Japanese HiFi brand Technical Audio Devices Laboratories, Inc. TAD Labs, has announced the upgrade to the TAD-M1000 Evolution series with the launch of the TAD-M1000TX two-channel power amplifier. This latest upgrade adds various refinements to include; a redesigned circuit layout and power transformers.
The TAD-M1000TX employs a bridge-tied load (BTL) design that connects two separate amplifiers in a balanced configuration for the left and right channels in the amplification circuits from input through to the output stages. This design uses individual supplies for each channel ensuring that each channel receives symmetrical positive and negative power supplies. As the grounding configuration serves as the reference point for the signals symmetry, this was also updated together with the first amplification stage.
The Class D single-output-stages, each consisting of power MOSFET devices with ultra-low on-resistance support low power loss and therefore low heat generation, and provide high switching speeds supporting the amplifiers frequency response of 10 Hz to 50 kHz and power output of 500 watts per channel into 4 ohms.
The new power supply uses a pair of 1KVA toroidal transformers whose lead out wires are connected directly to the power supply circuit boards, removing any contact point resistance. Their new circular core design minimizing vibrations and flux leakage and therefore noise. Terminals for other boards and clamping screws are all made from oxygen-free copper and coated with nonmagnetic materials.
Rear panel connectivity includes, balanced XLR and unbalanced RCA inputs, two pairs of large gold plated speaker binding posts and a DC trigger input. With switching to control, input selection, bi-amping and auto-shutdown. Bi-amping is ideal for those speakers that can support individual inputs to their LF and HF drivers, helping to reduce cross-signal interference between them.
Finally, the 64lb (29Kg) body of the TAD-M10000TX uses a three-point support structure with internally inverted spikes, which helps to isolate its chassis and electrical components from external vibrations.
