CALLISTO REMOTE CONTROL

The Callisto may optionally be configured with remote control. This is not your average remote control, it is an entire system consisting of a main remote receiving / control unit and large stepper motors that turn the volume controls through a belt drive system. The system is completely electrically isolated from the Callisto, there is not even a ground connection between them! Audio performance of the Callisto is not compromised in any way with the addition of the remote control system.

Main unit
The main control unit contains the power supplies necessary to drive the stepper motors, the IR receiver, control system and displays. The display is a large four-digit blue LED numeric, which can indicate both left and right volume levels at the same time. There are four buttons on the main control unit: Volume Up, Volume Down, Mute and Phase.

Motors
The main control unit is connected to the Callisto through an RS232 cable. Inside the Callisto, there are two large high-torque stepper motors (one per channel) that are connected to the volume shafts through belts and pulleys. Also at each volume control is an optical sensor system that allows the remote system to determine if the user has manually changed the volume control and display the change.

Mute
A small circuit board is added at the rear of the Callisto with muting relays. These relays are not in the signal path, they simply short the output signal to ground when muted.

Phase
This is an option with the remote system. Two small circuit boards are added with phase relays.

Handheld remote
The handheld remote provides direct access to the following functions:
    Volume Up
    Volume Down
    Balance Left
    Balance Right
    Mute
    Phase (optional)
