CD/SACD-проигрыватели и транспорты — Rotel RCD-1572MKII

The RCD-1572MKII is a Rotel compact disc player built in a 2U height chassis, with a fully balanced, true differential XLR output alongside RCA analogue and coaxial digital outputs. Rotel places it in a line of CD players the company has produced since 1989, and two finishes are listed, silver and black. Rotel quotes the front panel height as 88.1 mm, the 2U rack standard.

Key specs that matter

Conversion uses a Texas Instruments 32-bit converter rated at 384 kHz. THD with noise sits at 0.0035% at 1 kHz, matched by the IMD figure, and frequency response covers 20 Hz to 20 kHz within 0.5 dB. Signal to noise ratio exceeds 118 dB A-weighted, channel separation also exceeds 118 dB at 10 kHz, and dynamic range is above 99 dB. Channel balance is within 0.5 dB and phase linearity within 0.5 degree. At 0 dBFS the RCA output delivers 2.2 V from 100 ohm and the XLR output 4.5 V from 200 ohm. The coaxial output gives 0.5 V peak to peak into 75 ohm. Power consumption is 15 W, dropping below 0.5 W on standby. Dimensions are 431 x 104 x 320 mm, and net weight is 7.34 kg.

Engineering and use context

Rotel powers it from an ultra-low noise toroidal transformer manufactured in-house by Rotel. The analogue and digital audio circuits, the function control circuits and the disc motor supplies are each fed from their own transformer windings, every one with dedicated voltage and current regulators for noise isolation, and custom circuit board layout separates these sections further. After the converter, Rotel applies its proprietary Balanced Design Concept along with analogue output filters outside the DAC chip that Rotel tuned for a precise frequency response. The disc tray slides out with a smooth action, and the unit is operated from front panel buttons with a display or from the infrared remote.

Pairing

The XLR output suits amplifiers and preamplifiers with balanced inputs, while the RCA pair serves unbalanced inputs and the coaxial socket can feed an external DAC. An RS232 port, a trigger socket for 12 V and a wired IR input support integration with control systems, and optional rack ears allow the player to be mounted in an equipment rack. It is supplied in 120 V at 60 Hz form for the USA and 230 V at 50 Hz for Europe.

Alternatives

The Rotel CD14MKII is a smaller CD player with RCA analogue and coaxial digital outputs, a 32-bit Texas Instruments converter and a net weight of 6.51 kg.
