ePot.V4 bundle
The V4 bundle combines a V4 electronic stepped-attenuator and preamp controller board together with its companion OLED display module, rotary manual encoder, and infrared remote. These form the core of a passive LDR preamp.
The bundle offers a 15% discount over purchasing these individually.
We offer optinoal items for the V4 system (solid state buffer & power supply) that are NOT included in the bundle.
Please be aware that the V4 bundle and the various V4 options do NOT constitute a complete turnkey preamp kit.

The V4 can be purchased by itself, both with and without an LDR module and/or a remote. Click here to check out the ePot.V4 by itself. |
The V4 “bundle”
The V4 bundle combines the ePot.V4 board together with its LDR module, OLED display assembly, and infrared remote into a single convenient package discounted at 15%. The bundle is a collection of parts we make and/or sell but does not represent a comprehensive preamp project kit (see “what’s not included” section below). You can also purchase all these parts separately.
The bundle provides the passive version of the V4 by itself. The active version is identical except for the addition of a SSBM.V4 solid state buffer module that mounts directly to the V4 board itself. The SSB.V4 buffer board turns the passive V4 into direct coupled active preamp with optional gain. To be clear, the bundle does not offer an active option but a buffer can be purchased separately.
What’s included?
The following items are included with each V4 bundle:
-
A fully functional V4 board that has been calibrated
-
Quad LDR module installed in the V4 board, tested, and calibrated
-
OLED display assembly already tested including encoder, IR receiver, and cabling
-
Infrared remote control
-
Power cabling to the V4 board
-
4 sets of mounting standoffs with screws
What’s optional
The following options are available for the V4:
-
SSBM.V4 solid state buffer module – plugs directly into the V4 board, transforming the passive V4 into an active preamp/attenuator.
-
LPS5.V4 5 volt linear power supply – a low noise 5 volt linear power supply in lieu of providing your own 5 volt power source.
What’s NOT included that you’ll need?
The following items are not provided but are typically required to have a fully functioning V4 system:
-
RCA and/or XLR audio jacks and sockets for connecting audio signals to the V4 board
-
A 5 volt power supply rated at least 1 amp. You can probably get away with a 0.5 amp power supply but we recommend 1 amp.
-
Some type of enclosure or plinth to which you can mount all the V4 hardware. If you’ve never built your own preamp or amp before, please be aware that the greatest build challenge is often the enclosure needed to accommodate everything effectively.

V4 manual
The V4 Preamp Controller Manual covers the full V4 system in one place: how to operate it via infrared remote, local rotary encoder, and its menu-driven OLED display, plus the design basis, hardware features, and interfaces of the ePot.V4 board itself.
