Rega AURA Manual De Instrucciones página 4

Connections
The input can be made via RCA (phono) connectors and the output via either RCA (phono) connectors or balanced XLR connectors
(pin2 positive and pin3 negative). The input and output sockets are marked by colour to indicate left and right channels, White for
LEFT and Red for RIGHT. If your turntable has a separate Earth wire, firmly connect it to the terminal provided on the rear panel. N.B.
Always switch both pre and power amplifiers off before changing the leads.
Mains Lead (Supplied)
A Rega designed, fully shielded, high current capacity mains power lead is included.
High Quality Interconnect (Supplied)
A Rega designed high quality RCA (phono), unbalanced interconnect is included. It was used throughout the design and development
of the product and can be considered as a component rather than an accessory. The Rega cable is double shielded and exhibits an
extremely low capacitance offering uniquely high levels of quality and performance.
Cartridge Selection
The Aura phono pre-amplifier is not suitable for use with any moving magnet (MM) cartridges; it can only be used with moving coil
(MC) cartridges. The Aura has been designed to work with most manufacturers' moving coil cartridges.
There are five different input load and capacitance settings. Select the required load and capacitance to match to that specified
by the cartridge manufacturer. Note: It is permissible to try different loading capacitance conditions as sometimes changing the
resistive and capacitive loading gives a different sonic performance more suited to your personal taste. Your Rega dealer will be able
to give guidance to help match your specific cartridge to the correct gain settings. It is worth noting some 'legacy' pre-amplifiers
exhibit higher resistive and capacitive loading.
Powering Up
The Aura is activated by depressing the ON/OFF switch situated to the left of the front panel. Power on is indicated by the REGA
LOGO in the centre illuminating red. It is recommended to activate the Aura before the power amplifiers and deactivate after
they have been switched off. After switching off, the indicator will extinguish. This Rega pre-amplifier circuit has been carefully
designed to work with a minimal "warm up" period. Some manufacturers and retailers may recommend leaving amplifiers
permanently switched on. Rega cannot condone such practice in these environmentally sensitive times. We would recommend that
your Rega amplifier is always switched off after use. Full sound quality is attained after less than ten minutes (a process speeded up
by playing music).
Gain
Please note: mute or turn the volume control to minimum when changing the gain setting. The gain setting switch selects the
voltage gain of the phono amplifier. Gain I selects 69.5 dB (switch out) and Gain II selects 63.5 dB (switch in); this will provide an
input sensitivity of 67 µV and 131 µV respectively for an output level of 200 mV unbalanced and 400 mV balanced. The balanced
output is effectively 6 dB higher than the unbalanced output. It is advisable to start with the lower gain setting II and if necessary;
increase the gain level to I if more level is required for lower output cartridges. Because the balanced output is effectively 6 dB
higher, it could be advisable to select gain II setting when using the balanced output; this will also depend greatly on the sensitivity
of the connected amplifier.
Capacitance
There are five different input capacitance settings of 1000 pF, 2000 pF, 3200 pF, 4300 pF & 5700 pF. Select the required capacitance
to match to that specified by the manufacturer in the cartridge specifications. It is permissible to try different loading conditions
as sometimes changing the capacitance gives a different sonic performance more suited to your personal taste; this also applies if
there is no loading capacitance specified by the manufacturer. To match some 'legacy' pre-amplifiers, select 5700 pF. The 1000 pF
setting is optimised for the Rega range of MC cartridges.
