INSTALLATION OF ACCESSORIES1. Low-Level, Passive Bi-Amp and Tri-Amp Crossover Networks
2. Input and Output Transformers
3. Pink Noise Generators
4. Other Special Filters and Accessories
If your application does not call for the installation of plug-in accessories, make certainthat the THREE jumper plugs (4438, 4439 and 4440) are installed in theirAPPROPRIATE sockets. Please proceed to the next section: Connections To The SoundSystem.
CAUTION
The Plug-In Accessories must be anchored by inserting two "speed" type nuts, providedwith the accessory, into the equalizer's chassis. Once anchored in this manner theaccessory may be somewhat difficult (though not impossible) to remove. TWO of theTHREE accessory sockets are IDENTICAL. Make certain you anchor the accessory intothe CORRECT socket the FIRST TIME.
Support the front panel of the equalizer with one hand while gently and evenly applyingpressure with the other hand to push the accessory into its socket. Make certain theaccessory is inserted ALL THE WAY into its socket.
CONNECTIONS TO THE SOUND SYSTEM:The equalizer is connected to the sound system via two barrier terminal strips. Interfacewiring to the equalizer should be high quality, two conductor, shielded cable terminatedwith insulated, #6 Spade Lugs.
The equalizer is constructed so that the audio circuitry is isolated from the chassis. Thechassis is connected to EARTH through the power supply wiring.
It is not the purpose of this manual to provide a dissertation on sound system shielding,grounding and safety techniques. However, a few tips are in order.
1. NEVER remove the grounding lug from the AC power supply. To do so is dangerous(and unlawful in most jurisdictions)! Further it is unnecessary since the audio processedby this unit is already isolated from AC ground.
2. A good technical ground can be achieved through the proper design and installation ofthe AC system.
3. It is a generally accepted practice to connect the shield to AC ground at only ONE endof the cable. The other end of the cable should be left open or connected through a .01 uFcapacitor. For this reason the illustrations in this manual show the shield conductor as adashed line (meaning optional).

INSTALLATIONAll audio input and output connections should be made BEFORE power is applied to theequalizer.
The Model 4500 power supply to equalizer connection should be made BEFOREAC is applied to the 4509 power supply.
INPUT CONNECTIONS
The inputs of the Models 4400, 4240A and 4200A are electronically balanced.
The input to the Model 4500 is unbalanced and buffered.
An accessory input transformer is available Model (4390). This transformer will providean isolated input to each Model and present several opportunities to reduce or eliminatehum and/or RFI caused by ground loops and EMI.
The terminals on the Input Barrier Strip are labeled as follows:
l. "+" = Audio + or High Leg. With or without accessory input transformer.
2. "-" = Audio - or Low Leg of accessory input transformer primary. When inputjumper plug (4438) is installed, this terminal and the COM terminal are connectedinternally.
3. "COM" =Audio Common, - or Low Leg. With or without accessory inputtransformer. One side of the accessory input transfromer's (4390) secondary is connectedto this terminal internally.
4. "///" = Chassis, AC ground.
Figures 1 and 2 illustrate the input connections with and without the accessory inputtransformer. Note the use of the "-" and "COM" terminals.

AC POWER CONNECTIONSMODELS 4200A, 4240A and 4400 utilize 115/230 Vac at 50/60 Hz with a 0.25amp.slow blow fuse. There is no on/off switch on these units.
The Model 4500 is shipped with a Model 4509 external power supply for 115 Vac, 50/60Hz operation. The 4509 power supply is equipped with internal, thermally activatedcircuit breakers which reset automatically. In addition the Model 4500 equalizer isprotected with two internal, fail-safe fuses.
COLOR TRANSITION THRESHOLD LEVEL CONTROL (4500 Only)In its full CW rotation the control causes the power/clip LED to change from green to redat approximately 3dB before clip. As the control is rotated CCW the level at which thegreen to red transition takes place is lowered. No calibration is given for the control. Notethat this control only effects the LED's color transition and not the level at which theequalizer will clip.
The Model 4500 is not equipped withan AC on/off switch. The unit is turnedon when AC is applied to its powersupply. The front panel LED will lightgreen.
When powering up ANY PART of thesound system always turn the poweramplifiers on LAST.
When powering down ANY PART ofthe sound system always turn thepower amplifiers off FIRST.
