A150.4D

4-Channel High Fidelity Class-D Amplier

A600.1D

1-Channel High Fidelity Class-D Amplier

A150.4D

High Fidelity Class-D Amplifier

Controls and Functions (150.4D):

Turn On Mode:

Signal: Senses audio signal on the speaker

level inputs (>800mVp) and on the line lev-

el inputs (>45mVp) to turn on the amplier.

There will be a short delay in turn-off to

accommodate silence between tracks.

Offset: Senses the 6V BTL reference when

the speaker level inputs are connected to

the outputs of a BTL amplier or head unit.

Rem: Senses the remote turn on output of

the head unit or to the car’s ACC circuit.

Crossover Channels 1 and 2 (3 and 4)

Filter Type:

HP: Only the low frequencies below the

High Pass lter frequency selection will be

removed from the signal.

BP: Low frequencies below the High

Pass lter frequency selection and high

frequencies above the Low Pass lter

frequency selection will be removed from

the signal.

None: No high pass or low pass lter will be

applied. All frequencies will pass.

Low Pass Control Group:

50Hz-500Hz: Adjusts the low pass lter fre-

quency to any frequency between 50Hz

and 500Hz. High frequencies above this

selection will be removed.

X1-X10: When this switch is set to X1, the

lter frequency range is 50Hz-500Hz. When

this switch is set to X10, the lter frequency

range is set to 500Hz-5000Hz

High Pass Control Group

20Hz-400Hz: Adjusts the high pass lter fre-

quency to any frequency between 20Hz

and 400Hz. Low frequencies below this

selection will be removed.

X1-X10: When this switch is set to X1, the

lter frequency range is 20Hz-400Hz. When

this switch is set to X10, the lter frequency

range is 200Hz-4000Hz.

Input Cong:

3Ch: Input 1 sends signal to output chan-

nels 1, 3 and 4. Input 2 sends signal to

output 2, 3 and 4. Inputs 3 and 4 are not

used. Outputs 3 and 4 will output the sum

of inputs 1 and 2 (1+2). Use when output

channels 3 and 4 will be bridged to drive a

subwoofer with two input connections.

2Ch: Input 1 sends signal to outputs 1 and

3. Input 2 sends signal to outputs 2 and 4.

Inputs 3 and 4 are not used.

4Ch: Each input sends signal to its corre-

sponding ouput (1-1, 2-2, 3-3, and 4-4).

Level:

Adjusts the voltage sensitivity (level) of

each pair of inputs. For line level input sen-

sitivity, Min is 10Vp and Max is 500mVp.

DO NOT APPLY MORE THAN 30Vp TO THE

SPEAKER LEVEL INPUT CONNECTIONS OR

THE UNIT WILL BE DAMAGED!

Power: This LED will light green to indicate

that the unit is on.

Protect: This LED will light red to indicate

a fault and the amplier will produce no

sound. Faults include: power supply input

voltage is too high or too low, output

connection is short, amplier heat sink

temperature is too high.

Notes about crossover settings: When

using any pair of amplier channels in

BP (bandpass) mode, the HP (high pass)

frequency control MUST be set to a LOWER

frequency than the LP (low pass) frequen-

cy control. For example, if channels 3 and

4 will drive midrange speakers only, the LP

frequency control might be set to 3500Hz

and the HP frequency control might be

set to 100Hz. The signal sent to the speaker

will be frequencies BETWEEN 100Hz and

3000Hz. If there is no ouput from a pair of

channels, check these settings carefully.

Controls and Functions (A600.1D):

The Turn-On Mode and Level control

for the A600.1D operate exactly like the

controls on the A150.4D. The Power and

Protect LED functions are also the same

as the 150.4D. Because the A600.1D is a

single channel amplier designed to drive

low frequency speakers or subwoofers, the

crossover controls are somewhat different

and are explained below.

High Pass 5Hz-40Hz: Adjusts the high pass

lter frequency to any frequency between

5Hz and 40Hz. Low frequencies below this

selection will be removed. For subwoofers

in vented boxes, set this control about a

half an octave below the frequency at

which the enclosure is tuned to prevent

too much excursion from damaging the

speaker. This is also useful for innite bafe

subwoofers. If your system doesn’t require

a high pass lter for the subwoofer, set this

control to its minimum setting (5Hz).

Low Pass 50Hz-500Hz: Adjusts the low pass

lter frequency to any frequency between

50Hz and 500Hz. High frequencies above

this selection will be removed.

Phase 0°-180°: Adjusts the phase of the

output at the crossover frequency be-

tween 0 degrees and 180 degrees. Use

this control to match the phase of the

subwoofer with that of the front speakers

to help blend the sound of the subwoofer

into the sound of the front speakers.

45Hz 0dB-15dB: Adjusts the amount of

45Hz in the output between 0dB and

15dB. Adjust this as you wish but be careful

because too much bass boost can cause

distortion at high output when the am-

plier runs out of available power at high

volume. Each 3dB of boost requires double

the power of the unboosted frequencies.

3dB requires twice the power. 6dB requires

four times the power. 9dB requires eight

times the power. 12dB requires sixteen

times the power and 15dB requires 32

times the power sent to the unboosted

frequencies.

Remote Level Control (optional): This

control, if installed, allows the level of the

output of this amplier to be controlled

from the front of the car. The RLC will vary

the output level of the amplier between

off (fully counter-clockwise) and the level

control setting selected with the level con-

trol on the amplier (above).

Using These Ampliers With a DSP: When

using these ampliers with a DSP, you

can (and should) defeat the A150.4D’s

on-board crossovers by selecting “None”

with the Filter Type switch if the lter will be

implemented in the DSP. When using the

A600.1D with a DSP, adjust the Low Pass

lter to its highest frequency (500Hz) and

the High Pass lter to its lowest frequency

(5Hz) if you will implement the high pass

lter in the DSP. You can also use the high

pass lter in the amplier to protect your

subwoofer from over excursion if your DSP

doesn’t include a high pass lter for the

subwoofer.

When Driving Tweeters Separately in an

Active System: Set the high pass lter

frequency about an octave above the

tweeter’s free air resonance (Fs). An oc-

tave is a doubling or halving of frequency.

So, if your tweeter’s Fs is 1.5kHz, set the

crossover at 3kHz.

Use a protection device to save your

tweeters in case of a mishap. A capacitor

and a resistor work well. Choose the value

of the capacitor to provide a -3dB point

about an octave below your crossover.

The values below are suitable for all Au-

diofrog tweeters.
