3510 Series

Its whole job is getting out of the way.

A full-width preamplifier with discrete Class A output buffers and a custom-wound toroidal transformer, drawing under 25 watts to do one job properly. Designed and built in Lancing, West Sussex.

Separates

Exposure has been splitting pre from power since the Roman numerals.

The III preamplifier and IV power amplifier arrived in 1977, and separate power supplies followed in 1981. The 3510 tier is the current version of that idea: a preamplifier, a stereo power amplifier, a pair of monoblocks and a CD player, all in matching casework. This is the box the rest of it plugs into.
  1. XMHalf-width separates. Phono, integrated, pre, mono, headphone, CD.
  2. 2510Full-width. Seventy-five watts, with an MM phono stage as standard.
  3. 3510The complete tier. Integrated, pre, stereo power, monoblocks and CD.You are here
  4. 5510The current flagship. One hundred and twenty watts, black only.

Distortion, Noise, Draw

What a line stage is for.

0.005% distortion

Measured at 1 kHz, referenced to rated output. Six times lower than the same tier's integrated amplifier, which is what taking the power stage out of the box buys you.

100dB signal-to-noise

A-weighted, and the floor a preamplifier has to hold if the amplifier behind it is to have anything clean to work with.

25W consumption

A line-level box has no business drawing more. Discrete Class A output buffers, and a custom-wound toroidal transformer with hum shielding.

Why buy a separate preamplifier instead of the 3510 Integrated?
Distortion. The integrated is quoted at under 0.03% and this preamplifier at under 0.005% β€” six times lower β€” because the line stage no longer shares a chassis and a power supply with the output devices. Pair it with the 3510 Stereo Power Amplifier or a pair of 3510 Monos.
Can it take a phono or DAC board?
The plug-in bay is documented for the 3510 and 5510 integrated amplifiers and the 5510 preamplifier. If you need phono on a separates system, the XM3 Phono Amplifier is the standalone answer β€” ask us and we will confirm current board fitment for your chassis before you order.
What power amplifier should follow it?
Within the tier, the 3510 Stereo Power Amplifier at 110 W per channel, or a pair of 3510 Mono Amplifiers if you want a chassis and a power supply per channel. Both are the same width and finish, so the stack matches.
Where is it built?
Exposure designs and builds it in Lancing, West Sussex, where the company has operated since 1974. Three-year guarantee.
About the Exposure 3510 Preamplifier

Reference Thinking, Real-World Price: Exposure 3510 Preamplifier

The Exposure 3510 Preamplifier is a high-end British preamp inspired by the award-winning 5010 reference design β€” and built to punch well above its price. A new gain stage with high-quality relays and an oversized toroidal power supply deliver clarity and quiet that belong to far dearer components. Hi-Fi News gave the 3510 pre/power its "Outstanding" badge, noting a design in which "simplicity has been elevated almost to an art form."

Discrete, Quiet, and Beautifully Simple

Inside, discrete transistors in the line stage and an optimised PCB layout keep crosstalk low, while a carefully designed hybrid power supply achieves very low residual noise. The result is a preamplifier that gets out of the music's way. Controls are refreshingly minimal β€” no cluttered menus, just clean, intuitive operation and a newly designed remote that switches inputs, mutes, and controls volume from your chair.

Configure It Your Way

Plenty of inputs are provided, with slot-in options for onboard MM phono, MC phono, or a high-resolution DAC β€” so you build exactly the preamp your system needs and nothing you don't. The aluminium front plate and chassis aid cooling and keep noise at bay, in black or titanium.

Why You'll Love the Exposure 3510 Preamplifier

  • 5010-reference inspired β€” flagship design thinking at a fraction of the price
  • New relay-switched gain stage β€” clean, precise, channel-matched control
  • Oversized toroidal PSU β€” quiet, stable power for a black background
  • Modular options β€” add MM phono, MC phono, or a hi-res DAC board
  • Discrete line stage β€” optimised layout for low crosstalk and noise
  • "Outstanding" β€” Hi-Fi News β€” remote included, black or titanium

Frequently Asked Questions

Can I add a phono stage or DAC to the 3510 preamplifier?

Yes. The 3510 preamp accepts slot-in option boards for moving-magnet phono, moving-coil phono, or a high-resolution DAC, so you can tailor it to your sources.

What power amplifier should I pair it with?

The Exposure 3510 stereo power amplifier or 3510 mono power amplifiers are the natural partners, forming the "Outstanding"-rated 3510 pre/power system.

Does it come with a remote control?

Yes β€” a newly designed remote lets you switch inputs, mute, and adjust volume from your listening position.
