Sony PS-LX310BT Review

What Sony has actually built here

The PS-LX310BT is a belt-drive, fully automatic turntable with an aluminum die-cast platter and a straight aluminum tonearm. So far, so ordinary. What makes it unusual is the back panel, which offers three separate ways out of the deck: RCA, USB and Bluetooth, with a switchable phono stage feeding the first two.

That is a genuinely different proposition from the decks it competes with. Most turntables at this money give you one output and expect you to build a system around it. This one is designed to slot into whatever you already own — a Bluetooth speaker in the kitchen, a laptop, a soundbar, an old receiver — without you buying anything else.

The three gain settings, which nobody explains

The specification that gets skipped over is the three-position gain switch, and it is the most quietly useful thing on the deck. Gain is how much the internal preamp amplifies the cartridge’s output before it leaves the turntable.

Why three positions matter: the correct output level for a Bluetooth speaker is not the same as for a receiver’s line input, and neither is the same as what a computer’s recording input wants. Too much gain and the signal clips — on a digital recording that is permanent, audible distortion on the loudest passages. Too little and you raise the noise floor along with the music. Most decks give you one fixed level and leave you to cope. Being able to pick is a real advantage if you use more than one of the three outputs, and the reason it exists on a deck that also does USB.

Set it by ear with the loudest record you own: turn it up until the peaks distort, then back off one position. Our gain and impedance guide explains the underlying arithmetic if you want the reasoning rather than the recipe.

The tonearm is the limit

Here is the honest ceiling. The arm is a straight aluminum pipe with no counterweight, because that is what full automation at this price requires: the cueing mechanism is mechanical, driven off the platter, and it needs the arm to be a known, fixed mass with a known, fixed tracking force.

The consequences are the same on every automatic deck in this class, and worth stating plainly:

• Tracking force is set at the factory and is correct for the fitted cartridge. You cannot change it, and you have no reason to unless you change the cartridge.
• You cannot change the cartridge. A different pickup has a different mass and wants a different force; there is no counterweight to rebalance the arm with. The stylus is replaceable; the cartridge is not, in practice.
• There is no anti-skate dial, because there is no variable for it to compensate.

None of that makes the deck bad. It makes it a finished product rather than a platform. If you want to start with an elliptical cartridge and later fit a micro-linear, you want a manual deck with a counterweight — the Fluance RT81 is the standard answer at a similar price, and the trade is set out in automatic vs manual.

Bluetooth: what it is good for

Bluetooth on a turntable is a convenience feature that gets argued about as if it were a fidelity feature. Two facts settle it.

First, Bluetooth is lossy. The signal is compressed to fit the radio link and decompressed at the other end. On a wireless speaker in a kitchen that is inaudible in any meaningful sense; on a good pair of speakers in a quiet room, next to the same record played over the RCA outputs, it is not.

Second, there is latency— a delay of tens to hundreds of milliseconds. Irrelevant for listening, fatal if you ever want to play along with a record on an instrument.

The right way to think about it: the wired output is the deck’s real output, and the Bluetooth is a second, lower-quality one that costs nothing to include and occasionally saves the day. Sony giving you both, rather than making you choose, is the correct design. Our Bluetooth turntable roundup goes through the codec question in more depth.

USB, and what it does not include

The USB output turns the deck into an audio input device for a computer. Plug it in, select it as the recording source, and any audio application can capture the side.

What Sony does not bundle is software worth using. That is fine — the free options are better than what typically ships in the box, and the workflow (sample rate, level, splitting tracks, tagging) is the same regardless of the deck. We cover the whole process in how to record vinyl to a computer.

One caveat specific to this deck: because the internal preamp is switchable and the gain is adjustable, it is possible to record at a level that is far too hot or far too quiet without realizing. Set the level with the meters in your recording software before you commit a side to disk.

Setting it up

Almost nothing to do, which is the point of an automatic deck. Fit the platter, drop the belt over the pulley, place the mat, remove the stylus guard, choose the speed, press start. There is no arm to balance, no tracking force to dial and no anti-skate to match.

The two decisions that areyours: set the PHONO/LINE switch correctly for what you are plugging into — LINE for powered speakers, an AUX input or the Bluetooth path, PHONO only if the receiver has its own phono stage — and pick a gain setting. Getting the first one wrong is the most common “my new turntable sounds broken” complaint there is, and phono vs line explains why.

Who should buy it

Buy the PS-LX310BT if you want records to play through equipment you already own with the minimum of new purchases and no setup ritual; if a Bluetooth speaker is part of your listening life; or if digitizing a collection is on your list.

Buy the AT-LP60X instead if you want the same automatic simplicity for less and do not need wireless or USB. Buy the Fluance RT81 instead if you want an adjustable arm and a cartridge upgrade path, and are willing to cue by hand for it. And if USB recording is the actual priority rather than a bonus, the AT-LP120XUSB does that job with a proper adjustable tonearm attached — see the USB roundup for the full field.
