What is Balanced AAVA volume control on the E-5000, and what makes it different?
Balanced AAVA operates without variable resistors in the signal path and instead uses multiple signal chains whose configuration changes based on the position of the volume knob, which drastically reduces noise and distortion.
How does loudness compensation affect sound quality at low volumes?
The loudness function compensates for the loss of clarity at low volumes by boosting the frequency around 100 Hz, ensuring that the sound remains full and balanced even at low volumes.
Does the E-5000 support bi-amping, and how do you set it up?
The E-5000 features both pre-out and power-in connections in unbalanced (RCA) and balanced (XLR) versions, enabling bi-amping by driving the low- and high-frequency ranges with separate amplifiers.
Which optional modules can be added, and what do they offer?
There are two expansion slots available for cards such as the AD-50 (phono for MM/MC), the DAC-60 (digital-to-analog converter), and the LINE-10 (high-level input), which expand the unit’s functionality.
How does the short-circuit protection work, and what is a MOS-FET switch for speaker output?
Instead of relays, the E-5000 uses MOS-FET circuits with very low internal resistance (1.9 mΩ) for speaker protection, which increases reliability and minimizes the impact on sound quality.
What control buttons or functions are located on the front panel?
Behind a flap are buttons for selecting the input, tone control (bass/treble), balance control, phase selection per input, mono/stereo switching, speaker A/B, and speaker selection.
How do the input selections work, and how many are available?
There are five unbalanced line inputs (RCA), two balanced inputs (XLR), plus main inputs and pre-outputs in both RCA and XLR formats, allowing you to connect multiple sources and use the unit as a power amplifier.
Is the E-5000 compatible with low-sensitivity speakers, and what are the impedance requirements?
Yes, thanks to its output power of 240 W at 8 ohms (320 W at 4 ohms) and a high damping factor of 1,000, it can handle low sensitivity and complex impedances. Suitable for speakers with an impedance between 4 and 16 ohms.
Can the E-5000 be used as a standalone power amplifier with an external preamplifier?
Yes, the MAIN IN inputs allow you to use only the power amplifier section in combination with an external preamplifier; the CV Tai input supports both balanced and unbalanced signals.
How is the power supply and power consumption managed, and what should be taken into account during installation?
Power is supplied by a toroidal transformer with two large 40,000 µF filter capacitors, and the standby power consumption is approximately 98 W; power consumption under load can reach up to 570 W according to IEC-60065, so a robust power supply is required.
