Проигрыватели виниловых дисков — Audio-Technica AT-LP70XBT

Audio-Technica designed the AT-LP70XBT as a record player with automatic arm operation, belt drive, a built-in Bluetooth transmitter and a fixed AT-VM95C dual moving-magnet stereo cartridge. It combines a wired output, a switchable phono preamplifier and wireless streaming in a compact chassis that comes with a dust cover.

Key specs that matter

Its DC motor spins the die-cast aluminium platter via a belt, with 33-1/3 and 45 RPM available. Wow and flutter is below 0.25% weighted, and signal-to-noise is above 55 dB. Phono output is 4.0 mV nominal and line output is 252 mV nominal, both measured at 1 kHz and 5 cm/sec, and the preamp gain is 36 dB nominal with RIAA equalisation. The deck measures 400 x 330 x 110 mm across width, depth and height, and its mass is approximately 2.9 kg.

Engineering and use context

The arm offers 220 mm of effective length, an overhang of 18 mm and a maximum tracking error angle below 2.0 degrees. The AT-VM95C cartridge cannot be removed from the arm, and its aluminium pipe cantilever holds a 0.6 mil bonded conical tip with a recommended load impedance of 47,000 ohms. When the stylus wears out, the AT-VMN95C replacement fits, and a dedicated AT-LP70X belt is sold as a spare. The wireless section runs Bluetooth version 5.2 with the A2DP profile and supports the aptX Adaptive, aptX and SBC codecs, transmitting at 2.5 mW EIRP over roughly 10 m line of sight. Power comes from a 12 V DC adapter on a 1.5 m lead, and consumption is 1.6 W. The accessories list covers a felt mat, a 45 RPM adapter and a 1.0 m RCA cable.

The arm starts, lifts and returns on its own at the start and end of a side. The supplied AC adapter accepts 100 to 240 V AC at 50 or 60 Hz with a rated input current of 0.4 A, and delivers 0.5 A at its output. Bluetooth transmission uses the 2.402 to 2.480 GHz band with GFSK, Pi/4DQPSK and 8DPSK modulation.

Pairing

Set to line level, the output feeds an amplifier line input or active speakers directly, while the phono setting lets the signal go to a separate phono stage. Wireless playback works with Bluetooth headphones and speakers, with aptX Adaptive available when the receiving device also supports that codec.

Alternatives

The Audio-Technica AT-LP3XBT is a heavier 5.0 kg automatic Bluetooth turntable that uses a removable AT-HS3 headshell for its cartridge.
