ALLEN & HEATH DLIVE DM48U (01) PDF MANUAL

Before starting, read the Important Safety Instructions printed on the sheet supplied with the equipment. For your own safety and that of the operator, technical crew and performers, follow all instructions and heed all warnings printed on the sheet and on the equipment panels.

Protect the equipment from damage through liquid or dust contamination. Cover the MixRack when it is not being used for a long period.

If the equipment has been stored in sub-zero temperatures allow time for it to reach normal operating temperature before use at the venue. Recommended operating temperature is 0 to 35 degrees Celsius.

Avoid using the equipment in extreme heat and direct sunlight. Make sure the ventilation slots are not obstructed and that there is adequate air movement around the equipment.

Clean the equipment with a soft brush and dry lint-free cloth. Do not use chemicals, abrasives or solvents.

It is recommended that servicing is carried out only by an authorised Allen & Heath agent. Allen & Heath do not accept liability for damage caused by maintenance, repair or modification by unauthorised personnel.

Reversible rack ears design

All models feature the same mix engine and differ only in the number of analogue I/O and their physical size.

DM32: 32 mic/line in, 16 XLR out, 7U

DM48: 48 mic/line in, 24 XLR out, 8U

DM64: 64 mic/line in, 32 XLR out, 10U

The MixRack can be operated as a freestanding unit for shelf or floor operation. Check that its plastic feet are fitted. Ensure adequate air flow around the unit. It must not be covered in any way. Always stand the unit on a firm flat surface away from any soft furnishings or carpet.

The DM32U, DM48U and DM64U are designed as 19 inch rack mount units and occupy 7U, 8U, 10U of rack space respectively. The plastic feet may need to be removed before rack mounting; retain them for future use.

For rental, touring and other portable use, we recommend that you use a professional grade flight case with shock mounted internal rack frame.

Ensure natural convection of airflow around the unit by allowing good ventilation below, in front of and behind the unit. Rack equipment known to produce a significant amount of heat should not be mounted directly below the unit. Forced convection by means of a rack mounted fan-tray may be desirable in situations where space is restricted and the ambient air temperature is high.

The rack ears can be mounted facing either the front or rear panel to suit the application. They are secured to the sides of the MixRack with 3 screws each. Remove these screws using a Pozidriv screwdriver to remove or reposition the rack ears.

These are recallable preamps for balanced or unbalanced microphone and line level signals. Gain, Pad and 48V are digitally controlled within the preamp.

The PP indicator lights up when phantom power voltage is detected at the socket, whether internally or externally sourced.

Any socket can be patched to any Input Channel using the I/O or Processing / Preamp screen.

These are line level, balanced XLR outputs with a nominal level of +4dBu. The outputs are relay protected to prevent power on or off thumps. Signals can be patched to any output socket using the I/O screen.

There are 3 audio interface ports, each providing 128×128 channels, that are independently assignable. Fit one of the available option cards for system expansion, digital mic splitting, recording or distributed audio networking. Use the I/O screen to patch signals from or to the I/O Ports.

iLive / GLD option cards (M-Dante, M-Waves, M-ES-V2, M-ACE, M-MADI) can be used with dLive when fitted with the M-DL-ADAPT ‘letter-box’ adapter. This provides a 64×64 48kHz interface with built-in Sample Rate Conversion.

There are 2x RJ45 Gigabit Ethernet ports. Connect a laptop or a wireless router to use with dLive Editor or iOS apps. All devices on the network must have compatible IP addresses.

A recessed switch lets you reset the network settings to factory default. To reset, turn the MixRack off, insert a pointed object to press and hold the switch whilst turning the MixRack back on. Hold the switch in for at least 15 seconds.

gigaACE link: This is a MixRack to Surface link over Gigabit Ethernet (IEEE 802.3 Layer 2 compliant). A single Cat5e (or higher) cable carries bidirectional 96kHz audio and control. Use two cables for redundancy – the system will seamlessly switch cable in case of failures, without any audio dropout.

DX links: These are dual redundant EtherCon ports for connection of up to 4 DX expanders over Fast Ethernet (IEEE 802.3 Layer 2 compliant). A single Cat5e (or higher) cable carries 32×32 channels of 96kHz audio and control. Use the I/O screen to patch signals from or to the DX expanders.

ME: This is a dedicated EtherCon port for the Allen & Heath ME personal mixing system. A single Cat5e (or higher) carries 40 channels of 48kHz audio, channel names and stereo links. Connect a ME-1 mixer for daisy chaining or ME-U hub for power and audio distribution. Use the I/O screen to patch signals to the ME system.

Word Clock I/O: These are BNC connectors for syncing from an external audio clock or providing a clock to other devices. Use the MixRack / Audio / Audio Sync screen to select the clock source.

Audio Sync Lock: This indicator shows that the audio is sync locked to a valid clock source. If this does not light up, check that the correct clock source is selected in the MixRack / Audio / Audio Sync screen.

This is a standard 1/4″ jack socket and level control for the built-in headphone amplifier. The output follows the PAFL selection.

dLive MixRacks ship with one PSU fitted. A second PSU can be fitted for redundancy (part number MPS-16). The power supply is hot swappable.

1. Loosen the 4 captive thumb screws securing the blank panel. On early dLive units, remove the 4 screws securing the blank panel using a star Torx T8 screwdriver.

2. Slide the PSU into the slot.

3. Tighten the 4 captive thumb screws.

The MixRack will automatically switch between the supplies without interruption to the audio should one fail. Heed the safety warnings printed on the panel.

A plastic P-clip cable clamp is provided to secure the mains cable. Slot the cable in or lock it in place using a star Torx T20 screwdriver to refit the clamp around the cable.

Fan: An ultra-quiet fan. Make sure the ventilation opening is not obstructed.

Kensington Lock: A slot for fitting standard Kensington anti-theft security devices.

Status indicators: Power ON indicators for the 2 power supplies. The Ready indicator lights up when the output sockets are ready to pass audio after power up.

Power Up: Switch on the MixRack. It takes around 15s for the mix engine to start passing audio. You should hear the relays click as they connect the outputs once the boot-up is completed. The Ready indicator on the front panel will light up at this point.

Surface Connection: Plug a touring grade CAT5e (or higher specification) cable up to 100m long between the dLive Surface and MixRack gigaACE ports. Use two cables for redundancy if required. Switch on the Surface. The gigaACE Lnk/Err indicators flash at a steady rate when the link is established. The red error indicator lights if a communication error is detected. Check that the cables are correctly plugged in and are not faulty. It takes around 30s for the Surface to take control and the touchscreen to be responsive.

Expander Connection: Plug a touring grade CAT5e (or higher specification) cable up to 100m long between the DX Expander and MixRack DX ports. Use two cables for redundancy if required. Switch on the DX Expander. The DX port Lnk/Err indicators flash at a steady rate when the link is established. The red error indicator lights if a communication error is detected. Check that the cables are correctly plugged in and are not faulty.

ME System Connection: Plug a touring grade CAT5e (or higher specification) cable up to 100m long between the MixRack ME port and the ME-1 or ME-U.

Connect a laptop, router or access point to either of the Network ports to use with dLive Editor or iOS apps. Read the Release Notes and Help Files accompanying the software or apps for further information.

dLive communicates over TCP/IP. All devices on the network including the MixRack and Surface must have compatible IP addresses. Factory defaults are:

MixRack: 192.168.1.70

Surface: 192.168.1.71

Subnet Mask: 255.255.255.0

Gateway: 192.168.1.254

For direct, wired laptop connections, set your laptop to a static, compatible IP address, for example 192.168.1.10.

For wireless connections, set your router / access point to a compatible IP address, for example 192.168.1.254, and its DHCP range to a compatible range of addresses, for example 192.168.1.100 to 192.168.1.200. Set any wireless laptop or mobile device to DHCP / ‘obtain an IP address automatically’.
