Installation
The 7130 is suitable either for rack mounting in two E I A rack
spaces without additional bracing or ventilation, or for counter-
top placement. A full set of mounting hardware is packaged with
each unit. All external connections are made on the rear panel,
Figure 2.
Operating Temperature
The maximum allowable ambient temperature for the 7130
is 6 0 ° C ( 1 4 0 ° F ) .
Operating Controls
All operating switches, meter, threshold and level controls,
except for M I C / L I N E input selector switches, are located on
the front panel, Figure 1.
Input Connections
Input connections to the 7130 may be either direct coupled or
transformer isolated at the XL-type sockets or screw terminal
boards, Figure 2.
Direct coupling is accomplished by connecting either the center
conductor of a shielded cable to D I R E C T (line input) and the
shield to GND, or the center conductor of a shielded cable to
pin #2 (XL-type connector) and the shield to pin # 1 .
For transformer isolated inputs, a 5901 universal microphone
transformer (for microphone inputs) or a 5195 matching/bridging
transformer (for line inputs), Figure 3 and 5, may be used.
Transformer isolation is accomplished by connecting the clear
conductor of a two conductor shielded cable to HI (line input),
the black conductor to the L O and the shield to GND, or the
clear conductor of a two conductor shielded cable to pin # 3
(XL-type conductor), the black to pin # 2 and the shield to
pin # 1 .
Output Connections
Output connections to the 7130 may be either direct coupled or
transformer isolated at the screw terminal board, Figure 2.
Direct coupling is accomplished by connecting the center con-
ductor of a shielded cable to D I R E C T and the shield to GND.
Transformer isolated output is accomplished by connecting the
clear conductor of a two conductor shielded cable to the HI,
the black conductor to the L O and the shield to GND.
Installation of Microphone or Line Transformer
To install the optional transformers. Figure 3 or 5, (Model 5195
or 5901):
1. Remove the two copper jumpers between terminals 8 & 9
and 4 & 5.
N O T E : Remove only the jumpers from the 9-pin socket
in which the optional transformer is to be used.
2. Install the optional transformer per Figure 4.
NOTES: 1. 600 n source.
2. Measured at 0.5% THD.
3. ATTACK and R E L E A S E times set to slow.
4. At+18 dBm.
5. Requires a 20 Hz—20 kHz equivalent bandwidth filter.
