Tascam PA-30 - Manual (Page 6)

6. INPUTS (A & B, XLR & RCA Type)
Two input connectors are provided for each channel:
one RCA (phono) jack and one XLR-type female
connector. Either connector may be used on a given
channel, but both connectors for a single channel
should not be used simultaneously.
Both inputs present a high impedance, and cause no
appreciable loading to source outputs. Input sensitivity
is –10 dBV (0.3 volt RMS) at the RCA inputs, and +1.3
dBu (0.9 volt RMS) at the XLR inputs, for rated output
(with Input Level control at maximum). Pin
assignments are as follows:
XLR-type RCA-type
Pin I = common Shell= common
Pin 2= 'high'(+) Tip = 'high'(+)
Pin 3= 'Iow'(–)
Virtually any line-level source may be connected to
these inputs. (Refer to the 'Connection and Installation'
section for further details.)
7. MODE switch
A single two-position slide switch (on rear panel)
selects either monophonic BTL (Balanced
Transformerless, also known as 'bridged', with switch
set to BTL) or stereo operation (with switch set to
STEREO).
If the MODE switch is not correctly set, damage to the
loudspeakers or to the PA-30 may result. For a
complete explanation of use of the MODE switch,
consult the section on 'BTL Operation' on page 9 of
this manual.
8. SPEAKERS (A & B)
A pair of color-coded locking terminals is provided for
output connections to each channel of the PA-30. They
will accommodate stripped bare wire, or tinned wine
ends. The minimum allowable load impedance for each
output is 8 ohms.
The actual output connection configuration will vary
depending upon the mode of operation selected and
the number and type of loudspeakers used. Please
refer to the sections on 'BTL Operation' and 'Output
Connections' before making connections to the PA-30
outputs.
9. Mains Power Cord
The inlet for AC power to the PA-30 is a two-prong
ungrounded plug (rear panel mounted). The PA-30
requires 120/230 volts AC at 50/60 Hz. It draws 8 watts
at idle, and 130 watts at full rated output.
