DX8 – 3 2. INTRODUCTION The DX8 is a DSP-based digital audio mixer and signal processor designed for use in a variety of installations such as churches, courtrooms, convention centers, and hotels. It provides eight universal inputs and two balanced outputs allowing true 8x2 mixing for stereo or dual-zone applications.

DX8 – 11 Applica tion Dia grams A: T yp ical S tere o Applica tion This diagram depicts a simple setup, using the DX8 in a stereo application. A microphone is connected to the MIC input on channel 1 for paging purposes, and several program sources are connected to the LINE inputs on channels 3 through 8.
DX8 – 12 C onnectio ns C onnect ing Bal anc ed Sourc es Use high-quality three-conductor cable for balanced connections, such as Star Quad by Belden, Canare, Mogami, etc. The better the shield, the better the audio signal is protected from induced EMI and RFI.
DX8 – 13 Strip the wire back about 1/4" inch, insert the wire as far as it will go into the appropriate hole in the supplied Phoenix-type connector , and tighten down the screw with a small slot-head screwdriver . It is recommended that you use 20 or 22 gauge wire with the Phoenix-type connectors.
DX8 – 14 4. OPERA TION Set the Lev els MIC and LINE Input T rim The analog trim controls on the rear panel are not adjustable via the control software since these are in the analog domain, prior to the A/D converters. T o adjust the MIC and LINE TRIM controls: 1.
DX8 – 15 Bus A and B Inpu t T rim There is no metering after the BUS A and B input TRIM controls. These controls must be adjusted by ear . Start the program source playback for all sources connected to the BUS A or BUS B input. Slowly increase the TRIM control to the center position (12 o'clock), which is unity gain.
DX8 – 16 DIRECT OUTPUTS The DIRECT OUTPUTS provide an unbalanced line-level signal from each of the 8 Input channels. This signal comes from the output of the preamplifier stage on each input channel, prior to the A/D converter and subsequent digital signal processing.
DX8 – 17 The logic functions assigned to each individual logic input and output are configured using the DX8- PC application. In addition, each logic input and output can be assigned a descriptive name (up to 32 characters) for easier identification within the PC application.
DX8 – 18 Upgradin g the So ftware From time to time, Mackie Designs will release upgrades for the internal operating software in the DX8. This can be downloaded from our website ( www .
DX8 – 19 Ov erv iew The DX8-PC software application provides real- time control and configuration editing for the DX8 using a laptop or other PC-compatible computer .

Close Win dow (ESC) This closes the window that is currently selected (front-most) on-screen. Cl ose All (C trl+/) This closes all windows that are currently open on the screen, leaving just the main window open.
DX8 – 22 Presets The DX8 stores up to 16 presets, which can be recalled via the Presets drop-down box. Select a preset in the drop-down box and the settings are instantly recalled from the DX8 memory . Sa ve T o Pre set Click this button to save the current mixer settings on the DX8 to a preset.
DX8 – 23 But t on s V iews These four buttons open the Graphic EQ, Parametric EQ, Output Compressor , and Automix views, overlaid across the input section. Graphic EQ Click this button to open the 31-Band Graphic Equalizer window for the A and B outputs.
DX8 – 24 C ompres s • Ratio: This determines the change in output level as a function of the change in input level, once the threshold has been exceeded.
DX8 – 25 Each individual channel is attenuated by an amount, in dB, equal to the difference, in dB, between that channel ’ s level and the sum of all the channel levels. This keeps the overall system gain constant, and allows the system to deliver maximum acoustic gain without feedback.
DX8 – 26 Use a control group to adjust the volume of two or more channels at the same time. All faders that are assigned to a control group will have their gain settings modified by the amount the control group fader is increased or decreased.
DX8 – 27 Action Definitions Momentary means that the logic function is active as long as the Logic Input is held active. When the Logic Input is inactive, the logic function is inactive. Latch On means that the logic function is active and stays active once the Logic Input changes from inactive to active (logic high to logic low).
DX8 – 28 Mid Peaking EQ These two knobs control the gain ( ± 15 dB) and the center frequency (20Hz-20kHz) of the channel mid-frequency peaking EQ. Click and drag up or down to increase or decrease the settings of these controls. The actual settings are displayed in the two boxes above the knobs.
DX8 – 29 Out put S trip Mete r The output meter indicates the output signal level just after the output gain control and just prior to the D/A converter stage.
