|The OptiDrive 100.4 is a four-channel amp rated at 50 watts x 4 or 180 watts x 2 into 4 ohms. Features include gold-plated connections, internal crossovers with variable cutoff frequency, and selectable post crossover line outputs. The amps beefy brushed anodized aluminum heatsink features tasteful black and gold accents.
It looks like Lanzars making a run at the hardcore competition scene. They seem to have been around forever, but their most recent offerings have been aimed more toward the consumer end of the market. This new batch of Opti-Drive amplifiers will help Lanzar make its mark on the
competition scene and it looks like theyll be doing it with power, grace, and style to boot.
The 100.4 has more than a few specs to brag about from a competition standpoint. Signal-to-noise measured an impressive 111 dB and turn on/off noises are in the 4.5 dB SPL range. The 100.4 also offers a wide range of input sensitivity, and power ratings are quite conservative with a bonus of about 30 percent when driving 4-ohm loads. Overall, this unit is quite impressive; we wont be surprised to find a few of these in the competition lanes when next season really gets rolling.
Connections & Adjustments
Connections to the 100.4 include RCA inputs, RCA line level outputs, and captive-style screw terminal blocks for all power and speaker connections. The power and ground connections accept up to #4 AWG and the speaker terminals will comfortably handle #12 AWG. All adjustments to the 100.4 control a pair of channels and include input sensitivity, line output configuration, crossover mode select, and separate cutoff frequency adjustments for the high- and low-pass sections.
Installing the 100.4 shouldnt be a major hassle its probably small enough for under-seat mounting in larger cars, and we didnt notice any potential grounding problems. The amps front end provides a fair amount of processing ability and seems to have been designed with the idea of multi-amp systems in mind. The manual included with this unit covers
the five amps inthe OptiDrive line-up, but does so reasonably well.It includes large, easy-to-read wiring diagrams for nine potential system configurations, installation and operation instructions, and a modest troubleshooting guide.
