CH Precision Digital Components Get Clock Sync Option Upgrade

CH Precision has released an upgraded clock synchronization board for their digital products – the D1.5 CD/SACD Player/Transport, the C1.2 DAC Controller and the I1 Integrated Amplifier (with its internal DAC). The units’ card-cage construction means that the new Clock Sync board is a simple addition to an existing product or replacement for the previous Sync I/O board.

Principal features include:

• New Clock Sync Board compatible with all current CH Precision digital components.
• Significant reduction in radiated noise, due to:
  1. Low Voltage Differential Signal (LVDS) internal output to the unit in which the Clock Sync board is mounted.
  2. New, four-layer circuit board that allows the use of complete ground planes on either side of the clock circuitry.
  3. The option to defeat unused 75Ω clock outputs.
• A choice of 75Ω or 50Ω connection (no High Z connection).
• Same price as previous Sync I/O board, with generous trade-in for existing boards.

The Clock Sync board allows optimized clock synchronization between CH Precision digital units, or the use of an external clock such as the T1 Time Reference. Despite offering the same sockets and looking almost identical to the previous version, the new board introduces a number of important new features and facilities and delivers a significant reduction in radiated noise, better preserves the low jitter levels of the incoming clock signal and improves compatibility with third party master clocks. The result is significantly improved performance, with easily demonstrable sonic advantages and musical benefits.

The new Clock Sync upgrade maintains CH Precision’s policy of protecting their customer’s investment by allowing products already in the field to be updated and kept fully current. The revised board ensures that the D1.5, C1.2 and I1 remain at the very peak of digital audio performance.

Product Compatibility

Please note that the new Clock Sync board is not operationally compatible with the earlier D1 and C1. However, Sync I/O and Clock Sync boards will communicate properly between units. So, for example, a D1 fitted with a Sync I/O board will still work perfectly, either directly linked to a C1.2 equipped with a Clock Sync board, or if connected to a T1 Time Reference Master Clock.

Price and Availability

At $1,500 USD (local prices apply) the price of the upgraded Clock Sync board remains the same as the Sync I/O board. Availability of the new Clock Sync boards is as of now.

Trade-in Scheme

Owners who return existing Sync I/O boards can take advantage of a 50% trade-in scheme, an offer that will run until May 31st 2024. The existing boards must be returned to CH Precision in order to qualify for the discount. This discount also applies to boards exchanged as part of a D1 to D1.5 or C1 to C1.2 upgrade
