If water or any metal object (such as a paper clip, coin, or staple) accidentally falls inside the unit, disconnect it from the AC power source immediately and contact Cary Audio Design for further instructions. HEAT: Position the unit away from heat sources such as radiators, heat registers, stoves, or other units (including amplifiers) that produce heat.

(preferably unplugging them from the AC power source). Many audio components feature automatic turn-on circuits that may activate during an installation, potentially causing damage to electronic components and/or speakers. This type of damage is not covered by product warranties, and Cary Audio specifically disclaims responsibility for any such damage.
The cinema bypass circuitry may be engaged by toggling the Cinema bypass switch on the front panel of the preamplifier. If the SLP 05 power switch is turned to the off position, the SLP 05 automatically defaults to the cinema bypass mode.
WELCOME CIRCUITRY The SLP 05 is a no compromise line stage and headphone amp. The power supply is vacuum tube rectified and has a 5AR4 vacuum tube rectifier lying on its side inside the unit. The 5AR4 tube has a separate cathode from the filament so any position of mounting is proper. It was horizontally mounted to keep the power supply the same height as the preamplifier.
Cary Audio Design within 15 days of your purchase. Warranty restrictions apply. Consult the warranty section of this manual for details. Please keep a copy of the original sales receipt from your Authorized Cary Audio Design dealer to validate the warranty if necessary.
SPECIFICATIONS Operating the SLP 05 Preamplifier is a simple procedure since each unit is designed for long- term stability in virtually any home operating situation. However, if the unit is operated outside the parameters outlined in this owner’s manual, damage may occur. Please read this manual carefully before operating your new SLP 05 Preamplifier.
The SLP 05 has a timer warm up circuit that allows safe use with “rapid turn on” solid state power amplifiers. The headphone power amplifier, using two 6SN7 octal vacuum tubes, is coupled through audio transformers to produce 1/2 watt per channel to drive your favorite high quality headphones.
5. OPERATE/MUTE This bat handle switch will either mute the output of the SLP 05 or allow the signal to flow to the basic power amplifier in the system. In the MUTE position the external hand held remote unit will take over the mute/operate function.

3:00 o’clock or even all the way up. This does not stress the SLP 05 in any fashion. The SLP 05 is a Class A operating circuit and in reality is running at full potential at all times. The listening level control simply controls the input voltage level flow.
CONTROLS REAR PANEL PREAMPLIFIER Special Note: The balanced input and output XLR connectors follow the ITT Cannon pin out configuration. This pin-out calls for the shield to be wired to pin #1. The normal- phase (hot) is wired to pin #2. Pin #3 is the inverted phase. CINEMA INPUT FROM PROCESSOR –...

CONTROLS REMOTE CONTROL The SLP 05 remote control included with the SLP 05 is designed to function with several of our products. For use with the SLP 05, only the “Volume” and “Mute” buttons on the bottom of the remote will be used. If you have a CD-500 disc player, many of the other remote functions will be used to control its operation.
When you activate the preamplifier power on switch you will notice a blue LED showing at the left lower side of the front panel. This indicates the SLP 05 is receiving the necessary power from the matching supply. After approximately 60 to 90 seconds please observe the red LED labeled ready.
Unplug the unit from the wall outlet before cleaning. Clean the cabinet housing and front panel of the SLP 05 with a soft cloth and a glass cleaner (such as Windex). The frequency of cleaning will vary based on the cleanliness of the environment and the number of hours the SLP 05 is operated.
