We at Rogue Audio truly believe that our amplifiers provide the “smartest” value in high-end audio. If you have never owned a vacuum tube amplifier you will be thrilled by the silky-smooth sound and incredible detail that only a tube amplifier can provide. And with the Apollo monoblock amplifiers, you can be sure that you are getting the very best in tube amplification. We at Rogue Audio are extremely proud of our products and want you to enjoy them to their fullest potential. So please, take the time to read through this short manual so that you can be confident that you have set up your amplifier properly. UNPACKING THE APOLLO MONOBLOCKS Tools required: none WARNING -This amplifier uses voltages that could cause injury or death. Never open the amplifier while it is plugged in, and always wait at least one hour after turning the unit off to unplug and open the unit. Lethal voltages can remain in the electronics after the unit is unplugged. The Apollo amplifier has been painstakingly inspected for cosmetic flaws during and after assembly. In order not to damage the cosmetic appearance of your amplifier it is important that you follow the unpacking instructions carefully. 1. Carefully lift the outer box up and over the amplifiers. 2. Remove the foam pads from the top of the amplifiers. 3. The Apollo has two built in handles on either end of the amplifier. Remove any rings or jewelry that can scratch the aluminum finish. CAUTION – The Apollo amplifier weighs 100 pounds. Carefully lift the amplifier and move it to its operational location. Note – this is not a one person job! 4. Save the packing materials. The packing materials and box have been carefully designed to protect your valuable equipment during shipping so you don’t want to throw them away. 5. Align Tubes -Using a glove or a clean dry cloth, straighten any tubes that may have tilted during shipment. Ensure that all of the tubes are fully seated in their ceramic sockets. CONNECTING THE APOLLOS INTO YOUR SYSTEM Connecting Apollo to the Loudspeakers: The rear panel has binding posts for both 4 and 8 ohm loudspeakers. The 4 ohm taps are those located closest to the right of the amps rear panel. The 8 ohm taps are located nearest the left side of the rear panel. In general, if your speakers are rated at less than 6 ohms, use the 4 ohm taps and use the 8 ohm taps if they are 6 ohms or greater. Connecting Apollo to the preamplifier: There are three types of input connections on the rear panel of the Apollos: 1) Fully balanced XLR type input. 2) RCA 1 input 3) Balanced RCA 2 input For lowest noise levels, we recommend using either the balanced or RCA2 inputs which go through the balancing circuitry for partially balanced operation. If you have a preamp with a high output impedance you may choose to use the standard RCA inputs to achieve proper bandwidth. Note that a second preamplifier or home theater processor can be connected to the second set of RCA outputs. Figure 1. Rear panel layout Connecting Apollo to the power outlet: Your Apollo monoblocks have been provided with high ampacity power cords. Use these cords to connect the amplifiers to the wall outlet. It is recommended that you use the same outlet as the preamp to avoid creating a ground loop. It is also recommended that you do not use a power conditioner as it may limit the current available to the amplifiers. OPERATION OF THE APOLLO AMPLIFIERS After all proper connections have been made, you are now ready to turn the Apollo amplifiers on. The power on/off switch is located on the front top of the amp between the triode/ultralinear and standby switches. Some preamplifiers and sources can generate dangerous transients that can damage loudspeakers. To avoid letting dangerous transients reach your loudspeakers turn your system on in the following order: 1) Turn on all sources (CD, tuner, etc.) that you will be using. 2) Turn on the preamplifier. 3) Wait until preamp has stabilized. 4) Power up the Apollo amplifiers. 5) Select listening source and play music When powering down your system turn the amplifier off first. Note – Important! After turning off the amplifier, wait at least one minute to turn it back on. Do not turn it on then off and then on again in quick succession. Doing this will not allow the power supply to discharge between on/off cycling and may result in transient noises. If short term on/off cycling is necessary, restart the amp in standby mode. Triode/Ultralinear switch: The output transformer of a tube amplifier acts as the electrical interface between the very different impedances of the loudspeaker and ...
