Installing the Remote Level Controller

The HA 750.1 comes 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. This control does not add additional gain, it simply allows you to control the level to suit your tastes.

1)Locate a position in the front of the vehicle where this will be easy to reach. Common locations are on, in, or under the dash, in the center console, or in the glove box.

2)To mount the unit, attach the bracket using the supplied hardware to your chosen loca- tion.

3)Route the telephone style data cable back to the amplifier location and connect into the remote level port. Test to make sure the operation is functioning.

Perform a final check of the completed system wiring to ensure that all connections are accurate. Check all power and ground connections for frayed wires and loose connections which could cause problems. Install in-line fuse near battery connection at this time. Prepare to make some adjustments to fine tune your audio system for optimum performance.

Adjustment of Input Gain

To adjust the gain setting, turn the amplifier gains all the way down (counterclockwise). Turn the source unit volume up until distortion is audible and then turn it down a bit until the distortion is inaudible. This will be NEARLY full volume on most source units, perhaps one or two “clicks” down from maximum volume. Next, increase the amplifier gain setting until adequate volume is achieved.

NOTE: Ideal signal to noise and dynamic range are achieved with the gain at minimum. Most users find adequate gain and volume is achieved at about halfway in the adjustment range. Avoid setting the amplifier gain very high as noise and distortion will increase signifcantly.

HA 750.1, HA 700.2, HA 700.4 specifications

Diamond Audio Technology has established itself as a key player in the high-performance audio industry, particularly known for its innovative amplifiers. The Diamond Audio HA series, encompassing the HA 700.4, HA 750.1, and HA 700.2 models, is designed for audiophiles who demand top-notch sound quality and reliability.

The HA 700.4 is a robust four-channel amplifier that delivers an impressive 100 watts RMS per channel at 4 ohms, while producing an astonishing 200 watts RMS per channel at 2 ohms. This amplifier employs advanced Class A/B circuitry, ensuring that audio reproduction is both powerful and crystal clear. It is equipped with high-level inputs, making it versatile enough to integrate with factory-installed audio systems. The HA 700.4 features a variable crossover, which allows users to tailor the output to suit specific audio preferences and achieve a balanced soundscape.

Next in the series, we have the HA 750.1, a mono amplifier capable of producing up to 750 watts RMS at 1 ohm. This model is designed for enthusiasts seeking strong bass performance. Its powerful output is complemented by a low-pass filter, enabling users to optimize their subwoofer performance. The HA 750.1 utilizes a high-performance MOSFET power supply, which ensures efficient power delivery and minimizes distortion, resulting in deep, rich bass tones.

Completing the lineup is the HA 700.2, a versatile two-channel amplifier that delivers 110 watts RMS per channel at 4 ohms and 220 watts RMS at 2 ohms. Ideal for driving component speakers or smaller subwoofers, the HA 700.2 features similar Class A/B technology as its counterparts. Its compact design is perfect for installation in tighter spaces while maintaining thermal efficiency through built-in heat sinks.

All three amplifiers are designed with durability in mind, featuring heavy-duty aluminum chassis that resist corrosion and provide excellent heat dissipation. The inclusion of adjustable gain control and built-in protection circuits further ensures reliability and longevity under various operating conditions.

In summary, the Diamond Audio Technology HA 700.4, HA 750.1, and HA 700.2 amplifiers boast state-of-the-art technologies, robust outputs, and user-friendly features that cater to serious music lovers. Whether enhancing high-frequency details or delivering deep bass, these amplifiers provide an unparalleled audio experience, making them a worthy addition to any sound system.
