Expedition Pro XPL300
5: Insert (sub) connector - This 1/4" connector brings line-level signal in directly before the XPL300 power amplifiers. It is nor-
mally used to return signal from an optional dB1500a or dB1800 subwoofer.
6: Line inputs - Use these 1/4" jacks to connect line-level sources to the XPL300. Channels 1 and 2 are mono 1/4" connectors;
channel 3/4 uses a stereo (TRS) 1/4" connector, with tip carrying left signal and ring carrying right signal. Stereo devices should
always be connected to the stereo channel (channels 3/4). If a wireless receiver is connected to the XPL300 via its internal con-
nectors (see page 14 in this manual), its output arrives at channel 2, which can also carry another line-level source connected
to its line input, as well as signal from a microphone connected to its mic input. If an optional MP3 player is installed, its output
arrives at channels 3/4, which can also carry another two line-level sources (one connected to its line input and a second con-
nected to the CD inputs [see #15 on the following page]), as well as signal from a microphone connected to its mic input.
7: Mic inputs - Use these XLR jacks to connect microphones to the XPL300’s built-in mic preamps. Each channel can carry both
one or more line level sources (see #6 above) as well as a mic source.
8: DSP Effects control - Use this to select one of ten reverb presets (Medium Bright Plate, Best Plate, Medium Dark Plate, Short
Plate, Long Bright Spring, Slapback 2, Slapback w/Verb, Slow St Chor or Best Hall). If you don’t want to hear any reverb, set this
switch to the “Off” position.
9: Mono/Stereo switch - When using one XPL300, set this switch to “Mono” so that the XPL300 power amp receives signal from
both the left and right output sections. When using multiple Expedition Pro speaker enclosures, set this switch to “Stereo”; the
XPL300 will then reproduce only signal from the left output section only (that is, signals panned left at the mixer); the Right out-
put can then be used to send signal from the right output section (that is, signal panned right at the mixer) to a second enclosure.
See the interconnection diagrams on pages 10 - 11 for more information.
10: Outputs - The dual XLR connectors carry line-level output signal from the XPL300. They are used to send signal to a second
XPL300 (or XPL200) being daisy-chained (see the interconnection diagram on the following page) or to an optional DB1500
subwoofer. Note that the signal being output from these connectors is dependent upon the setting of the Mono/Stereo switch
(see #9 above). When set to “Stereo,” the Left XLR connector carries left signal only and the Right XLR connector carries right sig-
nal only; when set to “Mono,” both the Left and Right connectors carry the same monophonic signal, summed from both the left
and right output sections. See the interconnection diagrams on pages 10 - 11 for more information.
11: Main Volume control - This knob determines the final output signal level—you can think of this as being the “master fader.”
Signals from all four channels are routed here just before being routed to the XPL300’s built-in power amplifiers and Left and
Right output jacks (see #10 above).
12: Battery VU meter - If an optional RB 2030 rechargable battery pack is installed, this meter shows how much battery power
remains as it is being charged (Power switch off) or depleted (Power switch on). See #20 on the following page.
13: Output VU meter - This three-segment bar meter shows the continuous output level of the XPL300. For optimum signal-to-
noise ratio, try to adjust all channel and main Volume controls so that program material is usually at or around 0 VU, with occa-
sional but not steady excursions to the red “+3 dB” segment.
14: CD inputs - Connect the outputs of a CD or tape player to this set of dual phono jacks. Signal arriving here returns to stereo
channel 3/4. If an optional MP3 player is installed, note that its output also arrives at channels 3/4, in addition to line-level signal
arriving at its 1/4" TRS line input (see #6 on the preceding page) and signal from a microphone connected to its mic input (see #7
on the preceding page).
15: AC input - Connect the supplied heavy-gauge 3-pin “IEC” power cable here.
16: Voltage selector - Make sure this is set correctly for the country you are in before turning on the power to the XPL300.
17: Gain switch - Sets the line-level TRS input of channel 3/4 (see #6 on the preceding page) to 4 (professional) or -10
(consumer) level.
18: Power switch - Use this to turn power to the XPL300 on or off. If an optional RB 2030 rechargable battery pack is installed, it
will charge when this switch is in the “Off” position.
