3 OPERATIONS

3.1 DYNAMIC MICROPHONES

Dynamic microphones are characterized by lower output levels. Hence, more gain is needed to amplify a dynamic microphone to operating level. Occasionally it is necessary to add the -20dB pad to the microphone to avoid distortion (e.g. when recording percussion).

Do not use phantom power when using dynamic microphones.

3.2 PHANTOM POWERED MICROPHONES

Phantom powered microphones such as condenser and some ribbon micro- phones require external power to preamplify the microphone acoustic pickup. These microphones typically have much higher output than dynamic micro- phones. Hence the -20dB pad is almost always necessary when close micing to avoid clipping the amplifier.

3.3 LINE LEVEL INPUTS

The 1⁄4” inputs on the DigiMAX LT are designed for use with line level or low impedance inputs not instrument level inputs. These inputs will work for line level devices such as keyboards, samplers, drum machines, CD players, etc.

3.4 APPLICATION GUIDE

Outboard Dynamics Processing Example

The DigiMAX LT has an insert on every channel that allows you to insert your own dynamics processor, such as a compressor, EQ, limiter, or etc. To do this, all you need is your dynamics processor and a TRS insert cable. This cable is Y- shaped, has a single TRS 1⁄4” jack on one end and two 1⁄4” TS jacks on the other end. The single end will look like a stereo 1⁄4” connector jack. This end of the cable plugs into the insert jack on the back of the DigiMAX LT. The other ends of the cable plug into the input and output of the outboard unit. If the outboard unit does not work immediately, you may want to try swapping the jacks that are plugged into the input and output of the outboard unit.

Insert Jacks As Analog Outputs Example 1

You may have noticed by now that the DigiMAX LT does not have a standard analog output. In the event that you want to have analog outputs as well as the lightpipe output, you can use the inserts as analog outputs. To do this, all you need is a 1⁄4” TS cable. Plug the cable in until you feel

FAQ

What are dynamic microphones?

Dynamic microphones are characterized by lower output levels, requiring more gain to amplify to operating level. It may be necessary to add a -20dB pad to avoid distortion, especially when recording percussion. Do not use phantom power with dynamic microphones.

What are phantom powered microphones?

Phantom powered microphones, such as condenser and some ribbon microphones, require external power for preamplification. They have much higher output than dynamic microphones, necessitating the use of a -20dB pad for close micing to avoid clipping the amplifier.

How to use outboard dynamics processing with DigiMAX LT?

The DigiMAX LT has an insert on every channel for inserting a dynamics processor, such as a compressor, EQ, or limiter. Use a TRS insert cable to connect the outboard unit to the insert jack on the amplifier.
