The Programme 1LT features an internal line-matching
transformer with five power/impedance selections for 100 volt line.
In speaker systems anything over 32
Ω is considered high
impedance. Use of constant-voltage distribution in installation
increases the impedance to the desired level at the speaker
location. With the line impedance well above the nominal speaker
impedance, power loss in long speaker lines is minimised. Smaller
wire can be used without excessive power loss.
The five switchable power tappings are 0.6W,1.25, 2.5, 5.0 and 10
watts accessed through an external connecting block at the rear of
the cabinet.
