Peavey DPE 2P, Руководство по эксплуатации, Страница: 8 / 16

WHEN USING STANDS OR POLES, BE SURE TO FOLLOW THESE PRECAUTIONS:
Check the stand or pole specs to make sure that it can support the weight of the DPE
™
2P (DPE 2P 67 lbs./30.5 kg), and observe all
safety precautions stated by the stand manufacturer, including the maximum height for which the stand is rated.
Always place the stand on a flat, level and stable surface, and be sure to fully extend the stand legs as per the stand
manufacturer’s instructions.
Orient the stand legs for the least danger of tripping to those in the vicinity of the stand. Never block a doorway or hallway
with the legs of a stand.
Route cables so that people will not trip over them or tip the speaker over. Use of duct tape, cable channels or guards, or other
appropriate tie-down/cover-up devices should be carefully considered and implemented.
When installing or un-installing the speaker on the stand, it is a good practice to have a helper if possible, as it can be hard to
“thread the needle” and mate the stand cup to the stand pole while holding the DPE 2P speaker system at arm’s length. It is also
helpful if someone holds the speaker stand and pole down while the DPE 2P is removed from the stand pole; this prevents the
DPE 2P from pulling the pole up with it.
When using stands outdoors, never attach banners or flags to the stands or the DPE 2P speaker system, as strong winds may
cause the speaker to blow over. If there is a possibility of windy conditions, it may be prudent to consider weighting or locking
down the stand legs to prevent the DPE 2P speaker system from being blown over.
CONNECTING A SIGNAL TO THE DPE 2P-4P
There are a variety of ways to input a signal to the DPE 2P-4P. The two inputs (8,9) provide either a balanced mic- or line-level
input, allowing the use of a 1/4" TRS (ring-tip-sleeve) type phone plug OR a male XLR plug.
Unbalanced inputs are also provided, as the 1/4" input (8,9) can take a standard single-ended (tip-sleeve) phone plug.
Alternatively, the RCA phono jacks (10) of input 2 can be used. The RCA jacks do not provide a Left and Right stereo input,
as the DPE 2P-4P is a monophonic sound source. Instead, the two jacks mix and buffer any two RCA sourced signals and send
them on to the Gain control of input 2 (1 3).
Do not connect cables to the jacks while the unit is ON with the Gain knob(s) turned up! While a standard single-ended 1/4”
phone plug-equipped cable will work well and the balanced input circuitry of the inputs (8,9) will provide some interference
rejection, a balanced cable using either the balanced TRS 1/4” phone plug or the XLR plug will provide superior interference
rejection and performance.
Sometimes, with difficult interference problems, it will be helpful to lift the shield ground on a balanced cable at the DPE 2P-4P
end by only using the ground lift switch (5). Check any input changes carefully, always turning the gain control down before
plugging and unplugging cables or engaging the ground lift switch.
Use of high quality, premium cables is recommended for the DPE 2P-4P, as these usually have better shielding and materials
and will provide greater long-term reliability. The best option is a shielded, balanced XLR cable no longer than necessary to
reach the DPE 2P-4P. It is usually a good idea to leave some slack at the input to the DPE 2P-4P and also to tape the cables
down or run them under a cable guard to avoid anyone tripping over them or pulling the DPE 2P-4P over when stand
mounted.
GAIN CONTROL ADJUSTMENT
The DPE 2P-4P is equipped with a Gain control (13) on each of the two input channels to facilitate use in many different
applications. With the Gain control adjusted fully clockwise, gain is at maximum and the input sensitivity is 0.200 V RMS for
full-rated output. When driving the DPE 2P-4P from a mixer, it may be advantageous to reduce the input sensitivity by turning
the Gain control to the halfway point. The DPE 2P-4P will now more closely match a typical power amp.
If the mixing board indicates clipping of its output signals, then all of the DPE 2P-4P power capability is not being utilized
cleanly. Clipping the signal before it gets to the DPE 2P-4P is not optimal. Reduce the mixer output level and turn up the Gain
control(s) on the DPE 2P-4P.
The amplifiers in the DPE 2P-4P are equipped with DDT
™
and multiple LED indicators to show that DDT has engaged (15,16,
front grille logo).
If the sound seems heavily compressed, check these indicators; if it is blinking RED more than occasionally, then the drive level
from the mixer (or the Gain control/s {13} on the DPE 2P-4P) needs to be reduced.
When first turning on the sound system, switch on all upstream electronics first, then the DPE
