Page 3: Mz-Series Overview
MZ-SERIES OVERVIEW The MZ Series from HH is a range of high-performance commercial install amplifiers and pre- amplifiers. Providing industry leading audio performance and ultra high power in a compact 1U enclosure. Remote control options are available using a standard CAT5 cable allowing easy installation. -
Page 4: Controls
CONTROLS NOTE: This image is a representation of the MZ-140Q, other models follow a similar layout 1. INPUT LEVELS Each input allows granular control of the input sensitivity. By default, you should ensure these are all set to the centre position which is unity gain. •... - Page 5 4. POWER SOCKET Connect the included IEC power cable here. The MZ series includes a universal AC 100-240V~ 50/60Hz power supply and can be used worldwide without modification. The power switch will isolate the mains power from the unit. 5. ZONE OUTPUTS 5.08mm Euro block connectors are provided to connect to your loudspeakers.
- Page 6 9. INPUT 5 Input 5 consists of a stereo 3.5mm stereo AUX in socket along with a stereo RCA socket. All inputs are summed to mono internally. Don’t connect balanced signals here. 10. INPUT 3 & 4 Dual balanced 3.5mm Euro block inputs are provided per input channel to connect to a line level output.
- Page 7 12. DIP SWITCH SETTINGS The MZ-64P has a limiter for each ZONE that can be toggled on or off here. There are additional settings for the limiter threshold level to match your power amplifiers sensitivity along with power saving mode and front panel lock switches. See LIMITERS FRONT PANEL LOCK.

Page 8: Installation Guide
INSTALLATION GUIDE We recommend following the installation procedure below in the order it is written to ensure safe use of your MZ product. Pay attention to any notes or warnings throughout this document to keep your devices protected. It is advisable to perform a test installation before making any permanent installation measures. Fully wire up all input devices, speaker connections and wall controllers to ensure full functionality beforehand. -
Page 9: Power
POWER Your MZ is powered by an IEC power cable and contains a universal 100-240V~, 50-60Hz power supply. Connect the included IEC cable to the MZ amplifier and the other end to a suitable mains source. Don’t turn on the MZ until all input and output connections are made. Once turned on, the front panel LEDs will run through their startup cycle which will take a few seconds, and the power LED on the front will light a solid green to indicate that it’s complete. -
Page 10: Mounting
MOUNTING All MZ series models are designed to fit a 1U rack mount. 2 rack wings are provided along with 6 screws to allow your model to be securely fastened to a shelf. When choosing a location for mounting your amplifier, make sure you are choosing a rack location away from other heat sources, as well as preventing any foreign bodies from entering the chassis. -
Page 11: Wiring
WIRING Follow these steps when wiring up a Euroblock connector. You will need a flathead screwdriver with a 1.2mm or smaller head, as well as wire strippers (not provided). 1. Strip back the insulation using wire strippers, leaving around 7-10mm of exposed cable to allow ample wire to go into the plug. -
Page 12: Inputs
INPUTS The MZ models have 4 different types of input connectors: EUROBLOCK, RCA, AUX, and XLR. The input cable required will depend upon the device being connected. Two combi XLR and 6.3mm jack connectors, typically used with a microphone, mixer, or audio interface. - Page 13 The 2 XLR inputs each have 4 settings per input. It is advisable to set them up prior to start up. LINE/MIC LEVEL - Changes the input sensitivity depending on the setting. Inputs from an audio interface should use line level (0dBu gain). Switch to MIC if connecting a microphone to add 40dB gain.
- Page 14 Two sets of balanced EUROBLOCK L/R inputs. If your input is mono, it can be plugged into either port. Your MZ will come with some provided EUROBLOCK male plugs to wire your cable into. Note the order of the pins for each socket when wiring. For a balanced input, connect the wires to the EUROBLOCK connector Hot = +, Cold = -, Ground = G.
- Page 15 When the EMERGENCY override switch pins are closed, the amplifier will stop all signals from all inputs and override them with whatever signal is on the emergency in signal pins. The EQ and front panel ZONE volume controls will still be respected to ensure maximum levels are adhered to. However, any wall controller volumes will be set to their maximum level, ensuring the EMERGENCY input is heard at the maximum set volume regardless of mute state.

Page 16: Outputs
OUTPUTS MZ amplifiers can drive either LoZ (4 or 8 ohm) or HiZ (70V or 100V) loudspeakers via a 5.08mm EUROBLOCK connector. Each zone will need two connections, positive and negative. Pay attention to which setting your ZONE speakers will use, HiZ or LoZ, as this will affect which pins should be connected (see image below). - Page 17 HiZ MODE Connect to a 70/100V speaker line, which can be distributed around a large area. The total power consumption of all speakers on the same ZONE output, plus 10% for cable losses, must add up to less than the amplifiers output power. For example, an MZ-280Q is rated 240W in 100V mode so you may connect Eleven TNi-C8 loudspeakers running in 100V/20W mode (20W*11 = 220W) allowing a safe margin.
- Page 18 LoZ MODE Make sure to check the combined impedance of all the speakers you are connecting to a zone – this should be equal to the LoZ setting (4 or 8 ohm) that it’s set to. If you have multiple low impedance speakers going into the same ZONE, these can either be connected in series or parallel like so: Doing so will affect how the total impedance of that zone should be calculated.
- Page 19 The table below should be used for reference when working out the total power ratings of speakers: HIZ / LOZ POWER RATING MODE 280Q* 140D/140Q** 4 OHM 280W 8 OHM 245W 140W 250W 140W 100V 240W 120W *250W max when running from a 120V mains voltage **130W max when running from a 120V mains voltage Each ZONE on the 64P uses a 3.5mm, balanced 3 pin EUROBLOCK socket.
- Page 20 The 3.5mm PAGING/LINE OUT EUROBLOCK connector has two separate functions. LINEOUT – A balanced line out for ZONE 1 is available on pins 3,4,5. The line out signal is post ZONE 1 volume controls so that it can be used for system expansion, for example connected to further external amplifiers.

US controllers fit a standard US junction box. The front plate has dimensions 70 x 114mm and typically uses a standard 48mm depth box. Full details are available in the MZ Series wall controller user manual available on the website. Page 20... -
Page 22: Example Connections
EXAMPLE CONNECTIONS In this example, the MZ-140D is used to power 2 ZONEs, each consisting of 2 TNi-W8/12PRO speakers at the low impedance 4ohm setting (two 8ohm speakers in parallel). The input comes from an audio server plugged in via 2 RCA cables to input 5, with an MZ-C2 wall controller connected via a standard CAT5e cable and set to control both zones. - Page 23 In this example, both ZONEs are connected to high impedance ceiling speakers from the HH TNi-C series. Two wall controllers are connected in daisy chain formation, one to control each ZONE and a fire alarm switch/alarm system are both plugged into the EMERGENCY input. The DIP switch settings for the above example would be as follows: ZONES 1 and 2 in HiZ 70V (can also be 100V depending on speaker transformers) mode, and POWER SAVING MODE / FRONT PANE LOCK switched on.
- Page 24 Here the MZ-140D is used for a two-ZONE setup this time with a TNA-1200S subwoofer connected to LoZ and the TNi-W series to HiZ. ZONE 2 is configured with in high pass filter to enable the sub to be used without additional filtering. An additional microphone is plugged into XLR channel 2, where the priority can be turned on to automatically duck the other inputs when used.

Page 25: Operation
OPERATION TEST STARTUP Once all inputs and outputs are wired correctly and plugged into the ZONE amp, an initial test run should be carried out. When first powering up your amplifier follow these steps: 1. Check all back panel settings are correct to your setup. 2. -
Page 26: Limiters
LIMITERS MZ series contains comprehensive signal monitoring and limiters to ensure you get the best sound. Should the ZONE LIMIT LED go RED, it means the internal power amplifier limiter has switched on for that ZONE. Momentarily this is perfectly fine, however if the LED stays RED for long periods you should turn down the ZONE volume. -
