- Page 8 Important Safety Note Before connecting your amplifier to mains power, ensure that the power control key switch on the preamplifier is in the ‘Off’ position, and the (three) rocker switches at the rear of the preamplifier and both power amplifiers are also in the ‘Off’ position. Connecting the power amps to mains power Connect the three IEC power cords to the outlets on all amplifiers, but do not plug them in to mains power until you have connected your...

Page 9: Connecting Your Amplifier To Other Components
Note: We recommend using heavy gauge speaker cable for the best quality sound (the heavier, the better, and with a 2mm minimum). (e.g. REDGUM RGAEL - 7AWG/10mm² high Damping Factor speaker cable) -

Left channel and the red plug for the Right channel. We recommend the use of high quality RCA interconnects wherever possible, for the best quality sound. (e.g. REDGUM's RGAP 05, RGAP 1 & RGSil) The amplifier inputs are all the same sensitivity, and will accept a signal from any line-level source (Media servers, Tuner, MP3, Mini Disc, DAT player, VCR, etc.). -
Page 11: External Power Amplifier
External power amplifier Your REDGUM amplifier comes with ‘Preamp Out’ sockets. This allows the amplifier’s preamp stage to be connected to an external power amplifier if desired. To do this, connect your REDGUM amplifier’s outputs marked Left/Right preamp Out to the corresponding Left/Right preamp Inputs on the external power amplifier using high quality RCA interconnects. -
Page 12: How To Use Your Redgum Amplifier
How to use your REDGUM amplifier At the front of your amplifier is an on/off switch, and three controls. Fully manual units have three rotary controls whereas remote controlled units have a fixed input control. These controls are used to turn the amplifier on and off, select the input source, and adjust the volume, thereby achieving the Dual Mono balance. -
Page 13: Why Do I Hear Sounds When Turning On And Off
In greater detail, REDGUM amplifiers make audible 'thunks' when powered up and down, but usually only the latter ones are noticeable to people. A REDGUM amplifier has no need to mask this sound with a troublesome relay in the speaker line. In fact, customers can be reassured that this sound is a healthy sign that the amplifier is flexible enough to cope with such rapid changes in the power supply. -
Page 14: Volume And Balance Control
To protect your equipment, always check that the volume is turned down before changing the input source. Volume and Balance control REDGUM amplifiers are available in two versions using Dual Mono volume controls – manual or remote control. For both manual and remote versions, the Left rotary control affects the volume of the Left speaker and the middle rotary control affects the volume of the Right speaker. -

The angle (“toe-in”) of the speakers At REDGUM Audio we recommend a 30 degree angle between the speakers. This provides a strong central image in Stereo, as well as suitable 'timing' to provide good rear projection for Home Theatre. You... -
Page 16: Your Listening Room
Your listening room Strange as this may sound, the room itself will have a profound affect on how your audio system responds. In fact, many experts consider the room to be as important to the sound as any other component in your system! Did you ever notice how it’s difficult to talk in some restaurants because you can’t hear each other over all the other conversations... -
Page 17: Other Helpful Hints
Other helpful hints Corrosion and sound system terminals Atmospheric corrosion can build up on speaker cable and interconnect terminals over time. Should this occur, removing and re-inserting wires and cables will improve the contact and hence the quality of signal transmission. -
Page 18: Troubleshooting
There is no technical basis to insist on either action. But from a power consumption point of view, it is worth noting that since 2008, all REDGUM amplifiers have used a stand-by power system incorporating a highly efficient miniature power supply that powers a microprocessor using 'nanowatt' technology. - Page 19 Lost key Lost keys can be replaced, as information is kept on file at the REDGUM factory about every product we manufacture. If you provide us with the Serial Number of your product (look under the amplifier, on the carton, or on the final test report issued with the product), we can provide you with another key.
