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.
When done manually, the simplest way to alter the volume level
involves only one hand and is done by ear, so the setting chosen
automatically adjusts for your room acoustic at the same time. To do
this, set the volume for one channel at the generally desired level.
Then by focussing on the other channel, bring the volume up till the
image appears central.
Alternatively, the dual volume controls can be moved together easily,
again using only one hand. Place the outer side of your hand onto the
top of the two controls. With a slight downward pressure to maintain a
“grip” on them, slide your hand to the left or right to adjust the volume.
Should it be required because of room acoustics, further fine
adjustments can be made with the individual controls once the volume
level and position of image has been chosen. If preferred, a belt is
available from the manufacturer that circles the two controls so they
move together when only one control is turned.
For Remote Control models, the same left-right volume adjustment is
done via the remote's Left-Right Arrow buttons.
Except
for the “Bal”
(Balance) and “Mute” buttons, all functions are as commonly used in
remotes of all kinds.
N.B. The “Mute” button cuts the volume by approximately 15dB, i.e. it
is a partial rather than total Mute. Pressing the “Bal” (Balance) button
is the quick way to match the volume levels of both channels. This
results by recalibrating the levels up to 200 times within 2 seconds to
a-0.1dB balance.
For greater detail about the basic functions of the Dual Mono Remote
Control, please see the “Firmware” page.
In addition, using the Dual Mono Remote Control, each amplifier can be
personalised using REDGUM's own Control Options software (see
separate Technical Information Section handout). For example, these
options provide choices of a Professional Fade, “Memory Select” of last
remembered volume level, and “Volume Control Movement” to help
maintain the customer's intentionally set balance differential.
