TAD LABS INTRODUCES THE REFERENCE SERIES TAD-C700 PREAMPLIFIER

Technical Audio Devices Laboratories has announced the TAD-C700 preamplifier as the newest addition to its Reference Series of HiFi audio components.

The new TAD-C700 Preamplifier will officially be unveiled at High End Munich 2024.

TAD LABS TAD-C700 PREAMPLIFIER

The new TAD-C700 incorporates a slew of technical refinements and enhancements to achieve a “new level of performance”, replacing the TAD-C600, TAD’s previous top-of-the-line preamplifier released in 2011.

TAD-C700 PREAMPLIFICATION CIRCUIT

The TAD-C700 has a high-performance, single-stage current-feedback amplifier in its flat amplifier section, using minimal of amplifying elements. A dedicated output amplifier circuit provided to each of the two line outputs prevents signal branching and interference from connected equipment,

FULLY BALANCED CIRCUITRY AND DUAL-MONO CONSTRUCTION DESIGN

The C700’s fully balanced circuit topology amplifies positive and negative signal waveforms individually from input to output in order to suppress even the smallest amplification errors between positive and negative signals, as well as between right and left channels. The wire length and dressing are identical between positive and negative signal paths and between both channels, to achieve an ideal signal path from input to output. Furthermore, the dual-mono construction design of circuitry achieves maximum symmetry to provide identical amplification, both electrically and mechanically, to positive and negative signals and to both channels.

OUTBOARD POWER-SUPPLY UNIT

The C700’s power-supply unit is physically separated from the main amplifier unit. This design is designed to prevent vibration and magnetic flux leakage from the transformer, thus preventing any adverse effects to the mechanical sections and audio circuits of the main unit. To increase the purity of power supply, the internal coil of the transformer is directly connected to the power supply circuit, minimizing the contact points with leading wires. The terminals for directly connected coils, mounting terminals for motherboards, and clamping screws are all made of oxygen-free copper coated with nonmagnetic materials to eliminate even the slightest magnetic distortions. A powerful toroidal transformer with a 400 VA power rating powers the audio circuit to achieve greater signal transition performance. The entire power supply is housed in a rigid cast-aluminium monocoque chassis to suppress unwanted vibrations.

TAD-C700 PREAMPLIFIER VIBRATION-SUPPRESSING DESIGN

The C700’s main amplifier circuit is mounted on a sturdy 33-mm-thick sub-chassis weighing 15 kg, made from pure aluminium ingots, to achieve vibration control that minimizes the effect of vibrations from speakers.

TAD’S CUSTOM-MADE PARTS AND COMPONENTS

TAD’s custom-made electronic volume control circuit boasts ladder-resistance switching that TAD says achieves precise attenuation performance and an ultra-low distortion of less than 0.0005% at 1 Vrms input. In addition, the power circuit employs TAD’s custom-made electrolytic smoothing capacitors, as well as large-capacity, ultra-low-distortion film output coupling capacitors to achieve a wider low cut-off frequency range.

SYNCHRONOUS CONTROL OF MULTIPLE C700S

A master C700 can synchronously control several slave C700s connected to its MASTER OUT jack. This enables two or more C700s to provide a dual-mono configuration for monaural power amplifiers or to deliver three-or- more-channel sound reproduction.

TAD-C700 PREAMPLIFIER RECORDING OUTPUT AND PASS-THROUGH MODE

The C700 is equipped with a dedicated recording output that bypasses the selector circuit to directly output input audio signals. It also has a pass-through mode that outputs input signals from a pre-out jack without changing the signal level. A monitor switch is not available on the C700 to eliminate any chance of switching elements adversely affecting sound quality.
