2008多項課程召集 - (6) UCD 後級製作班 (仍可享舊價優惠) 已完結

I really want to join this class, but I cannot confirm my time available now due to some jobs oversea. But, may I reserve a seat first and confirm early Feb. May target UcD Class D module is UcD400 HGHXR.

You can listen to the UCD400AD on the coming Sat when you completed your preamp.[/quote]


Is this demo in coming Sat (1-Mar-08) opened to public or just for the students of pre-amp class?
How is about Vincent's (ref: 11:27 am dated 14-2-08) suggested demo in 8-Mar-08?

It is a mathematical course. Please note the following equation:

Total cost (HK$): X1 + X2 + X3 + X4 + X5 + X6 = HK$ 5700

Remark:
X1 = UcD180HG-HXR 模組 x2pcs
X2 = UcD Supply HG Mono 電源組件 x2pcs
X3 = Transformer 變壓器 x2pcs
X4 = 機箱 x1 pc
X5 = All accessories: RCA connector, Output Connector, cable, Switch, etc..
X6 = Training overhead cost

Data:
X1 = HK$ 2100x2 = HK$ 4200 (Ref: HiFifever website)
X2 = HK$ 1200x2 = HK$ 2400 (100 Euro /each, Ref: Hypex website 1 Euro = HK$12)

Subsitute the data into the equation, we have:

4200 + 2400 + X3 + X4 + X5 + X6 = 5700
=> 6600 + X3 + X4 + X5 + X6 = 5700

The equation is valid if only if X3, X4, X5, X6 are negative number. It is self-explained that the UcD180HG-HXR module will be purchased from Hypex, other components will be sourced from other.
I have listened the demo. The sound quality of this machine is good. Since I have personal business to resolve recently, otherwise, I have already made the deposit. Hence, my comment is that the price is reasonable.

[quote:f8b1af0158="Admin"]alant, thanks for the explaination.

We have the option to use UCD HG supply / HG supply mono, just to pay the product value and you can build that with your UCD.[/quote]

It is a judgement between cost and patent technology. The Class D technology of UcD 180/400 HG-HXR is a patent module. Hence, requires to buy from Hypex although expensive. For other components such PSU, transformer, softstart unit, etc..., local customer-made components are good alternative if there is no significant difference in sound quality between local and Hypex material. In fact, both cases will be considered if I confirm to start. Thank you for information.
