Setting the Unit

Setting the Gain properly

• This unit is equipped with a protective function to

prevent malfunction of the unit itself and speakers

from too much output, improper use or improper

connection.

• When outputting sound at high volume etc., this

function will cut off the sound output in a few

seconds. But this is not a malfunction. When you

There is no need to decrease the volume of the head unit and too much output is controlled.

Relationship between the gain of the

amplifier and the output power of the

head unit

turn down the volume of the head unit the sound

output will be restored.

• If sound output is cut, the gain control of this unit

may be improperly set. To ensure continuous

sound output at increased volume of the head unit,

set the gain control of the amplifier to a proper

position according to the preout maximum output

level of the head unit.

•With high output the signal waveform is distorted, if you raise the gain of the amplifier the power changes only slightly.

•If you decrease the volume of the head unit and set the gain control of the amplifier to the proper position but still the sound cuts out from time to time, contact the nearest authorized PIONEER Service Station.
