Getting Connected
Speakers
Before we get into connecting speakers, there are two important issues to consider: speaker impedance and multiple
speakers .
The Casaman is rated to perform as low as 4
Ω (ohms)
. The
Ω (ohms)
rating is a measure of the speaker’s impedance .
Basically, the rating tells you how much amplifier power will be passed through
the speakers. For example, a 4
Ω (ohms)
speaker has less impedance than an 8
Ω
(ohms)
speaker, and thus will offer less resistance to the flow of energy from the
amplifier . With less resistance, a 4
Ω (ohms)
speaker will pull more power from the
amplifier than an 8
Ω (ohms)
speaker will . Since 4
Ω (ohms)
speakers are capable of
drawing out more of the amplifier’s power, 4
Ω (ohms)
speakers will play louder than
8
Ω (ohms)
speakers .
When connecting two speakers to a speaker output, this changes the impedance .
Basically, when two speakers of equal impedance are connected to a speaker
output, the impedance is cut in half . So two 8
Ω (ohms)
speakers connected to a
single channel now has a 4
Ω (ohms)
load . Because the Casaman is rated at no
lower than 3
Ω (ohms)
, you can only connect two speakers to a speaker output if
they are 6
Ω (ohms)
or above .
You can use speaker cable with either bare wire or banana plug ends .
If you are using bare wire, loosen the plastic cap on each speaker connector by turning it counter-clockwise. This exposes the
interior metal rod . You can either stick the bare wire through the hole in the rod, or line it around the rod itself . Then tighten
the cap to secure the connection .
If using banana plugs, first ensure that the plastic caps are fully tightened on the speaker terminals . Connect the speaker
cable by pushing the banana plug onto the speaker output with the pins properly aligned and color matched to ensure proper
polarity . If connecting two speakers, stack the banana plugs .
