Introduction Thank you for choosing the Studiophile DX4 professional desktop audio monitoring system. Top recording engineers and producers in studios around the world use M-Audio’s Studiophile Series monitors. With the Studiophile DX4s, you can enjoy the same professional standard of audio quality right on your desktop. The Studiophile DX4 has been designed and tested by veteran audio engineers to meet your needs in a desktop audio monitoring environment.
Enclosure - Just as the other components do, the DX4’s enclosure plays an important role. In order to provide more stable performance, the DX4’s enclosure employs a special high-density MDF and unique interior reinforcement designed to absorb vibration and impact generated under extreme conditions. Network and Power Amplifiers - The active equalization, crossover networks and power amplifiers for the DX4 are specially designed for this woofer and tweeter.
. HEADPHONE OUTPUT JACK: This 1/8” jack outputs a stereo signal identical to the DX4’s speaker output. When headphones are plugged into this jack, the DX4 speakers are muted and headphone volume is controlled using the volume control. Rear Note: This image shows the Rear panel of the Left Speaker. The Right Speaker’s Rear panel contains only a single Speaker Terminal, for connectioin to the Speaker Terminal of this (Left) Speaker. 1.
For balanced wiring, a three-conductor TRS plug is necessary. The input wiring of the TRS input connector is as follows: < TRS TIP Signal positive (+) < TRS RING Signal negative (–) < TRS SLEEVE Signal ground (Shield) Note: Input from the TRS and RCA connectors is summed together, allowing both inputs to be used simultaneously. 3. MID-BOOST SELECTOR SWITCH: This 2-position switch selects the Mid-Boost mode setting.
Correct Power Operation: Since the DX4 contains amplifiers; it must be connected to a power outlet using the detachable AC cable that is provided. Before connecting power, please make sure that the voltage of the DX4 corresponds with the voltage you are going to plug the power cord in. WARNING! - Use of improper voltage may result in hazardous conditions and/or damage to speaker components not covered by speaker warranty.
Setting the Mid-Boost EQ Switch This 2-position switch allows you to select either the “In” or “Out” Mid-Boost mode. The Out mode produces a flat midrange response for normal monitoring and listening conditions. The In mode will move the sound stage forward toward your listening position. 'Mid-Boost In' Placing the DX4 Placing the speakers is one of the most important considerations in accurately monitoring sound.
3. Place the Left and Right DX4 units verticallyand right side up. Placing the DX4 monitors horizontally is not recommended. Important: DO NOT place any obstacles that may block the flow of air in front of or between the DX4 monitors. Also, remove reflective materials such as glass, mirrors or metal from the monitoring environment and place those materials away from the path of the sound from the DX4s.
