    Thank you for choosing a new Diamond Audio amplifier. Diamond Audio amplifiers are engineered and produced with the highest quality materi- als and incorporate the latest technology. We think you will find your new Diamond Audio amplifier meets or exceeds your expectations and provides excellent value.
  • Page 3 Frequency Response: 20Hz to 20KHz +/-1 dB D300.2 Signal to Noise Ratio: >90dBA (20 to 20kHz) Channel Separation 60dB 2-Channel Amplifier THD+N(Total Harmonic Distortion + Noise) <0.02%(Output-1W 4 Ohms) RCA Input Sensitivity: 150mV to 5V Min to Max Voltage requirements 9V to 15.5V DC 300 Watts RMS Output Power High/Low Pass Crossover:...
  • Page 4: Connections And Controls

    2 and 4 Channel Models Connections and Controls This section describes all of the terminals and adjustments. 4 gauge power and ground wire is recommended for all models.
  • Page 5 Mono Models Connections and Controls This section describes all of the terminals and adjustments. 4 gauge power and ground wire is recommended for all models.
  • Page 6 “Front” and “Rear” input jacks are present. The“Pass-Thru” output allows the signal to pass on to other amplifiers. The Pass-Thru output is unaffected by the onboard crossover. Input Gain Adjustment - This control matches the preamp stage of the Diamond amplifier to your source unit. This is NOT a volume control. The range is between 150mV and 5V.
  • Page 7 Using a Single Bass Knob to Control Multiple Amplifiers (D600.1, D1000.1) Your new Diamond Audio amplifiers have the unique ability to use one remote level control to control multiple amplifiers. You must be using at least two D600.1's or two D1000.1's.

    Adequate Length—Remote Turn-on Wire (minimum 22 gauge) The Importance of Pre-Planning This section focuses on some of the considerations for installing your new Diamond Audio amplifier. Pre-planning your audio system layout and best wiring routes will save installation time. When decid- ing on the layout of your new components, be sure that each component will be easily accessible for making adjustments.
  • Page 10: Mounting Locations

    Mounting Locations Engine Compartment Never mount this unit in the engine compartment. Mounting the unit in the engine compartment will void your warranty. Trunk Mounting Mounting the amplifier vertically will provide adequate cooling of the amplifier. If you will be mounting it to an existing panel, be sure it’s not prone to excessive vibration (such as mounting to the back of a subwoofer enclosure).
  • Page 11 Trim the power cable within 18 inches (45.7mm) of the positive battery post and splice in a in-line fuse holder. DO NOT install the fuse at this time. Strip 1/2 inch (12.7mm) from the battery end of the power cable and crimp a large ring terminal to the cable.
  • Page 12 RCA Inputs Connecting Speakers To Mono Block Amplifiers All Diamond mono block amplifiers come with two positive speaker terminals and two negative speaker terminals. This makes it easier to connect multiple woofers to one amplifier. Inside of the amplifier the two positive terminals are connected in parallel and the two negative terminals are connected in parallel.
  • Page 13 Connecting Multiple Speakers If you must connect more than one speaker per channel, there are two methods in which to do so: Series or Parallel. Parallel connections are harder on the amplifier than series connections, as the total impedance is lower compared to driving a single speaker, and the amplifier must produce more current to drive them.
  • Page 14 For more wiring options, see the Support section at www.diamondaudio.com Installing the Remote Level Controller The D400.1, D600.1, & D1000.1 come packaged with a remote level control. This allows you to control the level by attenuating the amplitude or increasing (up to the maximum set-point) of the amplifier’s input gain control.
  • Page 15: Troubleshooting

    Adjustment of Built-In Crossover (All Models) Placing the switch in the FULL position sets the amplifier to Full Range. This setting allows ALL frequencies to pass to the speakers. (Not available on D600.1, & D1000.1). Placing the switch in the HP or LP position activates the crossover. Placing the switch in the HP position sets the amplifier to the High Pass mode, enabling frequencies above the cutoff point to pass.
