ASHDOWN ENGINEERING - 12-BAND 600

USER GUIDE

Above this frequency range you will find it is better not to boost the signal as this

will mainly emphasise any hiss present. This hiss will not be masked by the bass

signal when playing due to the very small amount of bass guitar frequency content

at 10 to 15kHz.

Use the 30Hz and 40Hz sliders sparingly unless you have a massive stack of

speakers available, and the power amplifiers to drive them. You will find that rolling

off the bottom end by using these two sliders will allow you to play at a far greater

volume level without the speakers complaining.

Try to keep the graphic sliders balanced around 0dB and in a smooth flowing curve

from one slider to the next, and remember that after adjusting the graphic you may

need to re-set the INPUT GAIN.

DI - The DI or DIRECT INJECT socket is a balanced, low impedance XLR output

intended for connection into the Microphone Input on one channel of a mixing

desk. This is to carry the signal to the P.A. system for larger gigs. It is balanced and

low impedance to ensure that no noise is added to the signal on the way to the

mixer. The level of this signal has been set to be similar to that from a microphone so

that it will work without overloading the input on a desk that has no input Pad switch.

The signal connections are as follows: Pin 1 = Ground, Pin 2 = Signal +, Pin 3 =

Signal -. The DI signal can be switched to be PRE or POST EQ. PRE EQ is before any

of the amplifier's facilities or EQ but after the INPUT GAIN control. POST EQ is after

all internal facilities and includes the external effects loop.
