Precautions 1 . Power Supply Unit (RPS-7) The RPS-7 is separate f ro m the console. I f the power switch on the RPS-7 is turned " o n " without a connection between the RPS-7 and t h e board usin g the accessory cable packed i n the RPS-7, p o w e r is n o t supplied to t he board.
General Description TOA's R X - 7 is a modular 1 6 , 24 or 3 2 input channel, 4 group output, 4 to 8 program output mixing console. It is designed t o meet a wide variety o f requirements in professional sound reinforcement an d recording applications.
GROUP/FOLDBACK a n d GROUP/ECHO MODULES 1 . AUX INPUT (Group/Foldback Module) an d E CH O I N ( Gro up /E cho Module) are both balanced (transformer-isolated), with Low, Mid and High-EQ provided for bo th types o f inputs. 2. ACCESSORY SEND/RECEIVE jacks a r e located on the rear o f the modules f or inserting signal processing devices.
PROGRAM MODULE 1 . Group 1 , 2, 3 and 4 controls p ick up t he signal from t he four group out busses and assign them to the program output. Th e program output i s therefore suitable fo r feeding the signal t o t h e house sound system.

General Information o n using th e mixing console * Impedance Generally speaking, there ar e two rules to follow when connecting equipment o utp uts to the inputs o f other equipment. 1 . T ry to properly match the impedances o f the outputs an d i nputs.
* Ground loops AC ground i s provided to the RX-7 and al l associated equipment, an d this may cause an increase in h u m noise if care is not taken in connecting other equipment to the mixer. This is because a ground loop is m ade through the shields of th e connection cable and the AC line as shown in F i g.
The RX-7 i s a sophisticated mixer with many functions. Details on important functions a r e shown below in order f o r you to get the best operation and performance an d al s o t o avoid mistakes in operation.
The tri m control changes the negative feedback volume, so that the ga in o f the head amp can al so be changed. T HI S FUNCTIONS T O YIELD TH E B E S T COMBINATION OF MAXIMUM HEADROOM AND MINIMUM NO IS E CHARACTERISTICS.
* Equalizers The RX-7 equalizers provide lo w and hig h frequency shelving and mid-range peaking, both boost a nd attenuation. T h e m id-range E Q center frequency c a n b e s e t a t a ny frequency between 200Hz a nd 5kHz w it h a continuously variable frequency knob.

Portable Entertainment Sound Reinforcement Set-Up TOA's R X -7 consoles are designed to help out when you're out on th e road. We're sure you'll find j u s t the r ig ht set-ups f o r each show, but we w anted to s how o ne wa y i t migh t be done.
Multi-Track Recording or Track-Down The TOA RX - 7 series of mixing consoles allows better recordings as w ell a s better concerts. F or multi-track recording, direct outputs o n ea ch input channel can be connected to multi-channel recorder inputs.
How t o remove modules 1 . Remove the armrest from th e cabinet in the following manner. *Pu t both hands under the armrest and lift it straight up to remove. (Fig. 24) 2. Loosen t he t wo captive screws on th e front o f the meter panel and lif t panel straight up.
(Fig. 26) 3 . Rem ove the tw o binding screws on each module. Put your fingers i n the two holes o n t h e to p a nd bottom o f th e module and lift t he module straight up to remo ve it from the cabinet.
