Caution:
After installing the system, first switch on the mixing console and
position the mixer's master faders to their minimum settings. That followed,
switch on the PowerSub 312 and use the SUB LEVEL to adjust the desired
volume setting. Otherwise, high sound levels caused by unintentional
playback of a program source could be the result, which might cause
hearing damage.
This Quick Start Manual outlines setup and operation of the PowerSub 312 being used as subwoofer
satellite system connected to a DYNACORD CMS 1000 or CMS 1600 mixer.
1.
Place your satellite speakers, e.g. DYNACORD D 8, mounted on pole-mount stands to the left
and to the right. The lower edges of the speaker systems should be approximately 1m above
the audience to provide sufficient coverage and to prevent that listeners nearby are subject to
extreme sound levels.
2.
Place the PowerSub 312 in the area between the satellite speaker systems and, using suitable
SPEAKON speaker cables, connect the satellites to 'LEFT SATELLITE SPEAKER OUTPUT'
and 'RIGHT SATELLITE SPEAKER OUTPUT' on the rear panel of the PowerSub 312.
3.
Using suitable XLR-type cables connect the Master Outputs of your mixing console, e.g.
DYNACORD CMS 1000, to 'LEFT INPUT' and 'RIGHT INPUT' of the PowerSub 312. Position
the master faders on the mixer to their minimum setting. Now, switch on the mixer.
4.
Connect the PowerSub 312 to the mains outlet using the supplied PowerCon mains cord. Plug
the blue PowerCon connector into the blue 'Mains In' socket. A twist locks it in place. Use the
red 'Power On' switch to power-up the PowerSub 312.
5.
Connect a microphone to input channel '1' of the mixer, e.g. CMS 1000. Set all rotary controls
to their center position. While speaking or singing loud into the microphone adjust the channel's
'Gain' control so that the green 'SIGnal' LED lights. The red 'PeaK' LED should not light at all or
blink only once in a while. The red LED indicates that the audio signal is already distorted within
the input channel. This will not cause any damage. However, the sound will suffer from spurious
distortion.
6.
Slowly raise channel fader and master faders on the mixing console to the desired positions
– i.e. volume settings.
7.
Now you can balance the sound between the bass and mid-high range using the 'SUB
LEVEL' control on the PowerSub 312. Using a CD-Player is also an effective way to adjust
the sound balance. A CD-Player of course has to be connected to the 'LINE' inputs or via the
'2TRACKRET' RCA-type sockets on the CMS 1000 mixer.
8.
Your system is now ready for operation. Individual sound adjustments necessary can be
made using the controls of the mixer's corresponding input channels. If the reproduced sound
asks for extreme accentuation or lowering of the bass level, adjust the 'Sub Level' setting on
the PowerSub 312. Input channel sound controls of the mixing console should be reserved
for moderate settings. Extreme settings indicate that the PowerSub 312's 'SUB LEVEL' is
incorrectly adjusted.
9.
Now, have fun with your PowerSub 312 satellite system!
10.
After use, first switch off the PowerSub 312 and then the mixing console, so that distracting
power-off noise will not occur. When using a DYNACORD CMS mixer, no power-off noise will
be output from the 'Master Outputs'. This allows switching off the mixer first without a problem.
