decrease the volume, little by little
Poco a poco means gradually.
The literal translation of "Poco a poco" is "Little by little". The expression is used to prompt someone to be patient and conscious of his/her limitations when pursuing some ambitious goal.
"extenders" is not a Spanish word, but the rest means: "Little by little the extenders"
