EQUALIZATION CARDS
The Boulder 2008 Phono Preamplifier uses one of three equalization
curves selected by the front panel pushbuttons labeled RIAA, EQ1, and
EQ2. The 2008 is shipped with the RIAA as standard. Optional equal-
izations may be purchased and installed by your Boulder dealer. These
are PC cards which are installed into the EQ1 and EQ2 positions.
If no card has been installed, the EQ1 or EQ2 pushbuttons will not
function.
The following pages show the five equalization curves, including
the standard RIAA, available from Boulder as an option. All graphs are
referenced to 0 dB at 1 kHz. For other curves, consult your Boulder
dealer.
