LINK: 1/4" TRS jack for connection to another RA53 LINK jack. Linking two units together provides 10 channels of monitoring from a master stereo signal, with four channels having an insert option. RIGHT/STEREO INPUT: 1/4" TRS jack for connecting the "Right" side of a stereo signal. If used alone, a 1/4" TRS plug with the "Right" side of the program material on the tip, and the "Left" side on the ring may be connected for stereo operation. For example, a stereo headphone output from a mixing console may be directly connected to the Right/Stereo jack via a stereo TRS cable. LEFT/MONO INPUT: 1/4" TS jack for connecting to the "Left" side of a stereo signal. If used alone, a 1/4" TS plug with a mono signal will feed both sides of the RA53 Outputs. AUX INPUTS: RCA input jacks for connection to a signal source such as a CD or cassette player. CHANNEL 2 INSERT: 1/4" TRS jack for receiving a stereo signal and directly accessing Channel Two output. CHANNEL 1 INSERT: 1/4" TRS jack for receiving a stereo signal and directly accessing Channel One output. 4560 VCC C14 1K UF 503 7 7 1 Q14 2N2907 Q15 MPSA06 R404 Q19 MPSA06 R503 Q18 2N2907 Q20 2N2907 R504 1N4001 C18 30 C15 1K UF VEE JAPDC D2 1N4001 D4 1N4001 30 30 VCC VEE VCC VEE VCC VEE VCC 30 Q13 MPSA06 Q16 2N2907 Q17 MPSA06 VEE R401 10 R402 10 PHONE 1/4 PHONE 1/4 R502 10 CHANNEL 5 CHANNEL 4 J5 D3 1N4001 J4 R501 10 D1 J11 PC 1/4 J12 PC 1/4 P1B P100K X2 4 56 R108 10K 4 1 1 C2 120PF 1 4 P3B P100K X2 56 R308 10K R107 10K R208 10K P1A P100K X2 P2A P100K X2 P2B P100K X2 56 R307 10K P3A P100K X2 3 3 R207 10K 2 2 2 3 C3 6 120PF C1 120PF C4 120PF C5 120PF Q11 4560 3 MPSA06 1 U3A 2 R303 3 4560 0 Q3 3 MPSA06 1 U1A 2 R103 U2A 2 6 U1B 5 6 U2B 5 4560 5 VCC 8 VCC 8 VEE VEE VCC 8 7 U3B 4560 4560 7 30 7 Q6 2N2907 VEE Q4 2N2907 1 Q10 2N2907 VEE Q8 2N2907 4560 4 4 C6 120PF J13 Q2 2N2907 Q7 MPSA06 VCC Q12 2N2907 R104 R204 R203 R304 30 30 30 30 30 2 3 1 VEE 2 CONNECTION Connect the Rolls PS12 Power Supply to the POWER jack on the RA53 rear panel. Connect the power supply to an ac outlet. Determine which input configuration you will use; either discreet right/left, TRS stereo, or mono. For a discreet right/left input configuration, connect a 1/4" TS plug containing the "Right" portion of the stereo signal to the Right/Stereo Input. [. . . ] Only the stereo signals sent to the Insert jacks go to the corresponding outputs. MODEL RA53 POWER 12VDC LINK RIGHT/ STEREO INPUT LEFT/ MONO INPUT RIGHT AUX INPUTS OPERATION Shown below is a possible operation example for the RA53. Headphones are connected to the Outputs on the front panel, and the other equipment is connected to the rear panel as shown.
