Constellation Audio Argo - Manual (Page 6)

Source components
The Argo integrated amplifier has four analog audio inputs—two balanced (XLR) and two unbalanced (RCA)—
and can be used with any audio component with line-level analog outputs. An XLR connection will provide the
highest quality signal, and should be used when possible. If you are using a record turntable, you will need to
connect a high-quality phono preamp, such as the Constellation Audio Perseus, between the turntable and the
Argo integrated amp.
In the event of malfunction
Do not under any circumstances open the chassis of the Argo. There are no user-serviceable parts inside.
Opening the chassis can present a shock hazard even if the AC power is disconnected. Any alteration or
modification of the Argo’s internal parts or circuit will immediately void your warranty.
If your Argo does not function correctly, refer to the Troubleshooting section at the end of this manual. If you
are still unable to resolve the problem, contact your Constellation Audio dealer.
If liquid is spilled on the Argo, or if any metal object (such as a staple or a paper clip) is inadvertently forced
inside, immediately disconnect the AC power and contact your Constellation Audio dealer.
Input and output connections
1. XLR inputs
On the rear of the Argo integrated amp are four XLR inputs, two on each side. As you are looking at the rear
panel, the left two XLR inputs are for the right channel, the right two inputs are for the left channel. Underneath
each jack is the corresponding input number. Use of XLR connections is recommended for the best possible
audio quality. To remove an XLR plug, push on the tab above the jack and pull the plug out.
IMPORTANT NOTE: To preserve true dual-mono operation, the Argo uses a symmetrical circuit layout. This
configuration requires that the Argo’s back panel connections be laid out a little differently from those on most
integrated amps. For example, the left-channel connection for Input 1 is on the right side of the back panel,
and the right-channel connection is at the left side. Connecting the cables in the usual side-by-side fashion will
result in an incorrect installation and the mixing of sounds from different source devices.
The input numbers from left to right, looking at the back of the Argo are:
