MAKING CONNECTIONS TO
THE PROGRESSION AMPLIFIER
Speaker cables
Install the speaker cables first. We recommend the use of high-quality cables terminated
with spade or ring lugs that will fit the Progression's binding posts. Alternatively, the use of pin
connectors, banana plugs, or bare-wire connections is acceptable. Note that the positive (+)
binding post has a red ring and the negative (–) binding post has a black ring. Double-check to
confirm that you are connecting the cable's conductors to the appropriate binding posts—red
to positive, black to negative. If your cables are marked to show desired signal flow, orient the
cable to conform to the cable manufacturer's instructions.
To install speaker cables tipped with spade lugs or rings, carefully loosen each speaker binding
post. Turn counter-clockwise to loosen. If using spade lugs, insert each spade lug so that its
two tines straddle the binding post, then tighten the binding post nut. If using rings, remove
the binding post nut entirely, place the ring on the binding post, then replace the nut and
tighten it securely. A firm connection, tight enough that the spade lug or ring cannot move, is
all that is needed. Overtightening could damage the binding posts. Do not use a conventional
wrench to tighten the binding posts.
Interconnect cables
We recommend the use of a high-quality balanced XLR audio interconnect cable with the
Progression amplifier; one for each mono and a pair for the stereo version. If your preamp
does not offer XLR outputs, use a high-quality RCA-to-XLR adapter. Connect the XLR cable to
the input by pushing the cable onto the jack. To release the XLR cable, push on the small tab
on the end of the jack, then grasp the cable by the plug and gently pull it out. Never grasp
interconnect cables by the cable itself—you could damage the cable.
AC cord
The Progression amplifier is supplied with a high-quality AC cord tipped with a 20-amp IEC
connector at the amplifier end and a three-conductor AC plug at the other end. You may use
a different power cord with the Progression amplifier if you wish, as long as it is tipped with
a 20-amp IEC connector and a three-conductor AC plug. After the speaker and interconnect
cables are connected, push the IEC connector on the power cord into the IEC jack on the
Progression amplifier.
12 V trigger on/off input and output
The input allows you to turn the Progression amplifier on or to standby from other components.
The output sends 12 VDC (12 V trigger) power on/off signals to other Dan D'Agostino Master
Audio Systems components or other devices that incorporate a 12 V trigger input. Mono
3.5 mm connectors are used in the following configuration: Tip = +12 V, Sleeve = GND.
