C-700u Exquisite sound, flagship pedigree. A dream come true. The C-700u control amplifier is our new middle of the range model that inherits some of our magnificent innovations, seen in our high end model, the C-900u, including our latest ODNF version 4.0 circuit, with significantly improved distortion characteristics and signal to noise performance and our new LECUA 1000, a computerized attenuator directly connected to the amplifier circuit, which enables smooth volume changes without any deterioration of sound quality. We are pursuing the concept of a simple and high quality control amplifier, exclusively designed for line level signals. What is more, this unit is also multifunctional, the loudness function interacting with the volume and tone controls, external pre-input connectivity and a fluorescent display with zoom and dimmer controls. Features like these make the C-700u suitable for the control center of your system, a new-generation of control amplifier, displaying performance consistent with high level functionality.  Gallery  Spec  Download New LECUA 1000 and ODNF version 4.0 Just like our top of the range model, the C-900u, the C-700u features the new LECUA 1000 high precision electronically controlled attenuator in an unbalanced configuration. An accurate volume adjustment mechanism is fundamental to the operation of a control amplifier. The LECUA* system is extremely resistant to external vibration and changes in sound quality over the volume control range, as well as being an extremely durable design. The LECUA circuit uses stepped fixed resistance and increasing the number of steps from 72 to 88 allows more delicate volume control adjustments from 0dB to 87dB with no deterioration of sound quality. This circuit also accurately handles any left and right balance adjustments. Our latest negative feedback circuit, ODNF** version 4.0, achieves even higher performance by being quadruple paralleled in the first main amplifier stage, triple paralleled in the first error detection stage and featuring a Darlington connected second stage. Only the distorted components of the audio signal are fed back to the amplification circuit to optimize the negative feedback effect. Increased primary slew rate and ultra-wide bandwidth contribute to an extremely low level of distortion, especially in the high frequency range. An improved signal to noise ratio allows the full expression of delicate musical pieces where the amount of feedback should be minimal.* LECUA stands for "LUXMAN Electrically Controlled Ultimate Attenuator".** ODNF stands for "Only Distortion Negative Feedback". Large capacity power supply In order to embody the philosophy of "Power Amplifier Driver", meaning a component which powerfully drives a power amplifier connected in the next stage, the C-700u has a large capacity power supply featuring an OI-type power transformer and is regulated by two 3,300μF blocking capacitors. This circuit creates a firm power base to support the sound quality of the C-700u. Zoom display mode The highly visible fluorescent display is equipped with a dimmer and has a four level zoom mode, adjusted via the remote control. The two part display usually displays the input source and volume level and is also eye-friendly and clearly visible from the listening position. External pre-input terminals and balanced phase selection The C-700u is equipped with unbalanced external pre-amp input terminals to which an external pre-amplifier in your AV system may be connected. The balanced inputs have the option of phase switching (pin no.3 HOT to pin no.2 HOT) which can be adjusteded and memorized for each balanced input. This is useful for connecting to units made by other manufacturers. New 3D layout in the pre-amp section The new LECUA 1000 system uses a 3D component layout to both minimize the signal route and improve it's efficiency. The ultimate solution for a high class control amplifier is realized by the direct connection between the attenuator circuit and the amplification circuit, eliminating the concept of independent, individual circuit blocks. Chassis and isolator legs A loopless chassis structure has been used for the enclosure to eliminate increased ground impedance and the effects generated by electrical or magnetic fields. Cast-iron isolator legs prevent resonance thanks to the characteristics of their metallic structure, the density gradient decreases from the center to the periphery of each leg. The legs also eliminate adverse effects caused by vibration and effects from the power transformer or the supporting surface. Specially selected custom parts The C-700u features original custom made components, such as resistors, capacitors and even the unit's entire wiring, designed or selected as a result of LUXMAN's advanced experience and sensibility, accumulated over a long history of designing audio products. We consider sound quality as our first priority. The selected components have contributed to the realization of rich tone that LUXMAN has constantly pursued. Comfortable remote control operation The slim aluminum remote control feels comfortable in the hand and allows users to operate a wide variety of the C-700u's functions, such as input selection, volume adjustment, display zoom and dimming, loudness and more from the listening position.
