it ‘click’ once. The cable will appear to be ‘half plugged in’. Using the insert in

this fashion will not break the signal chain and will allow the lightpipe output to

function correctly.

Insert Jack As Analog Outputs Example 2

In the event that you do not need the lightpipe output, you can use the inserts

as analog outputs. To do this, all you need is a TRS insert cable. This cable is

Y-shaped, has a single TRS ” jack on one end and two ” TS jacks on the

other end. The single end will look like a stereo ” connector. This end of the

cable plugs into the insert jack above the input on the back of the DigiMAX LT.

You would use the SEND end of the cable as the output cable.

By using the insert as an analog output with an insert cable, you will not be

able to pass a signal through to the adat™ (lightpipe) output. The reason for

this is that a signal is sent to a piece of outboard gear from the insert jack and

then returned to the insert after being processed. So, in other words you are

breaking the signal chain by using the send and not the return.

Using The DigiMAX LT As A Front End For Digital Recording Systems

The DigiMAX LT is the perfect front end for a digital recording system. The pre-

amps on the unit allow you to boost the signal going to your recorder without

adding extra, unwanted, noise. All digital recorders require that word clock be

transmitted with a digital audio signal to ensure sample accuracy and syn-

chronization. Word clock scans incoming information and automatically synchs

to the necessary sample rate. In other words, word clock ensures that the

recorder and the sending device (in this case the DigiMAX LT) send and receive

digital audio at the same rate. If there is no word clock synch then you will hear

pops, clicks, or weird digital dropout noise. Word clock can either be transmit-

ted through the lightpipe cable (ber-optic) or by BNC cable. If the DigiMAX

LT is the master (sending word clock out to the recorder), then there are two

possible connection scenarios. Both cases require that the EXT CLOCK button

on the front of the unit be depressed (not pushed in) and that the appropriate

sample rate be selected by using the SAMPLE RATE button on the front of the

unit. The rst case in which the DigiMAX LT is the master would require that the

word clock output of the DigiMAX LT be connected to the word clock input of the

recorder by BNC cable. The second case in which the DigiMAX LT is the master

would require that the recorder receive word clock from the adat™ lightpipe

ber-optic cable. This second scenario requires that the digital recorder be set

to receive word clock via lightpipe. This is often done by either hitting a button
