MAXON AD-9 PRO.
A pure and crystal-clear analog delay with Maxon BBD IC (MC4107D). AD-9
Pro features up to 450mSec delay time with 4 pieces of MC4107D. With
the world�s first RMS level sensor and companding noise reduction
system, transparent analog delay sound is finally available in a
stompbox format.
With AD-9 Pro, typical aliasing and clock noises in analog
delay are minimized. Dynamic range was improved by 18dB and maximum
input level by 12dB, compared with AD-9. Improved low range response
yields bold sound. Excellent balance between low and high range offers
clear and firm delay sound without spoiling warm sound of analog delay.
Single Head/Dual Head Mode is switchable with newly added tape
echo multi-head simulation function. In Dual Head Mode, midstream delay
signal (which is taken from the middle of BBD delay circuit) is added
into normal delay signal. This feature provides extensive delay effects
such as tape echo multi-head simulation and ambience effect of a
concert hall.
- True Bypass Switching on both outputs with 4PDT mechanical
switch. No alteration to tone of dry signal when effect is bypassed.
- Two-way power operation, using 9V alkaline battery or optional AC adaptor.
(9V alkaline battery: more than 7 hours, 9V manganese battery: more than 2 hours) Easy-access, tool-free battery compartment.
- AD-9 Pro uses a stabilized DC to DC converter to bump up to 9V
(plus and minus 4.5V). Battery voltage drop and fluctuation of AC power
source do not affect the tone and function.
