Description

The DM™112 is a two-way sound reinforcement system based on a heavy-duty 12” woofer and a DX™14 titanium diaphragm dynamic compression driver mounted on a 110 by 80 degree coverage Quadratic Throat Waveguide™. It’s contemporary appearance coupled with exceptional performance offer an highly desirable combination.

The light yet durable injection-molded plastic enclosure with molded-in stand mount cup eases portable use for live music or PA sound. The trapezoidal cabinet has three handles for ease of portability, and two extra angled sections on either side to allow use as a floor monitor. A full length black powder coated perforated steel grille provides system protection and a professional appearance.

The heavy-duty 12” woofer has a warm punchy sound for plenty of bass. The DX™14 compression driver tweeter is coupled to a Quadratic Throat™ constant directivity waveguide, covered under US patent #6,059,069 with

smooth, even response, low distortion and good high frequency dispersion.

Advanced Digital Signal Processing (A.D.S.P.) provides the crossover function, driver limiting, as well as the driver EQ to enable the speaker system to provide an accurate and neutral sound for any type of music. The DSP processing uses 64 bit double-precision to insure accurate and transparent sound processing, and the input/ output sections use a 96 kHz sampling rate at 24 bits for maximum fidelity. Low-jitter clocking and professional grade components insure the sound quality is superb.

An extremely flexible system of user presets and adjustments is implemented in the speaker system’s DSP computing core, and accessible via the rotary push-to-select knob and the LCD display. A total of 32 presets is available, with Factory presets made available, and room for user presets to be stored in memory, that are based off of the Factory presets as starting points.

User adjustments include: bass and treble tone controls, polarity, and signal delay, all of which can be saved under a User preset that is named with up to 16 alpha-numeric characters.

Thus, once a preferred set-up has been determined for a particular venue or typical use, these settings can be saved and recalled easily.

The DM™112 speaker system power amplifiers providing the bi-amplification are low-distortion ultra-reliable fan-cooled units providing a total of 660W peak available dynamic power for the system.

There is 410 W peak available dynamic power for the woofer, and 250 W peak available dynamic power for the tweeter. The power supply for both amps is a linear type for good reliability coupled with low cost. Both amplifiers feature sophisticated signal compression, which virtually eliminates audible power amplifier clipping. Cooling is provided via a low-noise fan, for reliable operation under any conditions.

A built-in dynamic bass boost function provides the maximum amount of bass in such a small package.

Input is via a combo female XLR and 1/4” TRS phone jack with balanced input to the DSP preamp/EQ electronics, and a Gain control. A Mic/Line switch allows for use of a microphone via the extra gain available when in the “Mic” position.

A Thru output has a male XLR jack. This output allows linking of additional speaker systems, or feed of the signal to a powered subwoofer, etc.

Applications

The Peavey DM™112 has a variety of applications such as sound reinforcement, public address, side fill system, karaoke or musical playback.

A typical signal source for the line-level inputs of the Peavey DM™112 would be a sound reinforcement mixing console (mixer) or the output from a CD player, MP3 player or tape deck. A dynamic microphone can be connected directly via the XLR input and used when the Mic/Line switch in placed into the “Mic” position as well.

ON-OFF SWITCH (1)

This rocker switch supplies AC power to the DM™115 when switched to the ON position. The ON position is with the left side of the switch pushed “in” or nearly flush with the rear panel.

FUSE (2)

The unit is AC power line fuse protected from overloads and fault conditions with a slow-blow 5 x 20mm 250V fuse. This fuse is located within the cap of the fuse holder. If the fuse fails, THE FUSE MUST BE REPLACED WITH THE SAME TYPE AND VALUE IN ORDER TO AVOID DAMAGE TO THE EQUIPMENT AND TO PREVENT VOIDING THE WARRANTY!

The fuse in the DM™112 can be replaced with a time-delay type 5 x 20 mm size 250V rated fuse.

For 100-120VAC operation, a fuse rated at 4 amps should be used. In the USA, types GDC, GMC, 215, 218, and 477 cartridge-style 5 x 20 mm size fuses with a 4 amp 250V rating can be used.

For 220-240VAC operation, a fuse rated at 2 amps and 250V should be used, which conforms to the international fuse classification “T2AL”.

If the unit continues to blow replacement fuses, do not keep replacing them, it should be taken to a qualified service center for repair. To replace the fuse, be sure to remove the IEC power cord from the IEC socket.

IEC POWER CORD CONNECTION (3)

This receptacle is for the IEC line cord (supplied) that provides AC power to the unit. It is very important that you ensure the DM™112 has the proper AC line voltage supplied. You can set the proper voltage for

your DM™112 using the Voltage Selector switch (3) on the rear panel of the unit.

Please read this guide carefully to ensure your personal safety as well as the safety of your equipment. Never break off the ground pin on any equipment. It is provided for your safety. If the outlet used does not have a ground pin, a suitable grounding adapter should be used and the third wire should be grounded properly. To prevent the risk of shock or fire hazard, always be sure that the mixer and all other associated equipment are

properly grounded.

VOLTAGE SELECTOR SWITCH (4)

The DM™112 has a voltage selector switch to allow switching between an input power voltage of 120VAC to a range from 220VAC to 240VAC, all at either 50 or 60 cycles per second (Hz). It should be set to the proper voltage for your country out of the box. However, world conditions are such that some areas have power line voltages differing from the voltage used by the majority of any given locale.

Be sure to check the position of the voltage selector switch to see that it matches the power line voltage used locally. If it does not match, then to change the voltage to the correct one, follow the steps outlined below.

Changing the Voltage Range of the DM™112

First, make sure the DM™112 is disconnected from the power line, and that the power switch (4) is in the OFF position.

Second, unscrew the screws holding the clear switch protector on the voltage selector switch (3) just a little, just enough to allow rotation of the clear switch protector. The screws DO NOT need to be unscrewed very far.

Third, rotate the clear plastic protector about 90 degrees to uncover the voltage selector switch. One side of the cover has a slot; the other just a hole. The side with the hole is the side that pivots.

Fourth, using a small flat blade screwdriver, push the red selector switch slide plate to the other side from where it was. The voltage that is now visible on the red slide plate is the one you have selected.

Fifth, rotate the clear plastic protector back underneath the loosened screws, and tighten one down while holding the clear plastic protector in place. Tighten the other screw down, and make sure both screws are tight.

If the screws are over-tightened, this could damage the voltage selector switch clear plastic cover, so do not apply excessive force to the screws!

Sixth, the fuse should be changed to the correct amperage rating. For an input power voltage of 120VAC, use a 4 amp rated, 250V 5 x 20 mm cartridge type time-delay fuse, which conforms to the international fuse classification “T4AL”.

For an input power voltage range of from 220VAC to 240VAC, use a 2 amp rated, 250V 5 x 20 mm cartridge type time-delay fuse, which conforms to the international fuse classification “T2AL”.

The IEC power cord that is correct for your locale can now be plugged into the IEC receptacle (2), and the Power switch (4) activated to turn on the powered DM™112 speaker system.

ON-OFF SWITCH (4)

This rocker switch supplies AC power to the DM™112 when switched to the ON position. The ON position is with the top side of the switch pushed “in” or nearly flush with the rear panel.
