Now that you’ve heard the story of the Australian river red gum, it’s time to listen to your very own REDGUM. We’ve carefully selected and lovingly crafted each piece before coupling it to some of the finest audio engineering that money can buy.
Carefully unpack each one and inspect each component. In the first carton there should be: an Owner’s Manual the On/Off key a REDGUM key ring 2 remote control handsets, 1 as spare six RCA cables (3 x twin cables) ...
Setting-up your amplifier Your amplifier consists of two components, a pre-amplifier and a power amplifier. You need to connect these components together before you can use your amplifier. Important Safety Note Do not plug-in any equipment to mains power until all connections have been made between your pre- and power amplifier, and your amplifier and other equipment.

Connecting the ‘power control’ cables Connect the 3.5mm phone plug ‘power control’ cable from the remote switching ‘out’ socket on the pre-amplifier to the remote switching ‘in’ socket on the power amplifier, as shown on the diagram below. Connecting the amplifier to mains power Connect the two IEC power cords to the outlets on your pre- and power amplifier, but do not plug them in to mains power until you have connected your speakers and source components to your amplifier.
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) Subwoofer If you are using a subwoofer, there are two methods available to connect it to your amplifier.

We recommend the use of high quality RCA interconnects wherever possible, for the best quality sound. (e.g. REDGUM's RGAP 05 & RGAP 1) The amplifier inputs are all the same sensitivity, and will accept a signal from any line-level source (Media servers, Tuner, MP3, etc.).
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.

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.

Adjusting the relative loudness of different audio channels There are four rotary controls at the rear of your pre-amplifier. These allow you to individually control the loudness of the rear, centre and subwoofer channels in relation to each another and the front speakers. These volume levels are pre-set in the factory to the industry standard for 5.1 channel surround sound.

Rear speakers Rear speakers should be placed alongside and slightly to the rear of the listening position, but not behind it. It is also important to elevate them so that they are well above your head when you are seated. They should be pointed directly at the listening position, but not angled up or down.

Too many soft surfaces? If your room is too damped, try removing some of the soft furnishings from the walls, or rugs from the floor. Managing the bass Sometimes, low frequency waves can also bounce around and cause problems in a listening environment. This may be the result of the shape of the room, or the materials it is constructed from.
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 StandBy power system incorporating a highly efficient miniature power supply that powers a microprocessor using 'nanowatt' technology.

Lost Keys 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.
