Model No.: SVX-558D

Using this Digi Q is probably going to be the easiest thing to use in your car.

You can control all the functions of this unit from only one knob of the unit.

This one knob can be pressed or rotated to make raise, lower, select and

move from one function to another.

In idol mode, the unit will display the status of your battery voltage. You can

either press the knob to gain access to the functions, or turn the knob in the

dirrection you want to adjust the volume of the system.

ln idol mode oress the knob toswitch between all the functions, like inputs,

EQ settings, volume, sub-control, etc. Once you reach a point you want to

adjust you turn the knob to select your prefered setting.

So what type of controls do you have on this unit, there are master volume

control, fader, sub-woofer crossover and level, 7 EQ bands, input selection

and frequency counter.

This new breed of equalizer has a ton of possibilities. Use your imagination

to set it the best scenario.

With multi inputs, you can select an audio source from all types of devices

With a little work, you can use the AUX/CD CHANGER input to allow you to

listen to almost any portable MP3 Player, or a second CD/DVD player inthe

car.

Using the volume control in the EQ over the volume control of the main

source unit is more practical. Using the main source unit leaves the output

of the EQ at a high tilt which can cause excessive noise or hiss when you

lower the level of the source unit. You can avoid all that by using the volume

of the EQ instead, besides the EQ offers better S/N and seperation than the

source unit (in most cases).

When applying a second source to the EQ, make sure to level match the two,

this way when you switch from one to the other you won’t have unexpected

clip or the need to change the master volume to accomodate the auxilary

source signal. You can do this with the controls in the EQ. you start by press-

ing the knob of the Digi Q until it reaches the control point for the AUX/CD

CHANGER input and make your adjustments accordingly.
