NOTE:

SAFETY COMPONENT ( MUST BE REPLACED BY ORIGINAL PART )

Congratulations! Your new DYNACORD MADRAS M18 is an active loudspeaker cabinet incorporating state-of-the-art technology.

The MADRAS M18 is an active, optimally vented subwoofer with integrated controller and ElectroVoice EVX180B woofer.

The integrated controller with 124 Hz, 24dB/octave and Linkwitz-Riley characteristics and the electronically balanced XLRF-type connectors allow easy installing an active 3-way system configuration using active top-parts like for example the MADRAS M18 (in mid-high position). Frequency and phase responses of the MADRAS M18 also provide the possibility for direct parallel operation with suitable full-range cabinets. Achieving this is possible by simply feeding the MADRAS M18 Sub with a line level audio signal from a separate mixer output. Balance between MADRAS M18 Sub and top-parts can be established from the mixing console.

An 800W high-efficiency class-H power amplifier provides ample power. Consequential use of class-H technology reduces power dissipation, power consumption as well as the power amp's weight noticeably. The power amplifier is convection-cooled, resulting in no disturbing noise from running fans.

The fully electronic VOICE COIL TRACKING PROTECTION prevents the EVX180B woofer from being damaged by thermal overload, which make the MADRAS M18 especially suitable for a wide range of demanding applications in the rental business. The birch multi-plywood enclosure is sealed with black, extremely shock-resistant structural lacquer finish. A robust, powder-coated steel grille protects the woofer against mechanical damage.

Mains connection is provided via lockable PowerCon connector. Also provided is a PowerCon mains output. Audio signal connection is provided via XLRF-type connector. An additional XLRF-type connector allows feeding the signal to another cabinet. The electronically balanced input features a level control for matching the volume. Four stable carrying handles as well as four professional-type castors allow for comfortable transport. Snap-in drillings allow trouble-free, stables stacking while an integrated polemount flange permits space-saving installation with top-parts.

UNPACKING & WARRANTY

Open the packaging and carefully take out the MADRAS M18. In addition to the appliance itself and this owner's manual, the package also includes mains cord, level control cover and warranty certificate. Please make sure to keep warranty certificate and original invoice, stating the date of purchase, at a safe place.

INPUT

Electronically balanced input for the connection of high-level signal sources like mixing consoles or signal processors. Connections can be established using phone or alternatively XLR-type connectors.

Caution: Preventing the occurrence of spurious noise. Prior to connecting/disconnecting the input, set the level control to its counterclockwise stop.

OUTPUT

This connector is connected in parallel to the input allowing the through connection of the input audio signal.

LEVEL

dB-scaled level control for adjusting the power amp's overall amplification. To prevent distortion and clipping of pre-linked mixing consoles, the control should generally be set to a value between 0dB and +6dB.

LIMIT brief blinking indicates that the power amplifier is operated at its limits. Short-term blinking is uncritical, because the integrated limiter compensates minor distortion. Constant lighting of the LED indicates that the sound is negatively affected. Reducing the output volume is strongly recommended.

SIGNAL indicates the presence of an input signal.

THERMAL lights, when the power amp's output power is reduced to prevent thermal overload.

PROTECTION lights, when one of the power amp's comprehensive protections against e.g. thermal overload, HF or DC at the output, and Back-EMF has been activated. The speaker outputs are deactivated and the input gain is reduced when in Protect Mode, to protect the power amplifier from damage.

The PROTECT LED lights for approximately 2 seconds during power-on operation. This is normal, indicating that all protections are working.

POWER-switch

Mains switch for powering the appliance on or off. With the power amplifier being switched on, the mains switch is backlit. If, after switching the power on, the switch is not backlit, please first check whether the mains cord is correctly connected. In case the cord has been connected correctly and the switch still fails to light (no function), please contact your specialist dealer.

MAINS FUSE

Under normal circumstance the mains fuse only blows in case of failure. Always use an identical type with the same current, voltage and blow characteristics when replacing the mains fuse. If the mains fuse blows more often, please contact your specialist dealer.

MAINS IN

Mains connector is carried out as PowerCon-type socket. A fitting mains cord (5m) with PowerCon-type plug is supplied.

MAINS OUT

This PowerCon mains out socket allows the connection of additional MADRAS cabinets, e.g. M15 or M18, using special cords (PC150 or PC800).

To prevent mains network overload, connecting more than three MADRAS cabinets to a single mains outlet (10A-16A) is not recommended.
