User manual DYNACORD VECTOR

[. . . ] Servicing is required when the apparatus has been damaged in any way, such as powersupply cord or plug is damaged, liquid has been spilled or orbjects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped. Do not expose this equipment to dripping or splashing and ensure that no objects filled with liquids, such as vases, are placed on the equipment. To completely disconnect this equipment from the AC Mains, disconnect the power supply cord plug from the AC receptacle. The mains plug of the power supply cord shall remain readily operable. [. . . ] Due to line current harmonics, we recommend that you contact your supply authority before connection. With buying a DYNACORD PowerSub 312 you have decided on getting one of today's most advanced active subwoofers incorporating most sophisticated technology. The PowerSub 312 active 12" subwoofer with an integrated 3-channel power amplifier provides a total of 1300 watts output power. It has been specially designed for the quick and easy setup of a subwoofer satellite system. Two passive loudspeaker systems like for example DYNACORD D8 are needed as satellites, which are simply connected at the designated Speakon outputs of the PS312. Manufactured from multi-ply wood the PowerSub 312 withstands even the hardest strain during transport and operation. The integrated lightweight digital power amp with 800 W + 2 x 250 W output power optimally matches the integrated DYNACORD DND 12S400 woofer offering highest dynamic and audio performance and at the same time ensures that the DYNACORD DND 12S400 woofer is always operated in its optimum operating range. Extensive protection circuitry like Voice Coil Protection, DC/HF-Protection, Audio Limiter, Back-EMF Protection and Thermal Protection are employed to securely monitor the compliance to these operating limits, which guarantees that the PowerSub 312 provides outstanding performance even under most demanding and most unfavorable conditions. Compared to usual Class AB-operated amps the utilized "Class D digital technology", produces significantly less power loss, reducing thermal stress of all components. All controls are recessed to provide optimum protection for the sensitive parts of the PowerSub 312 even during transportation. Two stable carrying handles and an integrated threaded pole-mount flange allow comfortable transportation and optimum, space saving installation. Position the master faders on the mixer to their minimum setting. Plug the blue PowerCon connector into the blue `Mains In` socket. 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. However, the sound will suffer from spurious distortion. Slowly raise channel fader and master faders on the mixing console to the desired positions ­ i. 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. Individual sound adjustments necessary can be made using the controls of the mixer's corresponding input channels. [. . . ] Lowering input levels can prevent input clipping before it occurs. During normal operation this switch should be left at the 100Hz setting. Each output has an output capacity of up to 250W into 4 ohms. In other words, up to two loudspeaker systems with 8 ohms impedance can be connected in parallel per output. [. . . ]
