Input Terminal Connections
NOTE:
The loudspeaker terminals should be tightened as firmly as
possible by hand. Do not use pliers or any other tools as
this may damage the terminals.
The provision of separate inputs for the low frequency and high frequency sections of the crossover
allows the PQS-402 to be operated in 3 modes:
Single wire connection
Bi-wire connection
Bi-amp connection
Single Wire Connection
This is the most commonly used method of connecting a loudspeaker and power amplifier. Only one
loudspeaker cable is used for each loudspeaker. The PQS-402 will be shipped configured for this
mode of operation. In this case the red terminals on the DDD and woofer inputs will be connected
together and the black terminals on the DDD and Woofer inputs will be connected together. These
connections must be made using the special links provided. The loudspeaker cable should be
connected to the woofer input terminals.
An amplifier capable of delivering at least 340W rms into 4 ohms per channel should be used for each
speaker.
Bi- Wire Connection
In this method of connection the woofer and DDD inputs are connected to the power amplifier with
separate loudspeaker cables. Ensure that the links fitted between the woofer and DDD input terminals
have been removed.
An amplifier capable of delivering at least 340W rms into 4 ohms per channel should be used for each
speaker.
Bi- Amp Connection
In this method of connection the woofer and DDD inputs are driven by separate power amplifiers.
Ensure that the links fitted between the woofer and DDD input terminals have been removed.
An amplifier capable of delivering at least 200W rms into 4 ohms per channel should be used for the
woofer input and one capable of delivering at least 140W rms into 4 ohms per channel should be used
for the DDD input.
We recommend that you use loudspeaker cables terminated with high quality spade lugs, as these
provide the best electrical connection. The lugs should be either soldered or crimped to the speaker
cable – the latter is preferred. We do not recommend the use of bare wire to connect to the speaker
terminal. This produces an inferior connection that will further degrade as the bare conductors become
tarnished.
5. LOUDSPEAKER BREAK IN
Like all audiophile equipment, German Physiks loudspeakers require a break in period from new
before they reach their optimum level of performance. The music used for the break in should be
dynamic in order to properly exercise all the components of the loudspeaker.
For the first 10 hours play the loudspeaker at low level only. This is a level where you would easily be
able to carry out a conversation without needing to raise your voice.
