CONNECTIONS

Important: Ensure the rear panel power switch is in the off position whenever changing

connections. Also ensure that the power amplifier is off.

1) Connect one or more source components to the Calypso's inputs. Both balanced and

single-ended connections are provided for each input. A tape deck may be connected

to the tape input / output connectors. The tape output is unbuffered.

2) Using either the single-ended (RCA) or balanced (XLR) outputs, connect the Calypso

to your power amplifier. Use of balanced connections will yield 6dB more gain.

3) Connect the supplied IEC power cord to the back of the Calypso and to an

unswitched, grounded AC outlet. Line conditioners may be used with the unit if

desired. Ensure the maximum power of the conditioner is not being exceeded.

Note: The input circuitry of the Calypso accepts a maximum input voltage of 3.5v rms

single-ended or 7v rms balanced. This is well above the industry standard 2v rms single-

ended or 4v rms balanced. However, there are a few source components that exceed this

limit. If the offending source component has a volume or gain control, all that is

necessary is to reduce the gain or volume of the source component. In other cases, it will

be necessary to have the source component modified to be within industry standard

specifications. A clear indication that this limit is being exceeded is a raspy distortion or

compression of musical peaks.

OPERATION

STANDBY

AC power is applied to the unit by pressing on the left side of the power switch, when

viewed from the front of the unit. When Calypso has power applied for the first time, it

will first display the installed software version on the LED display for two seconds, then

automatically enter the standby mode. While in standby, power is applied to all circuits

except the vacuum tube heaters. The high voltage supply is reduced to a level that is safe

for the vacuum tubes. All solid state circuitry in the Calypso remains powered. Anytime

Calypso is in standby, the standby light will be illuminated.

Pressing the standby button will take Calypso out of standby. The standby light will

blink for 30 seconds, during which time the heater supplies will be energized and the

high voltage supply will rise to operational levels. After the warm-up period, the standby

light will extinguish and the input will be displayed, and the mute light will be

illuminated indicating the Calypso is muted.

Place Calypso in standby when not in use.
