Tascam PA-30 - Manual (Page 7)

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.) 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.
