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. The following diagrams show “bridged” connections from the amplifier.

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.
