3. M ake the connections to the HDL-4. The amplifier/ speaker
connectors on the HDL-4 are removable. If you wish, you
may remove the HDL-4's connectors to facilitate installation
see (Figure 3). Strip 3/ 8" of insulation from the end of each
wire. Tightly twist the end of each wire until there are no
frayed ends. Insert each wire into the appropriate hole on the
spring-loaded connector terminals. Be certain that proper
phasing is observed — connect the positive term inals on the
HDL-4 to the positive terminals on the amplifier and speakers
and the negative term inals on the HDL-4 to the negative ter-
minals on the amplifier and speakers. Re-install the connec-
tors if they were removed. See (Figure 4).
4. Locate the pre-printed Room Labels. Affix the appropriate
label to the recessed area over each ON/ OFF selector button.
