Introduction

Thank you for choosing the A.V.E. analogue/digital 4-channel mixer MX-8 with four
microphone/line inputs; an outstanding unit that was designed particularly for superior
audio quality in churches.

Each microphone/line input is equipped with a compressor/limiter, 3-band equalizer,
as well as indicators for volume, operating status, and peak, respectively. An
automatic processing unit controls additional functions, such as priority, ducking,
number of activated microphones, or the hold time. Furthermore, a variable graphic
equalizer with 48 bands (12 per output) allows an optimisation for every application.
16 fully parametric equalizers (4 per output), each with an individually adjustable Q­factor of up to 100, as well as an automatic gain adjustment when additional
microphones are activated provide an optimum feedback elimination.

The MX-8 is equipped with its own software. This makes programming simple and
straightforward – Laptop or PC are no longer required. Up to 20 different sets of
settings, so-called „presets“, can be programmed and can easily be recalled by the
user for each occasion as required.

This manual adresses users in sections 2., 3., and 4.1. These parts of the manual
deal with explaining the components of the unit and describe the basic operation.
The following part is addressed to the qualified technical personnel in charge of
extended programming and internal modifications.

Front panel of the MX-8

1. Volume control (for channels 1 – 4): Allows adjustment of the level of the
signal sources connected to the microphone/line inputs (26.). During installation
by the technician, the optimal level will be marked on the unit.

2. Level indicator (for channels 1 – 4): 4-level LED indicator. The maximum level
of +5 dB indicates that the input is overdriven.

3. Gate indicator (green LED; for channels 1 – 4): Optically indicates an
activated input. The processor automatically determines which of the inputs is
activated. The level difference at which an additional microphone is opened, can
be set by an internal modification (see section 4.3.4).

4. Channel selector CD/tape: Choose between music rendition via CD or tape.
The selection is indicated by one of the LEDs (5. or 6.). Consumer-level audio
equipment such as CD or cassette player are connected on the back to inputs
(24.) or (25.), respectively.

5. LED indicator CD: Music rendition via CD

6. LED indicator tape: Music rendition via tape

7. Volume control for CD/tape

8. Level indicator for CD/tape: A level of +5 dB indicates that the input is
overdriven.

9. Low-frequency level control for CD/tape: Controls (9.) and (10.) allow an
optimisation of the sound characteristics of the music rendition.

10. High-frequency level control for CD/tape

11. Volume control for headphones: Input (12.) allows the connection of
headphones for monitoring purposes, the volume of which can be adjusted with
this control. Which of the 4 outputs is to be directed to the headphones can be
selected in the parameter menu (as described in section 4.2.3).

12. Connection for headphones

13. LCD display: The bright display contributes to the clear and user-friendly
operation of the MX-8. (The contrast of the display can be adjusted in the
parameter menu as described in section 4.2.3.)

14. Volume/Value knob: Rotary encoder with integrated pushbutton. This knob is
used, among others, to set the overall volume or set other values.

15. Preset/Parameter knob: Rotary encoder with integrated pushbutton. This knob
is used, among others, to switch from one preset to another.

source.

17. Fuse: 315 mA

18. Main on/off switch

19. Output: Output connectors (to power amplifiers, etc.)

20. Direct OUT: Direct output without any signal processing. This output can be
used for capturing and transmitting the ambiance of e.g. a mass to external
rooms.

21. Level Direct OUT: Controls the output level of the direct output

22. Link in: Permits multiple mixers to be linked, creating additional inputs.

23. Link out: Output when linking multiple mixers

24. Tape-recording: Phono connectors for tape-recording

3 Basic operation of the MX-8

3.1 Programmable settings („presets“)

The MX-8 combines numerous integrated functions with very simple operation.
Even in acoustically difficult environments, best results are achieved. So-called
„presets“ can easily be programmed. No less than 20 of these preset slots
