Connections

Wiring conventions

The D-MIX500 uses various different types of audio connector: 3-pin XLR , 1⁄4" 3-pole jacks and RCA phono connectors. This section describes how to connect external equipment to the console. Correctly-made cables of the proper type will ensure peak performance from your mixer.

Input

The mic input accepts XLR-type connectors and is designed to suit a wide range of BALANCED or UNBALANCED low-level signals. Professional dynamic, condenser or ribbon mics are best because these will be LOW IMPEDANCE. While you can use low-cost HIGH IMPEDANCE mics, you do not get the same degree of immunity to interference on the microphone cable and as a result the level of background noise may be higher. If you turn the PHANTOM POWER on, the socket provides a suitable powering voltage for condenser mics.

2. Hot(+ve)						DO NOT use unbalanced sources with the phantom power switched on. The voltage
						on pins 2 & 3 of the XLR may cause serious damage.

			Input			Jack Sockets
						The 1/4" input jacks on this console fall into one of two categories: balanced inputs
						and unbalanced inputs. The diagram on the left shows the connections for both types.
						The following input jack sockets are balanced:
Balanced					Unbalanced AV1 Left, AV1 Right, Input A, Input B, AV2 Left, AV2 Right, Main Output Insert
Hot (+ve)					Signal	Return Left and Main Output Insert Return Right.
Cold (-ve)					Gnd/Screen These inputs accept 3-pole 1/4" "A" gauge (TRS) jacks, or 2-pole mono jacks which
Gnd/Screen					Gnd/Screen will automatically ground the "cold" input.
		Tip				These inputs are BALANCED for low noise and immunity from interference, but you
						can use UNBALANCED sources by wiring up the jacks as shown left, although you
	Ring
					Sleeve	should then keep the cable lengths as short as possible to minimise interference pick-up
						on the cable. Note that the ring must be grounded (by linking it to the sleeve ) if the
						source is unbalanced.

The FX Insert Return jack socket is unbalanced. It will accept a 3-pole 1/4" "A" gauge (TRS) jack, or a 2-pole mono jack. It you use a 3-pole jack, the ring must be linked to the sleeve.
