EQ Cards

The B1500 and B2000 power amplifiers are compatible with the entire range of

BOSE Equalisation Cards.

When configuring a bi-amplified system jumper links allow you to select high pass

filter functionality on certain EQ cards for mid/high loudspeakers. This rolls off the

low frequency to the mid/high loudspeaker providing the low frequency crossover

point to match BOSE bass loudspeakers. An example of this would be BOSE 502

Articulated Array on channel A with the HPF link in place and a BOSE 502

B Bass

Module on channel B with no HPF link. Note: When using the BOSE series II-S EQ

cards the HPF selection is made on the EQ card and not on the amplifier board.

In order to fit the EQ Cards you must remove the unit s cover (ENSURE THAT

ELECTRICAL POWER TO THE UNIT IS DISCONNECTED BEFORE

REMOVING THE LID AND FITTING THE EQ CARDS).

For Both B1500 & B2000

Using a TORX T10 screwdriver (not supplied) remove the 12 TORX T10 screws that

retains the cover. Remove the cover.

Locate the EQ Card sockets. Insert the EQ Card into the socket, noting the orientation

of the mating connector.

Remove the bypass jumper link for the channel, (A = J7 or B = J6)

If you want to activate the high-pass filter function of the EQ Card, you should fit the

jumper that you previously removed from (J7 or J6), to the HPF pins for the channel

(A = J8 or B = J5) linking pins 2 and 3. Note: When using the BOSE series II-S EQ

cards the HPF selection is made on the EQ card and not on the amplifier board.
