- End User Guide
- Steered Current Source Technology (SCS)
Experience double the traditional output power with advanced, single-ended (SE) circuit design. This new level of performance is reached by using a fully linear, steered current source (US Patent 10256776) controlled exclusively by the tube’s output voltage. The excess of common large output transformers and associated hysteresis is eliminated, and as a result, lush detail in the midrange and masterfully articulated upper and lower frequencies are revealed. - Stepped Logarithmic Attenuator
A stepped logarithmic attenuator is used to mimic the response of human hearing. The attenuator consists of only discrete resistors in a ladder configuration that are switched in and out of circuit to produce a logarithmic attenuation of the output signal. - Interchangeable Transformer Block
The standard 8-ohm transformer block can be interchanged with the optional 4-ohm or 16-ohm version. This feature is unique to the 91E Integrated Amplifier and allows users to match speaker impedance for improved fidelity. Single impedance transformers maintain lower winding capacitance normally vitiated with multiple tap transformers. - LCD Display
A bright and easy to read color display shows the selected input, attenuator level, and VU meter. The display also shows settings which can be adjusted by the included remote control. The display is dimmable. - Remote Control
The included infrared remote control allows for quick adjustment of amplifier settings such as input levels, balance, and display dimming. - Six Audio Inputs
Up to six (6) source devices can be connected during amplifier operation. - Auto-Bias
Microprocessors automatically bias the 300B tube pair each time the amplifier is powered on. No manual adjustment is necessary. - BT Compatibility
BT compatible audio input is available for wireless convenience. - Software & Firmware Updates via Ethernet Connection and USB
