3.1.3 ACTIVE/LOW: Impedance Input < 50k Ohm This input is
optimised for active pickup systems which require battery power. It is
also used for some Passive Magnetic/Low Impedance pickups but on
passives there will be a treble roll-off and hence a thicker more middle
biased sound. Input leads carrying active signals are not so sensitive
to shielding quality or cable length so leads up to 10m (33’) in length
are fine. Also suits "Line Level".
3.1.4 STEREO JACK INPUT
The general purpose stereo jack input feeds separate signals to both
channels controlled by their two gain controls. The signal on the ring of
the jack (usually a blue or black wire in cable) feeds channel 1. The
signal on the tip of jack (usually a red or white wire in a stereo cable)
feeds Channel 2. Check channel switching re. EQ & Notch Filter.
3.1.5 AUX IN/iPOD IN: Mini-Jack Socket
The Mini-Jack Socket (3.5mm diameter) on side panel is intended
mainly for connection of iPod for use of recorded music such as for
backing music, interval music or for tuition purposes. It by-passes Gain
& EQ and feeds into Master Volume Control.
ACW = Backing a knob off or turning it Anti-Clockwise.
CW = Turning a knob up or turning it Clockwise.
3.1.6 GAIN Knob: 0 -10 (0dB-32dB Gain)
Turn CW to increase the gain on Channel 1 only. Each dot marker
equals 2.5dB (approx) or +/- 40%
GAIN & MASTER: Joint Operation.
Method A. After plugging in at 0, turn Master up high then very gently
turn gain control up CW slightly until you have reached the desired
level for your instrument.
Method B. After plugging in at 0 turn MASTER knob up a little then
slowly increase the GAIN CW until the desired level for your instrument
is reached. If your instrument is then played harder or with higher
volume level, drop the gain back significantly in order to retain
headroom and clarity. Use the MASTER knob for the overall volume
required.
