4. CONNECTING YOUR LOUDSPEAKERS
The German Physiks PQS-402 is a 2 way loudspeaker with separate input terminals for the low
frequency and high frequency sections of the crossover. These drive the woofers and DDD drivers
respectively and are labeled as such. Provision is also made to allow the output level of the low
frequency and high frequency cross overs to be adjusted.
The input terminals and cross over adjustment points are located on a panel fitted on the back of the
lower woofer cabinet. Figure 9 identifies the features on this panel.
