The DYNACORD PowerSub 112 and 212 powered subwoofers are perfectly suited for building multi-component active loudspeaker systems, e. Due to its vented design this subwoofers offers much more musical, tight and punchy bass than typical bandpass designs often found in this type of product range. PowerSub 112 The PowerSub 112 is great for enhancing the low frequency response of active fullrange speakers like the D 8A. 3 MAINS CONNECTOR (MAINS IN) The PowerSub receives its power supply via the lockable MAINS IN connector. Connect the PowerSub only to a mains network, which corresponds to the requirements indicated on the type plate. 4 LIMIT INDICATOR (LIMIT) Brief blinking of the LIMIT LED indicates that the power amplifier of the PowerSub is operated at its limits. 7 POLARITY SWITCH (PHASE) Select 0° (button not pressed) if the signal polarity should not be inverted. The level of the output signal is independent of the setting of the level control VOLUME ("Pre Fader"). Whenever possible, balanced signal feed is always preferable to guard against potential noise or HF-interference. CAUTION: Before making any connections or disconnections, make sure to set the level control VOLUME to the counterclockwise stop. The level of the output signal is independent of the setting of the level control VOLUME ("Pre Fader"). 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 and use the master faders 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. [. . . ] Slowly raise channel fader and master faders on the mixing console to the desired positions ­ i. If the reproduced sound asks for extreme accentuation or lowering of the bass level, adjust the VOLUME setting on the PowerSub 212. Individual sound adjustments necessary can be made using the controls of the mixer's corresponding input channels. After use, first switch off the D 8A, then the PowerSub and then the mixing console, so that distracting power-off noise will not occur. [. . . ]
