⁄
" TRS output connector provides access to an equalized line level output signal for each
4
channel. If equalizer cards are installed, this signal has passed through the internal equal-
izer, but has not passed through the amplifier itself. (For additional information on EQ cards,
see Input Modules on page 10.)
This is helpful if several devices are going to be driving similar Bose
loudspeakers, for example) with the same source signal. With EQ cards installed in the
Model 2060 or Model 2150 amplifier, the EQ OUT (output) of the amplifier can be connected
to the line level inputs of additional devices driving the same type of Bose loudspeakers
(e.g. 402 loudspeakers). Be sure to use EQ cards that correspond to the type of loudspeak-
ers.
4. Equalizer present LEDs
When you install an equalizer card, the corresponding LED illuminates to indicate the
presence of the card.
Each channel can utilize a different card. For example, the Bose Model 2150 commercial
power amplifier can have both a 402
a 502B card in either card position, it automatically selects the high frequency output of the
other card. When a system uses two or more amplifiers, and you are using a 502B module,
use the EQ BI-AMP/FULL RANGE switch to run in the bi-amp mode.
Note: When EQ cards are installed, the input module recognizes the cards and switches to
the equalizer circuitry. If no cards are installed, the input module bypasses the equalizer
circuitry and no LED will illuminate.
