Ultra Bass is a Philips patented bass enhancement 

system that uses psycho-acoustics and digital signal 

processing to enhance the bass quality of small 

loudspeakers.  Non-audible low frequency signals are 

replaced by harmonics, making them audible, while 

giving the impression the low frequency signal itself is 

present.

Contrast Plus greatly enhances the degree of black 

to white contrast, thus optimizing the total contrast for 

improved picture clarity.

4 x 3 Expand expands movie images recorded in 

letterbox format by removing the black horizontal bars 

at the top and bottom and filling the entire screen.

16 x 9 Compress compresses full screen movie images 

recorded in letterbox format by adding the black 

horizontal bars at the top and bottom of the TV screen.

Smart Surf eliminates the frustration of trying to 

remember what channels had programs of interest 

while channel surfing.  After establishing the Smart Surf 

configuration with the user-friendly menu, store up to 

ten channels in a Smart Surf ring memory and then 

surf the loop at a touch of a button.

Auto Volume Leveller (AVL) suppresses unexpected 

volume increases in the sound modulation while viewing 

commercials or when switching broadcast channels.

Child Lock is an electronic lock that can be used to 

block channel(s) by entering a unique digit code.  This 

feature is useful in preventing young children from 

accessing undesired program(s).

Close Caption allows the hearing impaired to read 

dialog and narratives (on Closed Caption telecasts) 

without the use of an optional, external decoding 

device.  Program dialog and narrative material are 

printed at the bottom of the screen.  Excellent for 

development of language skills and private viewing 

without disturbing others as well.
