Connecting Speakers The Wall-Rock and Rock-Star incorporate a 900 Wrms power amplifier for the speakers. This amplifier is connected to the Internal Pre-amplifier output and adjusted using the Internal volume controls. The output of the power amplifier is connected to a 70046-1A Audio Distribution Transformer unit that matches the power from the amplifier to speakers loads from 1/8 Ohms to 8 Ohms. In addition, outputs for 70 Volt CV systems are provided. If more power is required for an installation, the 900 Wrms amplifier may be replaced with a 1,500 Wrms or even a 2,600 Wrms power amplifier. These optional amplifiers may NOT be used with the 70046-1A Audio Distribution transformer unit and drive 2 to 8 ohm loads directly. The chart below gives maximum wattage per speaker that may be delivered by the different amplifiers. The left column is the number of 8 ohm speakers connected to a particular channel. Go to that number and follow across to see what the maximum wattage per speaker will be: Maximum Watts RMS per Speaker # of 8 Ohm Speakers System PV-900 w/ per channel Impedance 70046-1A PV-1500 PV-2600 1 Speaker / channel 8 Ohms 450 Watts 300 Watts 540 Watts 2 Speakers / channel 4 Ohms 225 Watts 250 Watts 400 Watts 4 Speakers / channel 2 Ohms 112 Watts 185 Watts 325 Watts 8 Speakers / channel 1 Ohm 56 Watts * * 8 Speakers / channel* 2 Ohms* 56 Watts 94 Watts 162 Watts * Wire the speakers in a series / parallel (SP) arrangement to maintain a minimum 2 ohm impedance. WARNING: Do NOT use the 70046-1A Audio Distribution Assembly with the PV-1500 or PV-2600 amplifiers. The rest of this section assumes the standard equipment PV-900 Power Amplifier and Audio Distribution Assembly is used. It is also assumed that you are familiar with the Amplifier Description and Operation section (Section D) of this Service Manual.

The figure above is representation of Rock-Ola s Audio Distribution Assembly. Its purpose is to match the external speaker load to the Peavey Power Amplifiers output so that the maximum amount of power may be delivered to the speakers. Before connecting extension speakers, you need to calculate the impedance load for each channel. To calculate the load, (assuming like impedance speakers) divide the number of speakers into the Ohms value of one speaker. For instance, if you have two 8-Ohm speakers per channel, the impedance is 4-Ohms. (2 divided into 8 equals 4.) The speakers will be connected to the 4-Ohm tap. Normally, when wiring speakers, they will be connected to the appropriate impedance tap. However you may also distribute speaker power. The chart below shows the maximum Wattage delivered to a single 8-Ohm speaker when it s connected to a particular impedance tap. It also shows the maximum number of 8-Ohm speakers that may be connected to a particular tap. Power Distribution Chart for PV-900 Amplifier w/ Audio Distribution Assembly (per channel) Impedance Tap Max Power (Wrms) per 8- Ohm Speaker Max Number of 8-Ohm Speakers that may be connected 8 450 Wrms 1 4 225 Wrms 2 2 112 Wrms 4 1 56 Wrms 8 1/2 28 Wrms 16 1/8 7 Wrms 64 To distribute power, connect 8-Ohm speakers to the taps and add together the Max Power per 8-Ohm Speaker. Make sure the sum is less than 450. NOTE: Be sure the speakers you use match the power rating for the tap to which they are connected. IMPORTANT: The Amplifier will automatically limit if there is an overload. If the Red DDT LED s on the front of the amplifier are illuminated most of the time, then an overload condition exists and must be corrected. Turn down the gain controls on the front of the amplifier or limit the maximum volume in the operator console until the DDT LED s are out or just flash briefly with music peaks. Operating the unit with the DDT LED s fully lit may result in an overheat condition may damage the amplifier and/or the speakers. Rock-Ola Mfg. Corp. C3-8 Operation & Service Manual
Power delivered to each speaker:! WARNING Be sure maximum power rating of the speaker used is higher than the maximum power delivered. Fig. 3-C3 Rock-Ola Mfg. Corp. C3-9 Operation & Service Manual
Connecting to Additional Power Amplifiers or House Systems The jukebox may be connected to an additional power amplifier to yield 2 zone stereo by leaving the amplifier inside the jukebox connected as a single room installation and the additional amplifier powered by the signal available at the EXT output RCA jacks. The INT volume control will then operate the jukebox system and the EXT volume control will operate the external power amplifier. If the output to the external amplifier is to be set and left unchanged, simply set the maximum and minimum limits to the same value. (See programming audio system). If the jukebox is to be connected to a House system to provide all of the amplification, the House system may be fed with either the INT or EXT output RCA jacks. If the volume is to be controlled via the House system, then the output of the preamplifier may be frozen by setting the minimum and maximum levels at the same value. NOTE: It is highly recommended that the Fixed output or the direct output of the Core NOT be used to drive the house system unless that system contains ground loop elimination circuitry and audio processing that will compensate for a variation of signal level from one selection to the next. (AVC). These features are built into the Rock- Ola Preamplifier and appear at the INT and EXT outputs. Fig. 4-C3 - Pre-Amplifier Rock-Ola Mfg. Corp. C3-10 Operation & Service Manual
Section C3 - Placing on Location Connecting A Paging Microphone Rock-Ola s Advanced SyberSonic Amplifier can accept virtually any paging microphone. Pictured below are wiring diagrams for the most common paging kits. Installation Instructions for Yoga Paging Kit #02379-02 are in Section J of this manual. The necessary connector is included with Rock-Ola paging kit. To use other paging kits you will need to acquire one (1) Amp part number 640250-4 housing (RMC P/N ST-11244) and four (4) Amp part number 640252-1 contacts (RMC P/N ST-11245) or equivalent. The paging system works by sensing audio on the signal line. Whatever microphone is used, it must have some kind of switch to mute the audio when not in use. Set the Microphone gain switch to LOW and the gain control at midpoint. Press the talk button on the microphone and speak into it. The Status LED on the amplifier should blink and the microphone signal should be heard in the speakers. Adjust the microphone gain control to the loudest level you want the location to be able to have. If more gain is necessary, turn the microphone gain switch to HIGH. CAUTION: Be sure the gain control is turned down to avoid speaker damage from acoustical feedback. Rock-Ola 02379-01 Red Black Shield Yoga Microphone Kit 02379-02 Refer to the amplifier settings for adjusting which channels to hear paging, the music level while paging, and length of time before the music comes back up. NOTE: If the jukebox is idle with auxiliary background music inputs off, there will be a short delay of approximately 2 seconds for the amplifiers to wake up when a paging signal is detected.
