Performance Limits - McIntosh MAC 4200 Owner's Manual

PERFORMANCE GUARANTEE
Performance Limits are the maximum deviation from
perfection permitted for a Mclntosh instrument. We pro-
mise you that when you purchase a new MAC 4200 from
a Mclntosh franchised dealer, it will be capable of or can
be made capable of performance at or exceeding these
limits or you can return the unit and get your money
back. Mclntosh is the only manufacturer that makes this
statement.
PERFORMANCE

Trade Commission Regulation concerning power output
claims for amplifiers used in home entertainment products.
