System Expansion Guidelines to connect the SP 230 to:

1. A second SP 230

- Switch one SP 230 to ”slave” position, then

- CBL 1015 75 Ω coax plus 2 cable, 18 AWG, 100' or

- Plug Mains cable into 110 V AC wall outlet and connect RF signal with RG 58 coax cable

using BNC connectors or barrier strip

2. SZI 1015 Emitter

- CBL 1015 75 Ω coax plus 2 cable, 18 AWG, 100' *

3. SZI 1029

- RG 58 coax cable with BNC to BNC

- Plug Mains cable into 110 V AC wall outlet

* Note: For runs longer than 100', use heavier gauge

SP 230

The compact, portable SP 230 is a two-channel self-contained modulator/emitter in one
unit that operates at higher sub-carrier frequencies thus avoiding interference from
uorescent lighting.

It is especially well-suited to medium sized conferences and meeting room applications, as
it can be set up easily on a podium or microphone stand and requires only the simple
connection of a microphone, tape recorder (or similar audio source), and a wall outlet. It
can remotely power one SZI 1015 medium area emitter panel for up to 4,000/2,000 sq. ft. of
additional coverage (single-/two-channel mode).

SP 230

The system must consist of a two channel wideband modulator capable of switching
between channel one at 2.3 MHz; channel two at 2.8 MHz; or stereo; and, an emitter with
an array of 72 diodes providing 4,000 sq. ft. of coverage in a single channel; or 2,000 sq. ft.
in two channel mode. It must plug into a standard 110 V AC power outlet. The single
component design must be capable of being placed on a at table or mounted on mic
stand using a 5/8" thread adapter. The emitter must indicate proper functioning by a green
LED; a red LED would indicate no RF signal. The internal transformer power supply must be
capable of remotely powering a second emitter of equal size. Connecting the RF signal to a
second emitter must be accomplished in one of two ways: BNC and 50 Ω coax cable, or
using the barrier strip with tinned leads.

The modulator must accept either line level audio input via 1/4" phone jack; mic level audio
input via XLR connector or both. When using a combination of line level and mic level
inputs, mixing the two sources must be easily accomplished using a control knob to
achieve desired output. It must include a line output for connecting to a recording device
or room PA system. The unit must have a optional carrying case for easy transporting.
