KingRex Pre-Amp
It has been a long time coming, but finally a Pre-Amplifier designed for "T-Amps" is available. KingRex have answered our prayers and released the Pre-Amp! Designed ground up specifically for "T-Amps" this pre-amplifier is brilliantly executed, with a highly effective and technically sophisticated design. The KingRex Pre-Amp delivers versatility, value and performance.
Two Input Sources
High-quality gold-plated RCA jacks provide two source inputs. The source is selected automatically depending on which is generating the signal. Switching is carried out via a CMOS digital integrated circuit, the Toshiba TC4001B. When using two sources, the one not being used is muted or turned off.
Quality Parts
Key components include three pairs of Burr-Brown ICs: OPA627 for pre-amplification, BUF634 for increasing and sustaining higher output current, OPA177 for DC servo.
- The Pre-Amp uses a low-noise FET input Op-Amp. The highly-regarded and expensive OPA627 is used as the main Op-Amp. A new-generation FET (Difet) Op-Amp, it is known for its low noise and high speed.
- The BUF634 is a high-speed Op-Amp used to increase and sustain higher current output. It also improves the compatibility with power amps and loudspeakers.
- OPA177 makes sure the Op-Amp output is free of DC, avoiding any chances of harming your amplifier and loudspeakers.
- The KingRex Pre-Amp, like all KingRex audio components, is cased in black steel with a heavy anodized aluminium faceplate and recessed volume knob.
Designed for Sonic Excellence
- The addition of the OPA177 as a DC servo circuit eliminates output coupling capacitors, resulting in a purer and more accurate representation of the original source.
- A built-in 'diamond buffer' stage is added at the input to increase the dynamic range.
- When matched with low-power amps, it will improve compatibility and performance with lower-efficiency speakers.
Easy to Upgrade
- To help you find your favourite sound, KingRex designed the Pre-Amp with socketed Op-Amps. This allows you to change the Op-Amp when new and better units become available.
