  • Page 5: Operating Instructions

    5. MIC 2 Mute (VOX Priority) Adjustment Microphone input 2 features automatic priority (VOX) over MIC/LINE channels 3 &4 plus AUX channels 1-4. To adjust the sensitivity, turn the potentiometer anti-clockwise for the clockwise to reduce the sensitivity or clockwise to increase the sensitivity. Note: when the VOX priority is activated, both MIC/ Line1 and MIC/Line2 will be activated. 6. AUX 1-4 Tone Control During initial setup the high frequency and low frequency tone adjustments should be set to the zero point (3 O'clock position). Turn the level control anti clockwise to reduce the high/low frequency tones, or turn clockwise to adjust the increase the high/low frequency tones. Adjustments should be made gradually to avoid any sudden changes to the audio output. 7. Zone 1 Master Volume Controls The Zone 1 master output volume is adjustable. Turn the level control anti clockwise to the lowest setting, or turn clockwise to adjust to the highest setting. 8. Output VU Meter The output level indicator (VU meter) has three green LEDs and two amber LEDs. During normal operation, the output meter should show only green LEDs. As the output reaches maximum, the first amber LED will illuminate followed by the red LED to indicate +20dB over signal. Care should be taken to keep the output signal within the green LEDs with only occasional peak’s illuminating the amber LEDs. If the Red +20dB LED is illuminated, the output volume should be reduced. www.cleveracoustics.co.uk ZM 84 Audio Mixer User Manual...
  • Page 6 AUX 1-4 channels the gain reduction must be made at the audio source or using an in-line attenuator. 14. AUX 1-4 Volume Controls Each of the AUX volumes are adjustable. Turn the level control anti clockwise to the lowest setting, or turn clockwise to adjust to the highest setting. 15. Power Switch On/Off control for the zone mixer. 16. AC Mains Power Input 240V~50Hz AC mains voltage input. This product falls under CLASS 1 and must have a protective earth connection at all times. 17. Unbalanced Line Outputs – Record outputs 3-4 Unbalanced, 0dBu mono outputs for each of the two record outputs. Each zone output features a female phono (RCA) connector. The output volume for the record outputs is fixed and is not altered by the master volume control for the zone outputs. www.cleveracoustics.co.uk ZM 84 Audio Mixer User Manual...
  • Page 7 • Input Gain: To allow the installer to match levels between audio sources, the ZM 84 features a rotary input gain control for each channel. Turn the level control anti clockwise to the lowest setting, or turn clockwise to adjust to the highest setting. • +48V Phantom Power: The ZM 84 features switchable phantom power on each of the MIC 1-4 channels for use with condenser type microphones. Selection of Phantom Power status should be made before the zone mixer is powered on. Phantom Power relies on balanced cabling for correct operation. • -30dB Attenuation Pad: To facilitate the use of line level audio sources, MIC/Line inputs 1-4 each feature a switchable -30dB attenuation pad. If the input signal is too high or known to be from a line level source, the attenuation pad should be switched on by pressing the switch to the IN position. • The ZM 84 features an 80Hz low cut filter, this can be activated via the internal jumper system. To do so, a qualified engineer must power down the unit, disconnect from power and follow the instructions in this manual to use the correct internal jumper. 23. MIC/Line 1-4 Balanced Audio Inputs MIC/Line inputs 1-4 all feature balanced, mono audio inputs, each with selectable phantom power (48V), -30dB attenuation pad and adjustable input gain (-60dB ~ +10dB) for use with MIC/ MIC+Phantom/Line signals. 24. Audio BUS RJ45 Output The ZM 84 features an RJ45 output port for linking multiple ZM 84 zone mixers. The audio routing may be selected via the internal jumper system. www.cleveracoustics.co.uk ZM 84 Audio Mixer User Manual...
  • Page 8 Power On/Off Procedure Prior to making any connection to the mains power or audio inputs/outputs, turn all level controls counter clockwise to the “min” position and all tone (equaliser) controls to the mid (zero) point. Switch on the zone mixer and any audio sources (MP3 players, CD players, Microphones etc) before powering the systems amplifier ON. The last product to be switched on should be the power/slave amplifiers to prevent any unwanted noise or potential damage to speakers or amplifiers. If you wish to power off the system, turn the amplifier’s master volume control counter clockwise to the “min” position before switching the amplifier OFF before any audio sources are switched off. By following this procedure it will prevent acoustic shocks to the speakers or potential damage to system components. After connecting all audio sources and powering on the system, adjust the level of each audio input, select the zone routing in order to achieve the desired “mix” for each zone. Care should be taken to when adjusting microphone input volumes and the master volume, adjust both of these in small increment’s to avoid feedback (howl around). The goal is to achieve a clear balance between music and voice ensuring announcements can be clearly heard. Internal Jumper System Configuration: Cascading Multiple Units: Via the AUDIO BUS IN and OUT connectors 16 units can be combined to one system so that you have available max. 64 MIC/LINE and 48 AUX inputs. The audio signal will be fed to the next unit via the “AUDIO BUS OUT“ output. Via the mute link connector the different mute signals are passed to the other units. This allows i.e. that a VOX priority of MIC1 not only mutes the inputs of the particular unit but also the inputs of the other units. By internal jumpers you can select to what external mute signals a particular unit should react. You find more details in chapter 3.5. By shortening the mute link connector all inputs of all connected units will be muted. www.cleveracoustics.co.uk ZM 84 Audio Mixer User Manual...
  • Page 9 Operating instructions Positions of Jumpers: Jumper for mono/stereo selection of AUX inputs. Jumper for low cut On/Off of Mic inputs. Jumper for input routing. Jumper for MUTE-LINK mode. Important Warning: The internal jumper system should only be adjusted by a qualified engineer with suitable electrical knowledge. Before commencing any work internally, the ZM 84 should be disconnected and isolated from the electrical supply. www.cleveracoustics.co.uk ZM 84 Audio Mixer User Manual...

    Factory setting is filter 'OFF'. Mono / Stereo: For the inputs MIC1-4 a 80Hz low cut filter can be activated for each channel by setting of a jumper. Factory setting is 'ST' (stereo). Mute Link: Configuration of the Mute-Link functions is done by these jumpers. J11.1 Output of internal mute signals activated Output of internal mute signals deactivated J11.2 Output of external VOX signals deactivated Output of external VOX signals activated J11.3 Output of external PRIO signals deactivated Output of external PRIO signals activated Factory setting is jumper J11.2, J11.3 in OFF, and the jumper J11.0 in ON position. Signal Routing: Every audio input can be individually assigned to one of the internal busses. Factory setting is all jumpers in 'ON' position. The function of the particular jumpers can be seen from the block diagram. www.cleveracoustics.co.uk ZM 84 Audio Mixer User Manual...
