Connection and Installation

Input Connections

Before making connections to the PA-30 signal inputs, find the nominal output level of your signal source (this information is usually given in the Specifications section of the instruction manual). Equipment operating at –10 dBV should be connected to the RCA (phono) inputs, while +4 dBm equipment will operate best if connected to the XLR-type inputs. (Low-level signal such as an electric guitar or phonograph cartridge will require an external preamplifier.)

From Source Equipment

Components that operate at –10 dBV normally feature either RCA or 1/4-inch phone output connectors, presenting an unbalanced (two-connection) drive. Standard connecting cables and adapters may be used with such equipment. If you are making your own cables, refer to Figure 5 for wiring details.

Professional +4 dBm components, on the other hand, may feature either 1/4-inch phone or XLR-type output connectors, presenting either an unbalanced or a balanced drive. In some cases, standard microphone cables may be used for such equipment; in others, special cables or adapters may be required.

Figure 6 shows the recommended wiring configu- rations for a few standard +4 dBm output types. Refer

to this figure when determining the types of cables and adapters to use in connecting to the PA-30 XLR inputs. Take care to observe the polarity conventions indicated; input polarity reversals may cause acoustical phase cancellation, resulting in unnatural sound.
