4. GETTING STARTED

Connected ahead of the line inputs of a mixing desk/recording device:

Because of the various functions of the equipment, such as a mic preamp, line level or

instrument front end, you can connect the output(s) of the equipment directly to the line

input of your console, recorder or sound card. We do not suggest you to connect line level

outputs to microphone inputs, because this may affect the quality of signal and may cause

level overload on the mixer. The equipment has balanced line outputs for professional

sound quality, but can connect to an unbalanced line input easily. Once the outputs are

connected, feed your chosen source into the relevant input of the equipment simply (mic

will connect to the XLR input on rear panel, line level signals such as mixer or tape

machine outputs will connect to the equipment line inputs, and keyboards, guitars and

basses will use the equipment front panel instrument inputs).

The input selector switch is at the top left of the equipment front panel. Through it, you

can select the relevant input source. 'Mic 48V' is necessary for condenser type

microphones that require 48V phantom power. When using dynamic and ribbon type

microphones the 'Mic' position only should be selected. Take care not to select the Mic

48V position when using such microphones as the 48 Volt feed could harm the

microphone probably. The equipment will route the microphone signal to both the left and

right output channels. If a mono instrument (or mono line level source) is connected to the

left input (marked 1/mono) the signal will be routed to both left and right channels.

Connecting a mono signal to the right input will send the signal to the right hand output

only. Nowadays, it is a common technique recording direct to the multitrack recorder (thus

bypassing the console), it can keep the signal path shorter, and get the highest quality.
