The upgrade KIT
Success
Kits are funded through a crowdfunding scheme with minimal markup.
- DSP board — $230 (recalculation from alternative manufacturers expected) Boards are supplied fully activated and connected to the update and remote servicing server.
- Front panel board (with smart LEDs) — $150
- Display board (AMOLED TFT module) — $70
- PDB board — $30
- Adapter cable for PDB connection (Ethernet + USB 2.0) — $4
- New anodized front panel — $40
- Mounting hardware, knobs, button caps, heatsink, headphone jacks — $20
Information
The upgrade kit is designed for user self-installation.
Basic technical knowledge and electronics skills are required:
- Install and solder the headphone and microphone jacks
- Reconnect internal connectors
- Perform assembly: secure the boards and install everything into the enclosure
- Set the amplifier transistor quiescent current
- Recalibrate output power according to the user manual
The work does not require professional manufacturing, but calls for care and a basic understanding of electronics principles (soldering, connecting, tuning).
If difficulties arise, assistance is available from:
Andrey UX4LR
Pavel UR6EA
Support is provided via the Telegram channel, where colleagues will help with installation and configuration questions.
Warning
Yes, of course — you can count on help if the self-install does not succeed.
I, as well as Pavel UR6EA and Andrey UX4LR, are ready to assist with installation and configuration.
In addition, a remote monitoring and configuration system via console is available. Upon user request, we can connect and promptly resolve software issues.
Support is also available through the Telegram channel for quick resolution of any questions.
Error
Yes, there are several points to keep in mind:
- The current unstable political and financial situation is affecting the components market and logistics.
- This has been especially pronounced in the memory market — due to sharp price spikes, the cost of memory components (DDR3 eMMC) has increased up to 5 times.
- As a result, the configuration had to be optimized: the eMMC capacity was reduced from 32 GB to 16 GB.
- Prices are currently fixed based on quotes already received from Chinese manufacturers, but they may change in the future.
- The first batch of DSP boards (the most expensive and critical component) is being assembled on a pre-order basis:
- Once registration closes, the total number of participants is finalized.
- An order is placed with the manufacturer for the remaining boards.
Important: Additional individual upgrades after the batch is formed are not currently planned, so it makes sense to decide in advance in order to be included in the current delivery.
