} and an additional 250 watt amp that powered up to two B1 Bass Modules. The total system power handling is listed at 750 watts.

Although these numbers serve as a point of reference they do not tell the whole story. During the design of the {{Model I}} the impedance of the L1 Line array was lowered. As a result of the lower impedance, a single 250W amplifier now powers the system to within 1.75 dB of the max SPL of the {{Classic}}. We paid particular attention to this change and conducted many A/B comparisons to confirm that there was no significant audible difference between the two systems. When used in the field with program material, the volume difference between the two systems is unnoticeable.

For those that own both an L1® classic and a model I system it is important that the correct Cylindrical Radiator® loudspeakers are matched to their respective power stands. For example if you inserted a model I radiator into an L1® classic power stand you would notice a (-6dB)difference in acoustical output. Both the L1® model I power stand and radiators contain an orange sticker which serve as a easy identifier. If you are purchasing an open box system this is something to keep in mind.

I hope that you found this information helpful.
