Frequently As ed Questions
Shou d I use a Ba anced or Unba anced connection?
If your amplifi r has a tru balanc d input, w r comm nd you us th balanc d analog output from your Wadia
S7i Int grat d CD Play r / D coding Comput r. All things b ing qual, prop rly impl m nt d balanc d (also call d
diff r ntial) circuitry sounds b tt r than unbalanc d circuitry. Th Wadia S7i Int grat d CD Play r /D coding Comput r
is a tru balanc d d sign. It g n rat s th inv rt d signal in th digital domain and all subs qu nt proc ssing is
don in balanc d mod . Your Wadia S7i Int grat d CD Play r / D coding Comput r is d sign d to maintain many
of th advantag s of tru balanc d d sign wh n using th unbalanc d outputs. In addition, th Wadia S7i Int grat d
CD Play r / D coding Comput r output stag is capabl of driving both typ s of outputs simultan ously.
Why shou d I bypass the Preamp ifier?
A pr amplifi r is unn c ssary wh n using your Wadia S7i Int grat d CD Play r / D coding Comput r. Th Wadia
S7i Int grat d CD Play r / D coding Comput r provid s all th n c ssary control functions of a pr amp whil
th signal is still in th digital domain. This avoids th sonic d gradation caus d by analog circuitry, switch s,
and wir . Th Wadia S7i Int grat d CD Play r / D coding Comput r output stag can driv any pow r amplifi r
and any int rconn cts, v n at v ry long l ngths.
Does the Wadia Vo ume Contro compromise reso ution?
Th Wadia S7i Int grat d CD Play r / D coding Comput r us s th lat st g n ration of Wadia’s propri tary digital
volum control. Th volum l v l can b vari d in th digital domain by m ans of math matical manipulation of
th signal, liminating th distortion and nois that ar in vitabl with v n th b st analog volum controls. Whil
conv ntional thinking indicat s that r ducing th volum digitally can sacrific low l v l r solution, Wadia has
cr at d an innovativ solution. Wadia’s pat nt d digital filt ring algorithm produc s a 24 bit output rath r than th
16 bits stor d on th CD. This high-r solution signal is th n us d in th computations which in turn r duc th volum
l v l. This n w signal is f d dir ctly to th DAC chips. Through this innovativ m thod, th Wadia S7i Int grat d
CD Play r / D coding Comput r maintains high r solution v n at th low st volum control s ttings.
Can I bypass the Wadia Vo ume Contro ?
B caus th Digital Volum control do s not includ any analog circuitry, th r is non to b bypass d. Ev n th
math matical program st p that p rforms th Digital Volum Control calculation is an int gral part of th Wadia
DigiMast r filt r algorithm and th r for cannot b bypass d. If you do not n d th Wadia Volum Control, s t
it to its maximum l v l of 100 on th display.
What about Ana og Sources?
In ord r to fully r aliz th pot ntial of this typ of syst m, Wadia has a rang of Analog-to-Digital conv rt rs.
Now it is possibl to us analog sourc s, such as a tun r, tap d ck, or v n a turntabl (in conjunction with a
suitabl phono stag ) in your syst m without using a conv ntional analog pr amplifi r. Consult your d al r for
mor information on th Wadia Analog-to-Digital products.
Shou d I eave the Wadia S7i Integrated CD P ayer / Decoding Computer with the power on?
Th Wadia S7i Int grat d CD Play r / D coding Comput r is d sign d to b l ft with th pow r on with no harm
or w ar to th unit. All motors and las r circuitry turn off wh n th unit stops playing. If d sir d, th front dis-
play can b turn d off (s Turning off the Display und r Remote Operation). L aving th pow r on allows
th circuitry to r main in th rmally stabl , which provid s b tt r p rformanc and long r lif . Car ful list n rs
will notic that th sound of th Wadia S7i Int grat d CD Play r / D coding Comput r will improv st adily aft r
th unit is pow r d up. A n w unit will und rgo mor dramatic chang s wh n pow r is appli d for th first tim .
If you turn off your Wadia S7i Int grat d CD Play r / D coding Comput r for mor than an hour, you will find
that th unit will und rgo similar, but l ss dramatic improv m nt onc pow r is r appli d.
