01 · Delivery times

When will my order arrive?

Sourcing records and CDs is complex. So that you always know where you stand, we show the delivery time on every item as precisely as possible. Our focus is on audiophile records and CDs – in close cooperation with Sieveking Sound, whose stock is shown in the shop on a daily basis.

For items not in stock, a direct stock check isn’t possible while you order. We check availability immediately afterwards and inform you without delay.

How to read the delivery time: The colour of the delivery van icon on the item matches the colour of the dot in the table.

Several items, not all in stock? Here’s how we ship

For orders of records and CDs where not all items are in stock, we proceed as follows:

1	Shipped together As a rule, we first reorder missing items so we can send your order in one parcel wherever possible.

2	Immediate partial shipment if the wait is longer If we see right away that an item will take longer, we send you the available items straight away as a partial shipment.

3	Automatic check every 14 days Every 14 days, our system automatically checks whether a further partial shipment can be sent on its way.

Accu Box S2 - Battery power supply - silver - Pro-Ject

The external battery power supply for all Pro-Ject S2 devices.

External battery power supply
For two Pro-Ject S2 devices
Clean power, clean sound
Mains-independent battery operation
5V and 18V power supply
Microprocessor automatic charging

Even the best hi-fi components don't stand a chance against a poor power supply. And the enemies of a clean mains current lurk everywhere: computers, lamp dimmers and other electrical villains scatter interference components into the home mains. As a result, the transparency of the reproduction suffers, details and dynamics are lost. It seems as if a (gray) veil covers the music.

The Pro-Ject Accu Box S2 provides a remedy for two devices of the S2 line with 5V/DC and 18V/DC power supply. It can be used in battery-only mode or while charging. As a rechargeable battery, it supplies its energy completely independent of the mains supply and thus maximally clean. During the charging process, the separation from the mains is removed - however, the rechargeable batteries then act as a buffer and thus as an effective mains filter. After the batteries have been fully charged, the power supply unit and the charging system are disconnected from the batteries by the microprocessor-controlled automatic charging system. Interference components coming from the mains can no longer affect the sound, and fluctuations in the mains voltage have no effect on the power supply to the connected device. In addition, ground loops are prevented.

Very practical: When the Pro-Ject Accu Box S2 is switched off, devices connected to it are automatically switched off. If the Accu Box S2 is switched on, devices without a stand-by switch, such as the Pro-Ject Pre Box S2 Digital, are also switched on.
Housing made of brushed aluminum in silver or black.

Technology

Recommended for S2 line devices with 5V/DC and 18V/DC power supply.
Two power supply connectors:
1x 5V/DC to supply devices such as Pre Box S2 Digital, DAC Box S2+, Head Box S2 or Head Box S2 Digital.
1x 18V/DC to supply devices like Phono Box ultra 500 and Stream Box S2 Ultra
Microprocessor controlled automatic charging with display of charging function
Batteries in lithium polymer technology
Playback time: depending on the connected device
Charging time: approx. 3 hours. The charging time is extended if the connected device is in operation during charging
