Amplifying Your DP/4+ Through a Home Stereo System
If you are thinking about amplifying your DP/4+ through your home stereo, please be careful. A
home stereo is great for playing CDs, albums or tapes — the dynamic range of these media is
limited, and your speakers aren’t usually subjected to extreme volume changes and frequency
transients. While the dynamic range of CDs is significantly greater than LPs or tapes, the output
of a CD player is still conservative compared to output of a pro-level effects processor. Running
your DP/4+ (or any pro-level product) through a home stereo at high volume levels can damage
your stereo system and/or speakers. If your only means of amplification is your home stereo, set
the Level (dBu) switch to the -10 dBV position, set the Output Knobs to around the 12 o’clock
position, and try to keep your levels on the conservative side.
Powering Up Your DP/4+ In a MIDI Configuration
Just as you would power up the individual components before turning on the amplifier in your
home stereo system, you should first turn on the MIDI data transmitting source (processors,
keyboards, modules, etc.) before you power up the receiving MIDI source. For instance, if you’re
using the DP/4+ to receive MIDI information from a keyboard/sequencer, you would turn the
keyboard on before the DP/4+. This will prevent any unwanted MIDI information from being
“spit” out of the transmitting source (keyboard/sequencer) during power up, which could
confuse the MIDI receivers, thereby disabling them. If this should occur, turn off the receiving
module, and then turn it back on.
