Details

Tube Box DS

The Pro-Ject Tube Box DS offers similar characteristics as the Tube Box S/E, but it also takes the sound performance and the feature-set to a whole other level when compared with its forebear.

Additional adaptation possibilities, including Pro-Ject's unique variable impedance dial and a switchable subsonic filter, make this new model ideal for use with high quality MM and MC cartridges. The high-quality valve output stage matches perfectly with these adjustment settings to produce a sound which far outweighs the product's attractive price point.

Key Features:

  • MM/MC switches on rear panel 
  • Unique continuously variable input impedance loading 
  • Switchable gain settings for MM and MC cartridges 
  • Capacitance switch for MM cartridges 
  • Switchable subsonic filter 
  • Dual-mono tube triode architeture 
  • Premium ECC-83 Golden Pin Tubes 
  • Ultra low-noise semiconductors 
  • SMD technology

Product Questions
What do I need to listen to my turntable?
A HiFi turntable requires a phono preamplifier (also referred to as a Phono Stage), an amplifier & speakers for you to listen to your music. The phono preamplifier may be separate, built into your turntable or more commonly built into your amplifier. You can also connect your turntable to a media speaker aux input using a phono preamplifier.
Can modern record players play 78rpm records?
Unless it explicitly states in the product specifications most turntables do not play 78rpm records. Some manufacturers offer modification kits but what is needed varies from model to model. Contact us with your turntable model number for personalised advice.
Why is my record playing at the wrong pitch?
Pitch is controlled by the speed of the turntable so it's likely that you have this set wrong. Some turntable have a button for speed control, others require manually changing by moving the belt position on the pulley. You may need to lift the platter on some models to access the pulley wheels.
Where can I buy replacement Styli & Belts?
We have a selection of styli, belts, spare parts & upgrades available in our turntable accessories & spares store here

If the part you require isn't listed please let us know via our Contact Us page & we will do our best to find the part you require.

Why is my turntable very quiet?
If your turntable is very quiet this is usually because you require a phono preamplifer for your system. If you have a phono pre-amplifer but the sound is still very quiet it maybe that you have a Moving Coil (MC) Cartridge on your turntable that specifically requires a Moving Coil Phono Pre-Amplifier. Some pre-amplifiers will have an MM/MC switch (Moving Magnet/Moving Coil) which can be changed for Moving Coil cartridges. Moving Coil cartridges are considered to give a far superiour sound but are also quite expensive so only tend to be fitted to high end turntables.
Why do turntables require a Phono PreAmplifier?
Turntables are a passive device with no internal amplification & give a very low output compared to other audio products. The Phono PreAmplifier boosts the output level to the same standard used by CD, Cassette, Radio etc.
How do I know if I need a Phono PreAmplifier?
If your HiFi amplifier has a phono preamplifier built in it will have a dedicated input on the rear labelled "Phono". Sometimes this is switchable via a toggle on the rear of your amplifier or via a software menu on the amplifier display & may need to be enabled to have effect. On some HiFi amplifiers the Phono input may have been an optional extra in which case there could be a label but no sockets. If there is no Phono PreAmplifier on your HiFi amplifier you will either need an external unit or a turntable with a built in PreAmplifier.

Modern media speakers designed for streaming can also be connected to a turntable if they have an Aux input. To do this you will need either an external Phono PreAmplifier or a turntable with a PreAmplifier built in.

How do I know if my turntable has a Phono PreAmplifier built in?
Most turntables do not have a PreAmplifier built in & it can sometimes be difficult to tell without checking the manual. If it does have a PreAmplifier there will sometimes be a switch on the rear of the turntable to toggle between Phono & Aux level output. You can also safely connect any turntable to an Aux input to check, if the volume is very low then a PreAmplifier will be required.
