DESCRIPTION

Congratulations! 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. The enclosure is sealed with a scratch-resistant, hardwearing 2K-lacquer finish. A robust powder-coated steel grille protects the DYNACORD DND12S400 woofer against mechanical damage. 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.

Unpacking and Warranty
Open the packaging and carefully take out the PowerSub 312. Remove the protective foil from the carrying handles. Mains cord and warranty card are supplied in addition to this owner’s manual. Please make sure that all details are filled in on the warranty card. Only a completely filled in warranty certificate entitles you to stake any warranty claims. Keep the original invoice together with the warranty card at a safe place.

Setup and Connections
Place the PowerSub 312 on an even ground, using the rubber feet to ensure safe and steadfast operation. Make sure to check the stability of the system when using pole-mounts installed in the PowerSub 312. Do not cover the subwoofer’s rear during operation. Otherwise, thermal overload could cause the PowerSub 312 to enter power reduction mode, which reliably protects the unit from being damaged. However, in this mode full output power is not available. Mains power is supplied via Neutrik’s professional PowerCon connector system and by use of an extremely long (5m) mains cord. This ensures absolute secure and reliable connection to the mains outlet. Nevertheless, using high-quality mains distributors that allow high power consumption and offer reliable protection throughout the entire system is strongly recommended with large installations consisting of several active cabinets.
Before establishing the mains connection for the first time, make sure that the cabinet’s operating voltage setting, which can be found on a label next to the mains switch, corresponds to your local mains network.

QUICKSTART

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’sGaincontrol so that the greenSIGnalLED lights. The redPeaK` 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.

CONTROLS

Input L, Input R
Electronically balanced inputs for the connection of LINElevel signal sources such as mixers, signal processors, etc. Establishing a connection is possible via phone or XLR-type plugs. Whenever possible, balanced signal feed is always preferable to guard against potential noise or HFinterference.
Caution: Before making any connections or disconnections, make sure to set the corresponding level controls to their counterclockwise stop.
The input section of the PowerSub 312 also allows MonoSub operation. The stereo signal needs to be fed to the L and R inputs and the low-frequency range signals of both channels are summed prior to being processed in the power amplifier section. All other applications employ only the (L)/Mono input.

Parallel Outputs L/R
Connected in parallel to the input jacks, these connectors are used for “carrying through” the input signal.
CLIP indicates, when lit, that the internal power amplifier is actually operated in the border range before clipping. Short-term blinking is uncritical because the amp’s audio limiter keeps distortion under control leaving the sound unaffected. Constant lighting of this indicator signals that the input section is probably overdriven and sound degradation could be the result. Lowering input levels can prevent input clipping before it occurs.

SIGNAL Indicates that an audio signal is present at the input and that it is output as well.

X-OVER
This switch allows changing the x-over frequency between subwoofer and satellites. During normal operation this switch should be left at the 100Hz setting. Set the x-over switch to 140 Hz when using compact satellite cabinets, e.g. VL62. For large-size cabinets, e.g. D12, set it to 70 Hz.

SUB LEVEL
This control sets the output volume of the PowerSub 312 in a range between -dB and +10dB. The center position represents 0dB.

SPEAKER OUTPUTS
These outputs are for connecting the satellite cabinets, e.g. Dynacord D8. 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.

EXTERNAL SUB OUTPUT
This output allows connecting an additional passive subwoofer, e.g. SUB 112. Maximum output capacity is 400W into 8 ohms.

POWER switch
Mains switch for switching the unit’s power ON or OFF. The mains switch lights after switching on the PowerSub 312. In case the switch is not lit upon switching on the power, make sure that the mains cord is connected correctly. If this is the case and the PowerSub 312 still shows no function, please contact your local dealer.

MAINS IN
The mains connector is carried out as a PowerCon socket. A suitable 5m long mains cord with PowerCon plug is supplied.
