The M4 has been designed to give you years of trouble-free use with excellent performance. Although it is relatively easy to use, you will find hookup and operation simpler if you spend some time reading this manual to familiarize yourself with the M4's many features. FEATURES • 16 or 24 mono input channels that can route signals to 4 subgroups, 6 aux sends, stereo and mono master outputs. Each channel has balanced XLR microphone inputs and balanced TRS 1/4-inch line jacks. • 4 stereo input channels provide stereo input routing to the four subgroups, 6 aux sends (2 pre/4 pre or post) and to the stereo master outputs. Each stereo input channels has a fixed 2-band EQ. • Each mono input channel is equipped with 6 aux sends (2 pre-fader/EQ, 4 switchable pre or post-fader/EQ). A selector switch on each channel allows a choice of signal routng to aux 3 / 4 or to Aux 5/6. Four stereo aux returns allow excellent signal routing potential. 100-mm faders are provided for more precise mix control. • Each mono input channel has 3-band EQ with semi-parametric mid range that provides excellent sound tailoring capabilities. • 4 subgroup mixing busses, each with its own 100 mm fader, signal routing and mute switches, gives additional routing and mix capabilities. • Each mono input channel is equipped with insert input/output allowing connection of signal processors independently on each channel. A separate direct output alloes signal routing for recording. • Each subgroup and the master stereo outputs have insert input/outputs and balanced TRS inputs allowing connection of sub-mixers or other processors independently on each output. • After-Fade Listen (AFL) allows monitoring of the output signal from each subgroup output and aux send through headphones at any time. • Separate tape inputs and record outputs allow easy connection of CD players and tape decks for playback and recording. • Universal 48 V phantom power is provided for powering condenser microphone and direct boxes. • A BNC-type LittleliteR connector is provided for connection of a lamp to illuminate the panel. PRECAUTIONS 1. AVOID EXCESSIVE HEAT, HUMIDITY AND DUST Keep the mixer away from locations where it is likely to be exposed to high temperatures, oppressive humidity and dust. These elements are potentially harmful to any piece of electronic equipment. 2. VENTILATION The mixer has ventilation slots on the side and bottom panels. Do not block these vents or prohibit airflow into them. 3. AVOID STRONG PHYSICAL SHOCKS AND VIBRATION Although the M4 is designed to handle the rigors of transportation, strong shocks and vibrations can cause damage. Care in handling during transportation will improve operational reliability. 4. DO NOT OPEN THE CHASSIS OR PERFORM MODIFICATIONS The M4 contains no user-serviceable parts. Refer all maintenance to qualified service personnel. Opening the case and tampering with the circuitry will void the warranty (see the warranty statement at the end of this manual for details). 5. TURN THE POWER OFF BEFORE MAKING CONNECTIONS Turning the power off before connecting or disconnecting cables will eliminate potentially harmful and annoying hums and buzzes. Handle cables carefully and grip them by the connector, not the cable. 6. CLEAN WITH A SOFT, DRY CLOTH Avoid cleaning the mixer with solvents such as benzine or thinners. Wipe the panel clean with a soft, dry cloth. page3 М4 MIXING CONSOLE 1. MONO INPUT SECTION 1. PEAK INDICATOR This indicator detects peak signal level after the EQ and will light red 3 dB before clipping to warn of the onset of clipping distortion. This light is useful in setting the gain control optimally. GAIN CONTROL This control is used to adjust the input signal to the appropriate evel. The best balance of dynamic range and signal-to-noise ratio can be achieved if the level is adjusted so that the peak indicator flashes occasionally on the loudest passages. INPUT SELECTOR 2. 3. 4. 5. 6. This switch selects the appropriate input for the channel. When the switch is in the up position, the 3-pin XLR-type microphone input is selected. When the switch is depressed, the Vi-inch line input is selected. HIGH-PASS FILTER This switch controls a high-pass filter that rolls off signals below 80 Hz at 12 dB-per-octave. By engaging the high-pass filter, you can minimize stage rumble, wind noise, p-pops and other unwanted low-frequency noise. EQ SECTION The EQ section is a 3-band equalizer with the following properties: HIGH: Shelving-type, ±15 dB at 12 kHz MID: Peaking-type, ±15 dB, variable from 250 Hz - 5 kHz LOW: Shelving-type, ±15 dB at 80 Hz The frequency response is flat when the controls are in their center (detented) positions. AUX 1 - 6 CONTROLS These controls regulate the amount of the channel’s input signal that is sent to each respective aux sends for further routing. Aux 1 and Aux 2: These controls regulate the amount of pre-fader, pre-EQ signal (typically used for mo...
