Location

The Hercules II must be installed in an area with adequate ventilation. There should be at least 6 in/15 cm of

clearance between the vents on the side of the amplifier(s) and the nearest wall or cabinet. Ensure that no

curtains or shades can be lowered in a way that will block the amplifier's vents. If the amplifier is installed in

a cabinet or in an equipment closet, ensure that the cabinet/closet has adequate ventilation. Installation in

an unventilated cabinet or closet may cause the amplifier to overheat.

The amplifier requires a room-temperature environment to operation properly. Ambient temperature should

be about 70°F/21°C, plus or minus 10°F/5°C. Never install the amplifier in a place where it may be

exposed to direct sunlight, and do not install it next to a room heater, radiator, air conditioner, etc. Ambient

temperature can rise even more quickly with two Hercules II Monos, so if you place both of them in an

enclosed or tight space, make extra sure to provide plenty of ventilation and air flow.

Make sure that the amplifier will not be exposed to moisture. Do not locate it in an area where it might be

spilled on, and do not place it in a humid location (such as an unfinished basement).

Installing the Hercules II Mono or Stereo in a place where it will be exposed to direct sunlight or moisture, or

where it will not have adequate ventilation, will void your warranty.

Speakers

The Hercules II Mono and Stereo both have sufficient voltage and current to drive practically any loudspeaker

made, regardless of the speaker's impedance, sensitivity, or "power rating." However, the Hercules II Stereo

and, especially, the Hercules II Mono have enough power to damage some loudspeakers if used carelessly.

When you turn up the volume on your preamp, do it gradually. If you hear distortion, crackling noises, or

mechanical thumps from the speaker, turn the volume down immediately.

You can best appreciate the amplifier's performance by connecting it to a large set of full-range

loudspeakers. It will sound excellent with small speakers, too, but if you connect it to a small set of speakers,

avoid turning the volume on your preamp to maximum.

Constellation Audio is not responsible for damage of any speaker connected to the Hercules II amplifiers.

Do not under any circumstances open the cabinet of the amplifier. There are no user-serviceable parts inside.

Opening the cabinet can present a shock hazard even if the AC power is disconnected. Any alteration or

modification of the amplifier's internal parts or circuit will immediately void your warranty.

If your amplifier 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 any liquid is spilled on the amp, or if any metal object (such as a staple or a paper clip) is inadvertently

forced in through the vents, immediately disconnect the AC power and contact your Constellation Audio

dealer.
