1RCA Input and Pass-Thru Output - These RCA jacks allow for a normal Left and Right channel signal input. Simply connect to the source unit using RCA type audio cables, keeping them away from power wiring wherever possible. On the 4 channel amplifiers (D3 500.4) “Front” and “Rear” input jacks are present as well as a “Pass-Thru” output allows the signal to pass on to other amplifiers. The Pass-Thru output is unaffected by the onboard crossover.

2Input Gain Adjustment - This control matches the preamp stage of the DAT amplifier to your source unit. This is NOT a volume control. The range is between 150mV and 4V.

3Crossover Adjustment- Use this adjustment to select the crossover point. Remember that your choice will be directed to High Pass or Low Pass depending upon the position of the adjacent switch. The range of adjustment is limited between 30-500 Hz (D3 400.2), 40-400 Hz (D3 500.4) and 30-250Hz(D3 600.1) , 50-250Hz (D3 1000.1)

4Crossover Selection Switch - This switch allows you to select the crossover. Use High Pass for midrange or high frequency speakers. Use Low Pass for subwoofers. In the OFF position, the crossover adjustment knob has no effect. The D3 600.1 and the D3 1000.1 are only available as Low Pass.

5Sub-Sonic Adjustment - This control allows you to adjust the "pass-band" for a true 3 way speaker system. This helps solve "standing wave" problems in-car (boomy bass), AND protects midrange/mid-bass drivers at the same time. The D3 400.2 is 10 - 100 Hz, D3 600.1 is 15-75Hz and the D3 1000.1 has an adjustment from 15-40Hz

6Phase Adjustment (D3 600.1/D3 1000.1 Only) - This control allows you to adjust the "phase" so as to align the subwoofer in "time" to the mids and tweeters. 0 to 180 degrees of adjustment capability. This is EXTREMLY useful to get the best and MOST bass out of your system.

7Bass Boost - This control adds 0 to +12dB of boost at 50Hz. Be cautious when adding boost to some subwoofer systems as they may not be able to handle the additional low frequency boost. In the OFF position, no bass boost is added.

8Remote Level Adjustment (D3 600.1/D3 1000.1 Only) - This port is for the remote level control (included). The control is intended to allow the user to control the level of gain up to the maximum adjustment level set on the amplifier. The control does not add additional boost, it only attenuates the setting that is fixed at the amplifier’s control panel.

9Status LED’s - These lights indicate when the amplifier is powered up normally and when there is a protection fault. See the “Troubleshooting” section for details on what these useful indicators can tell you if there’s a problem.

10

Power Input Connections - These connections are for input power, chassis ground, and remote turn-on. Use a minimum of 4 gauge

wiring for power and ground connections. The terminals will handle up to 4 gauge wiring with no problem whatsoever. Be sure

 

any wiring that passes through metal has a grommet!

11

Power Fuses - Standard automotive type ATC/ATO fuses are used on DAT D3 Series Amplifiers. Always replace with the correct

fuse size. Never insert fuses of higher values. Doing so will void the warranty of your DAT amplifier. Also include a main fuse at

 

the connection to the vehicle battery within 18 inches (45.7 mm) of the positive battery post. It is also important to upgrade the

 

connection between the negative battery post and the chassis of the vehicle. This greatly reduces possibilities of weak electrical

 

“links” in the circuit.

12

Speaker Output Terminals - Connect your speakers to these terminals. Stereo connections are connected as labeled. Bridged

connections use the LEFT + and RIGHT - as the two connections. The 2 and 4 channel amplifiers will perform into 2 Ohm stereo loads

or 4 Ohm bridged loads. DO NOT run 2 Ohm bridged loads on these amplifiers! The D3 600.1 and the D3 1000.1 are the only amplifier's in the D3 Series capable of less than a 2 Ohm load (D3 600.1/D3 1000.1 are capable of driving a load as low as 1 Ohm.)
