 INSTALLATION

 

 

The SGX LT may be used in a variety of setups including: mixing consoles with 

effect send and return facilities, straight into guitar or power amps, and in the 

effects loop of an amplifier. Self contained in an all steel single high 19" rack 

mount case, the SGX LT is designed for continuous professional use. For touring 

rack applications, care should be taken to support the units rear if the rack 

might be subjected to mechanical shock like dropping. NOTE: The front panel may 

bend if no rear support is provided. Mounting location is not critical, but for 

greater reliability we recommend that you not place the unit on top of power 

amps, tube equipment, or other sources of heat. 

 

POWER

 

 

This device is AC powered via a standard 3 conductor grounded power cable. Plug 

into any standard AC receptacle. We recommend the use of a surge protector to 

decrease the chance of equipment damage due to voltage surges or spikes on the 

line. For your own safety as well as the safety of others, do not remove the 

ground pin of the cable. Refer to the rear panel or the specifications for proper 

operating voltages.  

 

CONNECTIONS

 

 

Audio connections to the SGX LT are made at the front and rear of the unit via 

professional 1/4" phone jacks. The MIDI connection is accomplished via a five pin 

"DIN" jack on the rear panel. 

 

INPUTS:

 

 

There are two mono inputs available in the SGX LT. You can use both input jacks 

at the same time. However, the preamp output will be summed with the Line In 

input and then the combined inputs will be sent to the digital processor.  

 

INSTRUMENT INPUT

 

 

The Instrument Input on the front panel is a single ended (unbalanced) 

configuration with an input impedance of 470K ohms. This input is a direct input 

to the SGX LT's solid state preamp. Plug in all types of instruments to this 

jack. You may also plug "line" level devices into this input. 

  

LINE INPUT

 

 

The Line Input jack on the rear panel is a direct input to the digital processor. 

This input is a single ended (unbalanced) configuration with an input impedance 

of 1M ohm. The nominal operating level for this input is (-)10dB. Hook up high 

output instruments, recording devices, other outboard signal processors, and 

effects loop sends to this input.  

 

OUTPUT

 

 

The LEFT and RIGHT outputs are single ended (unbalanced) with an impedance of 

1.5K ohms, and can provide a stereo or mono output. When both outputs are used 

with one or both of the inputs, a stereo image is produced. If you do not want 

both output signals combined (such as only one delay time required), plug a dummy 

plug into the unused output. If you are only using one output use the Left 

output.
