Tiptop Audio Buchla 285t
285t Frequency Shifter 是一款功能強大且獨特的 類比訊號處理器，結合了 類比頻率移位（Frequency Shifting） 和 環形調變（Ring Modulation），能對任何訊號產生不諧波偏移（Inharmonic Shifts），並進行動態變換。該模組分為兩個部分：頻率移位與環形調變，可將音訊訊號依序通過兩個處理區塊，也可獨立使用兩部分。無論是從基本波形衍生新音色，還是將外部音訊轉換為超現實的音色，285t 都是一款強大的訊號處理工具，能為您的系統帶來全新的聲響可能性。
頻率移位 vs. 音高移位
與音高移位（Pitch Shifting）不同，音高移位會保持訊號內部諧波之間的間距，保留音色的特徵，而頻率移位則是對頻譜進行統一倍數的位移，產生不諧波變化，使音色與音高同步改變。只需將訊號接入 285t 頂部的 訊號輸入（Signal Input），即可在對應的插孔找到 總和輸出（Sum Outputs，上移頻率） 和 差值輸出（Difference Outputs，下移頻率）。頻率移位量可透過內部振盪器調整，範圍從 0Hz 至 1000Hz，亦可透過外部振盪器輸入進行控制。此外，內部振盪器支援 線性頻率調變（Linear FM） 以及 雙極性 CV 控制（Bipolar CV Control），提供更多聲音塑造的可能性。
環形調變（Ring Modulation）
在環形調變部分，285t 提供 載波（Carrier） 和 調變器（Modulator） 訊號輸入，左側輸出可獲得完整的 環形調變訊號（Fully Modulated Ring Outputs），而右側輸出則可進行變化幅度調變（Variable Amplitude Modulation），讓使用者自由調整從 0 到完全環形調變的強度。此外，還提供 CV 控制 及 極性調變器（Attenuverter），可細緻控制調變量。

Purchase FAQ
Q1. What is the inspection period?
According to the Consumer Protection Act, online purchases come with a 7-day inspection period starting from the delivery date. Please note that the "inspection period is not a trial period." The purpose is for you to inspect and review the product, not to use it. If you are unsatisfied after inspection, please do not open or use the product and follow the return procedures immediately.

Any missing, damaged, or incomplete items may affect your return rights and restoration costs may be deducted.
Q2. How do I process a return or exchange?
If you wish to return a product, please ensure it is in complete, new condition with the original packaging undamaged. This includes the product itself, accessories, warranty card, original packaging, and all accompanying documents. If the product is damaged due to reasons attributable to you, we may not be able to process the return, or repair costs may be deducted from the refund. However, products with manufacturing defects are exempt and qualify for unconditional return or exchange.
Please contact us by phone or email within the inspection period, providing the reason for the return/exchange, current product condition, phone number, and pickup address. We will arrange the return within 3-5 business days.
Q3. How will I receive my refund, and how long does it take?
Refund methods and timelines vary by payment method:
Credit Card: After we receive the returned product, the refund will be credited to your credit card account within approximately 5-7 business days. Depending on your billing cycle, the refund may appear on your current or next statement. Please confirm with your credit card issuing bank.
Bank Transfer: Please contact service [at] digilog.tw with your complete bank details (bank name, branch name, bank code, account holder name, account number). We will arrange courier pickup of the returned product and transfer the refund to your designated account within 5-7 business days.
Q4. Do I need to pay for shipping when sending products for repair?
Round-trip shipping costs for product repairs are the customer's responsibility.
