Key Features

High-Quality Audio Components

The DM-40 speakers inherit audio components from Pioneer DJ's professional S-DJX series, ensuring superior sound reproduction. This includes 4-inch fiberglass woofers for tight, punchy bass and ¾-inch soft dome tweeters.

Front-Loaded Bass Reflex System

A front-loaded bass reflex system with grooved ducts reduces air friction, delivering clear and powerful bass even when the speakers are placed close to a wall. This design ensures a robust low-end response without unwanted resonance.

DECO Convex Diffusers for Wide Sweet Spot

Pioneer DJ's DECO (Diffusion Effectual Convexity by Olson) technology is integrated into the tweeters. These convex diffusers channel high frequencies left, right, and up, creating a wider sweet spot and a 3D stereo sound experience, ensuring optimal sound quality regardless of your listening position.

Balanced Sound and Reduced Resonance

The tweeter and woofer positions are carefully aligned to eliminate crossover and ensure a balanced sound across all frequencies. Curved front edges of the cabinet further reduce resonance, contributing to a clean and clear audio output.

Setup Guide

Follow these steps to set up your Pioneer DJ DM-40 active monitor speakers:

1. Placement: Place the speakers on a stable, flat surface. For optimal sound, position them at ear level and equidistant from your listening position. Use the included bottom cushions to minimize vibrations.
2. Connect Speakers: The DM-40 comes as a pair, with one active (left) speaker and one passive (right) speaker. Use the provided 2m speaker cable to connect the 'OUTPUT TO RIGHT SPEAKER' terminals on the active (LEFT) speaker to the input terminals on the passive (RIGHT) speaker. Ensure correct polarity (red to red, black to black).
3. Connect Audio Source: Connect your audio source (e.g., DJ controller, computer, smartphone) to the active (LEFT) speaker using either the RCA inputs or the 3.5mm stereo mini-jack input. An audio converter cable (3.5mm stereo mini plug to RCA) is included for convenience.
4. Power Connection: Connect the power cord to the active (LEFT) speaker's 'AC IN' port, then plug it into a suitable power outlet.
5. Power On: Locate the 'POWER' switch on the rear of the active (LEFT) speaker and switch it to the 'ON' position. The power indicator LED on the front of the active speaker will illuminate.

Operating Instructions

• Volume Control: Adjust the overall volume using the volume control dial located on the front of the active (LEFT) speaker. Turn clockwise to increase volume and counter-clockwise to decrease.
• Headphone Output: For private listening, plug your headphones into the 3.5mm HEADPHONE MONITOR output jack located on the front of the active (LEFT) speaker. Plugging in headphones will mute the speaker output.
• Auto Standby: The DM-40 speakers feature an auto-standby function. If no audio signal is detected for a certain period, the speakers will automatically enter standby mode to conserve power. They will automatically resume operation when an audio signal is detected again.

Maintenance

To ensure the longevity and optimal performance of your DM-40 speakers, follow these maintenance guidelines:

• Cleaning: Regularly wipe the speaker cabinets with a soft, dry cloth. Avoid using abrasive cleaners, waxes, or solvents as they may damage the finish.
• Ventilation: Ensure that the speakers have adequate ventilation. Do not block any ventilation openings.
• Environment: Avoid exposing the speakers to extreme temperatures, humidity, direct sunlight, or excessive dust.
• Handling: Handle the speakers with care. Avoid dropping them or subjecting them to strong impacts.
